X15 Build Project!

We seem to have lost the first few months of 2015, and it’s July already! We’ve been so busy working on some new projects and finding great new products we haven’t had time to write much. One of our facebook followers got in touch about their build project, and at first glance it was just another DIY build, few bits of wood with holes in, usual kind of thing.

11667892_489603897858431_174781697_n

The project is based on the X15 design (http://www.speakerplans.com/index.php?id=x15) a fairly straightforward trapezoidal mid-high speaker. There are a number of drivers that are suitable for this cabinets, on this occasion an Eminence Kappa Pro 15 was chosen for LF, and an Eminence PSD 2002 on a PH220 horn flare for top end.

just another DIY build??..

but one thing that’s a little different on this, it was built by a 14 year old lad who’s keen to get into the audio industry.

Its great to see new blood coming into the industry, bringing new energy and enthusiasm with them.

Well done Tadhg Sweeney

P.Audio PA-D99 Monster 2″ 150W Compression Driver

We’ve been conducting some tests with the this old school beast and we are suitably impressed. The giant magnet and large 4″ voice coil give great efficiency (111dB) and loads of power handling (150W). Just look how this giant compares to the 1″ B&C DE250:

The question most people have when looking at a large compression driver like this is will it play high enough? We’ve run some tests with the P.Audio horns PH.2380 (90×40) and PH.2723 (60×40). Please excuse the coloured lighting!

We took some rough measurements with the two horn flares (SPL not calibrated and measurements are subject to room reflections).

graph 1

Green = PH.2380, Red = PH.2723

This monster compression driver can certainly cover the entire high frequency spectrum from 1KHz to 20KHz. For certain music styles there is always the option of adding another device such as a super-tweeter to improve the response 6KHz upwards. This may be especially beneficial on certain horn flares such as the PH.2723 and fits with what you would expect of designs using the JBL 2445 or other large format compression drivers.

PLASA 2014

Its been busy month since we exhibited at PLASA London 2014 at the Excel Centre, we had a great show and met lots of existing and new clients.

Our display stand is modular, so once we’ve unloaded it doesn’t take too long to assemble, we arrived Saturday afternoon, and this is what it looked like at 1pm:

plasa beginning

 

By 4:00 pm it was finished: plasa 4

 

Our first appearance of dB-Mark at PLASA – we had the DP24, DP26 and D28 system controllers at the show, and we now also have stock of the DP36 and DP48. Our second year with PKN, and we received a lot of interested in this up and coming amplfier brand. plasa 2

 

We had a few people join us at this year’s show, including Faital Pro.  As a distribution fulfilment partner for Faital Pro we are able to look after the UK market quickly and effectively, utilising stock from our UK warehouse – next day delivery is available on many products. Andrew Richardson, who represents Faital Pro in the UK was on the stand for the duration of the show, and Flavio Naggi popped over from Italy for the day on Monday. plasa 3

 

As a significant user of Faital Pro, Shermann manufacturing joined us on the stand, with a mini-selection of their products. The speakers at the front of the stand were painted in the colours of the Italian Flag to represent the link with Faital Pro. plasa_1

 

Having recently taken on distribution of Oberton, this year was our first year exhibiting this brand. Although somewhat unheard of in the UK, interest is growing rapidly in this european built brand thanks to their attention to detail with regard to engineering.Oberton have finely tuned  many of their drivers for optimum performance in horn loaded enclosures.With great specs, and keen prices, Oberton are set to give some of the old faithfuls a run for their money.  15pd600

 

We’ve been distributing P-Audio for a few years now,  so we included a selection of products to exhibit. P-Audio offers a wide range of products suitable many applications and budgets.As one of the world’s biggest OEM manufacturers, you may well have used P-Audio without even knowing it.

With our extensive stock holding, we are now able to distribute across much of Western Europe, including France, Spain, Ireland, Holland, Belgium and Denmark.

BPM/PRO 2014

We finished off a busy summer with the BPM/PRO show at the NEC in Birmingham, which ran from the 13th – 15th September 2014. It was great to see so many of our customers and business partners at the show, for those of you who couldn’t make it, or  just need a little reminder, here’s a few photos from the show. Our modular stand might look familiar, we used parts of it at BPM and PLASA in 2013, we’ve added, modified and finished with a fresh coat of TuffCab paint for 2014, giving it a new look. A few hours of screwing, bolting, sticking and tweaking and we had a display stand ready to go:

STAND BUILD:

We had a steady flow of visitors throughout the weekend

bpm_stand3

Of particular interest was one of the new brands we are distributing in the UK: Oberton, whose range include some specialist products optimised for horn-loaded applications

Featured brand: Volt loudspeakers

We teamed up with Volt this year, their first trade show in many years. Cat (David Lyth’s daughter) and her husband Steve are taking a very active role in the business, and this year has seen a few changes, starting with a new website, new company branding, and a new price structure.

The demonstration attracted a lot of interest, and educated many people on the importance of heat management within a loudspeaker. Excessive heat is the most common cause of failure in loudspeakers, managing the heat significantly improves long term  reliability.

 

Featured brand: PKN

With high power amplifiers, up to 40kw, in a compact 1U package, we felt it was high time more of you in the UK knew about these little beauties. Peter Papp, PKN’s chief engineer and designer came along this year to meet some UK users, and to pass on some of his vast knowledge to us.

Volt Loudspeakers – Unique British Built Speakers

Volt Logo 2014

 

Synonymous with  unparalleled innovation, quality and resilience, Volt Loudspeakers can be heard in some of the planet’s most prestigious recording studios and venues. Abbey Road, BBC’s Maida Vale and The Royal Opera House to name a few. Consequently, Volt loudspeakers have been used in the recording of countless albums and soundtracks that have shaped the face of popular music today; Stevie Wonder, Prince, Kraftwerk, Coldplay to name a few.

RVCXD3153_1_angledSince it’s foundation in 1978, Volt’s philosophy has remained simple: ‘Music is a universal language and we believe that it should be translated from musician to listener as honestly as possible. Therefore, the performance and quality of all our products must be state of the art.’ In order to achieve this Volt have set themselves apart from other manufacturers through their commitment to innovative product design.

Apart from endless customised and highly bespoke projects, David Lyth, Volt’s founder designed the Volt Radial which helps overcome the main performance barrier that has increasingly affected high power loudspeakers: HEAT

Cone loudspeakers are in fact very inefficient, with even the best transducers only converting around 5% of the electrical energy supplied into sound, the majority of the remainder is converted into heat. This wouldn’t be a concern, except for the fact that most voice coils are made from copper or aluminium, both of which have a positive temperature co-efficient of around 0.4% per °C. What’s the significance of that? I’m sure you will have heard of superconductors, which operate at extremely low temperatures in order to try to reduce and minimise resistance.  Loudspeaker voice coils  unfortunately work in the opposite direction: as the temperature increases, the resistance increases. Over the years loudspeaker coil technology has advanced, and a modern state of the art voice coil is designed to withstand extremely high temperatures operating at up to 3000C when driven hard. A temperature coefficient of 0.4% may sound insignificant,  but at only 2300C the voice coil resistance has almost doubled which causes the voice coil impedance to increase accordingly. Some simple maths and you can quickly see that the increase in temperature  can make your 8 ohm speaker behave like a 16 ohm speaker, which will cause your driver to be operating at significantly lower power than you might have thought, contributing to what is known as Power Compression.

Power compression is the little bugbear that can upset your best laid plans, and give you reason to throw the manufacturer’s specifications out the window. Power Compression results in a loss of sound output, and heat in the voice coil plays a major part in power compression, so reducing this heat is a key factor in reducing power compression. Many manufacturers choose to ignore power compression, some actively avoid specifying it or even mentioning it.

RV4504_aVolt have taken the opposite approach; actively tackling power compression, resulting in a key feature of Volt Loudspeaker design: Radial Technology – a cooling concept based around a unique chassis design that allows exceptional power handling and reliability.

It’s not by chance that David stumbled across this, now patented, design idea. He conducted experiments to reduce voice coil temperature by ducting the heat out of the driver and cabinet into cool air using a heatsink. This led to the eureka moment of of using a front mounted chassis as the heatsink thus killing two birds with one stone!

Whilst many conventional loudspeakers may appear to have a similar specification on paper, their performance can deteriorate dramatically after just a couple hours of use due to the detrimental heating of the voice coil. Power compression will cause the volume to drop, and if you have sufficient voltage headroom in your amplifier system, you may be tempted to turn your amps up, whilst this may initially give you a slight increase in volume, ultimately it will just cause more heat to be produced, and even more power compression – ultimately leading to driver failure.

Power Compression can also have a very noticeable negative effect on sound quality, common symptons being suppression of the mid output and misaligned bass enclosure tuning, resulting in boomy bass and muffled mids.

Whilst he’s reluctant to admit it, David has over has over 40 years experience in the industry. Prior to starting Volt, David worked for Gale Electronics, Martin Audio and Sanyo. Volt’s first premises were also in London’s old EMI buildings – so it grew within the finest traditions of the British audio industry.

Now based in a rural location in Dorset, Volt Loudspeakers are moving into an exciting new era. With  a ‘no compromise’ attitude on quality, all Volt Loudspeakers are hand built in the UK using precision manufactured components.

In 2013, David relinquished control of the management of the business and handed it down to his daughter Cat, creating an opportunity for the next generation of British speaker building to grow and flourish.

Volt_Music_messe_medium

Unsurprisingly Cat has grown up against a backdrop of loud music, she attended her first industry trade show with her Father aged just 6 months! In later years, she has worked at Volt in various roles from production, administration and on exhibition stands. Consequently, Cat appreciates the importance of continuing to hand build all of Volt’s speakers and inductors. She knows that Volt’s meticulous approach to sourcing materials and using leading technologies is fundamental in offering the superior sound performance and high reliability that the company is so respected for.

Working alongside Cat is her fiance Steve, who is from an audiovisual and electronics background with over ten years experience in building and installing sound systems in a wide range of locations spanning clubs, festivals and corporate environments. A technically minded chap, Steve is now working under David’s wing to ensure the smooth running of speaker and inductor production at Volt and will be working closely with David to develop and launch new products and refine production systems.

 

Volt are launching their new website in March 2014 so we’d encourage you to have a look at their product range, patented Radial Technology and for new designs in the not too distant future. http://www.voltloudspeakers.co.uk/

Blue Aran will be taking stock of demo units in the coming months, so if you want to compare your existing loudspeakers to some Volt Loudspeakers, get in touch and we’ll arrange a testing session for you to pop down and see us.

Tuff Cab Loudspeaker Paint

tuffcab_heading2

Tuff Cab, our very own specialist loudspeaker paint, is an enormously versatile, easy to apply water-based acrylic blend. Hard-wearing, it is ideal for finishing your newly-built speaker cabs to give them an easily-maintained professional look, or for sprucing up your trusty warhorses to have them look like they just left the showroom.

A custom-formulated viscous mixture, Tuff Cab lends itself to a huge range of different surface finished depending on how it is applied, so here’s our handy guide for how to quickly and easily obtain the best results.

1) Surface Preparation:

Cab refurbishment - before painting

Cab refurbishment – before painting

As with absolutely any surface finish, proper preparation of the surface to be painted is absolutely essential prior to painting. Tuff Cab is designed for optimum adhesion to bare timber, and as a water-based mixture it’s important to make sure that there are no traces of oil or grease present. A little bit of light sanding is usually advisable to remove surface contamination; bear in mind that this will leave traces of dust behind, which you will need to remove by wiping the surface with a clean, slightly damp cloth. No primer is required before applying the Tuff Cab – best results are achieved painting directly onto bare wood. Some people like to use a watered down mix of Tuff Cab (approx 50:50 with tap water) as a primer/base coat, and apply this by spraying or rolling with a non-textured roller, this helps the paint key into the surface, but is not essential.

Although designed primarily for application to timber, Tuff Cab does offer good adhesion to a range of other porous materials, and works well with MDF and natural wood. ABS, polypropylene and other plastics do not offer a suitable surface for Tuff Cab, so we not advise to attempt refinishing such items in this way. MDF and plywood will readily accept Tuff Cab, some resin, epoxy, plastic and solvent-based wood fillers will impair adhesion over the filled area.

handy hint Handy Hint: If you do use plastic/solvented fillers, a thin coat of PVA glue can be brushed over the affected zone, this will help seal any solvents, and prime the surface, significantly improving  adhesion in these problem areas.  

However we recommend avoiding the use of this type of filler if at all possible. For covering screw holes, we have had good results from mixing standard wood filler with PVA glue. The glue hardens the filler, making it less prone to flaking, and seals it at the same time. Some paint finishes (particularly two-pack polyester paints) will not provide good adhesion for Tuff Cab, and it is advisable to sand these down to bare wood prior to painting. Any cellulose base paint must be completely removed prior to applying Tuff Cab.

2) Painting:

Tuff Cab’s viscous finish is specifically designed for roller application, ideal for a fast, easy, professional results. Other methods of application (such as brush or spray) are also possible, but these may not yield optimum results, and can require specialist equipment and considerable experimentation to achieve an acceptable finish. For this reason, we recommend roller application.

Tuff Cab is best applied at room temperature – avoid painting in an exceptionally cool environment (below 12°C) as the drying time increases significantly, excessive temperatures (above 25°C) can result in the Tuff Cab surface drying too quickly. Within this temperature range, the first coat will usually dry in around 30-60 minutes (dependent on  application thickness and temperature – in a cool environment, up to 2-4 hours is not unknown), subsequent coats will take a little longer. A second heavy, textured coat may take up to 24 hours to fully dry in cool conditions.

Painting in the heat: On a hot summer’s day it may be very tempting to get all your speakers out in the garden and give them a fresh coat of paint. We advise you try to pick a slightly cooler day. Summer heat with temperatures around 30°C, the paint can dry in as little as 10-15 minutes, sometimes making it difficult to finish a panel with an even coat, rapid drying time like this will tend to increase the possibility of roller marks from the edges of the roller.  With the paint drying whilst you are rolling it on, it is possible also for the texture to become a little ‘spiky’ making the surface feel very rough, almost like sandpaper.

Honeycomb Roller TUFFROLLER01

Honeycomb Roller TUFFROLLER01

For a textured finish, Tuff Cab can be applied using a honeycomb roller.  The 4″ roller is ideal for small jobs, as it takes minimal paint to wet the roller, and you can dip the roller straight into the tin, no need for a paint tray!

We recommend applying a relatively heavy coat and then rolling in both directions to evenly distribute the paint. Less rolling will give a more pronounced stippled finish, more thorough rolling will gradually flatten the texture and yield a more moderate texture finish. When using the textured roller it is best to roll steadily and smoothly, applying excessive pressure is likely to leave marks at the edges of the roller, and rolling too fast can cause a rough spiky texture. Once the paint is spread across a panel, gradually reduce the pressure on the roller, so that the last few rolls are very gently, almost like you are pulling the roller along with your fingertips.

For larger speakers and panels, you may find it is quicker to simply pour on a small amount of Tuffcab, and use a 9″ textured roller to quickly spread the paint across the panel. With a 9″ roller you can often coat a panel in less than half the time of a 4″ roller.

Use of both 4″ and 9″ rollers together allows quick coverage of large panels, and the ability to work around corners, edges and ports.

If you prefer a smoother finish this can be achieved by applying tuffcab with a standard fluffy polyamide pile roller.

handy hintPractise first: Before you start refurbishing old speakers, or painting new speakers, we strongly recommend a practise run on an offcut. Slightly different textures can be obtained by varying the amount of paint applied, the type of roller, the speed of rolling and  to what extent you repeat the rolling to flat the paint.

Two to three coats of Tuff Cab are usually enough to provide adequate protection and a suitable surface finish for most applications, and depending on the temperature, you can apply this within a 24 hour period and have a ‘touch-dry’ finish. When touch-dry it is possible to handle speakers and move them around, but we do not recommend using them straight away, it can take up to a week for the paint to fully cure and harden, longer in cool conditions.

If you need the paint to cure quicker, once it is touch-dry you can use an infra-red heater, such as an electric patio heater. Do not use a heater  on freshly painted surfaces as may dry the paint too quickly, causing cracks to appear in the surface. Avoid positioning the heater too close to speaker cabinets, and ensure you follow the manufacturers recommended minimum operating distance for your heater.

Once fully cured, your speakers will be road-ready.

3) Cleaning and Storage:

Whilst wet, Tuff Cab is water-soluble, and your painting equipment (along with any unwanted paint splashes and spillages) can be cleaned with cold tap water; simply rinse under running cold water until the water runs clear and the equipment is clean. As with any water-based paint, ensure that Tuff Cab is not exposed to extremes of temperature in storage – it must be stored no lower than 5°C, and preferably no higher than 25°C.

Storage below  5°C can damage the chemical structure, preventing the paint from curing and adhering when used. If damaged in this way, the paint will appear to dry as normal, but it bonding properties will have been severely impaired and the paint may peel off.

Long term storage  outside of recommended temperature range can adversely affect the product structure, composition and performance. Product must be kept in a tightly sealed container, stored out of direct sunlight. Tuff Cab has a recommended shelf life of 6 months, but if kept at standard room temperature, the shelf life can be up to 18 months. In part-used containers of Tuff Cab, spraying a very light misting of water over the top of the Tuff Cab in the container prior to re-sealing for storage can help alleviate skinning-over. If you find you have applied a little too much water, just pour it out or mix it back into the paint before use. Repeated addition of water will affect the viscosity, and the final finish, so minimal water should be used for consistent results.

handy hintHandy Hint: You dont need to wash your roller our between coats, just wrap it in a plastic bag, or cling film to avoid exposure to the air, and then take the plastic off when doing the next coat – the paint and roller will stay fresh for up to 3-4 days under the plastic saving you cleanup time!

PKN Audio Amplifiers

PKN Audio High Power Amplifiers

PKN Controls is a Hungarian company located in Szekesfehervar. Founded by Peter Papp, Roland Nagy and Gergely Kiss in 2001 to design and manufacture high quality and high power amplifiers for live concerts, theatres, clubs and stadiums, they use exclusive lightweight high current technology from their background in industrial power control. The evolution of their product line has been remarkable since the introduction of the first XD Series (XD-1600, XD-2500,XD-3200) in 2001.

Their winning combination of high output, extreme portability and industrial levels of build quality giving more than the reliability needed for tour grade applications found these amplifiers a strong customer base across Central Europe. Expanding on this success, PKN developed the XD and XE Series, introducing them to the world at the SIB2006 exhibition (Rimini, Italy) in 2006. Since then they began establishing distribution channels across the global marketplace.

PKN continually listen to feedback from customers and distributors worldwide, and always place these requests at the heart of their research and development process.  Some of their developments include the truly astonishing 3PHASE Series which can deliver up to 40000W (yes, that’s forty thousand Watts) – of power output from a single rack unit weighing in at under 14kg.  With the option of 4 outputs at  10000W or 2 outputs at 20000W, the challenge is going to be finding speakers man enough to handle the power.

XD SeriesThe XD Series offers an extremely affordable and portable solution for high power amplifier requirements.  The XD2500, XD4000 and XD6000 weigh in at 8kgs, 9kgs and 9.5kgs respectively, making it possible to rack up seemingly limitless power effortlessly. No more giant back-breaking racks to hump around; with PKN, you can easily run a 20kW system with just a few amps in a small rack that’s a one man lift. The XD Series includes comprehensive protection circuitry; covering Short Circuit, Overload, Low Impedance, Thermal and DC Fault conditions.

XE SeriesThe XE Series offers additional features for the more demanding user, all models in the series have LCD graphic display units and two rotary jog controls for direct control of the system parameters. Particularly useful for larger, more complex installations, the devices have internal webserver software which facilitates remote operation via normal internet browser (JAVA based) or with dedicated PKNC control software. Simply connect via standard ethernet and you can remotely monitor the amplifiers status and adjust limiters and volumes.

To meet the increasing user demand for extreme power in sub-bass applications, PKN Audio developed two new models in 2013, available  as part of the Universal Line Touring Amplifier Range , the XD10000U and XE10000U are welcome additions to the range, offering power output up to 6,500W per channel. Both feature excellent dynamic response, improved damping factor, and new digital controlled high-frequency single-stage resonant power supply with high power factor operation. As part of the Universal Line, they have exceptional AC line range and ruggedness against line disturbances. Operating range is from 64Vac to 300Vac with inbuilt protection against accidental connection of up to 560Vac. Power control is paramount in all XE Series amplifiers, with Zero inrush current, programmable wake-up sequence(s) and mains current limiter help to operate systems on limited resources.

The new XE Series firmware also includes a digital limiter which can be programmed in Watts to help protect your speakers against excessive power.

So how do they pack so much power handling into such a small amplifier?

Looking at the specifications, you might believe they had made use of TARDIS technology, and actually made the amplifier bigger on the inside. Risking the possibility of letting the magic dust escape out of the amplifier, we popped the lid off one of them to take a peek inside:

Turns out it’s just some clever technology, secret custom built high quality components, and a little Hungarian magic.

Arriving in the UK In January 2014, we are looking forward to road testing these pint-sized power stations.
