Beyma Unveils Next-Gen Compression Drivers: Limitless Audio Possibilities!

Beyma Unveils Next-Gen Compression Drivers: Limitless Audio Possibilities!

Beyma, the leading name in audio innovation, is proud to introduce its latest generation of compression drivers, pushing the boundaries of sound reproduction to unprecedented heights. This cutting-edge series encompasses 12 new models, offering a versatile selection that caters to a wide range of audio needs. Let’s delve into the key features and technologies that make these compression drivers stand out from the crowd.

Introducing the Models:

  • CD314: Throat Diameter – 1.4 in | Voice Coil Diameter – 3 in
  • CD2514: Throat Diameter – 1.4 in | Voice Coil Diameter – 2.5 in
  • CD171: Throat Diameter – 1 in | Voice Coil Diameter – 1.75 in
  • CD151: Throat Diameter – 1 in | Voice Coil Diameter – 1.5 in

Precise Sound Tailoring:
One of the standout features of Beyma’s new compression drivers is the ability to tailor the sound to perfection. With three diaphragm material options – Titanium, High Temperature Polymer, and Advanced Polyester – users can achieve distinct SPL responses, timbre, and sonic properties. This flexibility empowers system designers to create audio experiences that precisely match their acoustic targets and application requirements.

VPEQ Technology: Equalization of the Frequency Response
To combat inherent frequency response irregularities caused by transmission channels’ eigenmodes, Beyma’s Research and Development team has developed VPEQ technology. By carefully varying the duct shape, the system’s frequency response is linearized, resulting in a remarkable improvement in sound transfer. The organic shape, designed according to different mathematical functions, ensures a significant variation in sound pressure level for calculated frequencies, leading to a superior transient response. VPEQ optimizes the compression driver’s performance, enhancing the overall sound quality.

DEPLOCEX Technology: Improved Thermal Dissipation
For audio professionals seeking exceptional performance, thermal dissipation is a critical aspect. Traditional designs often face challenges in handling high SPLs while effectively dissipating heat. With DEPLOCEX technology, Beyma revolutionizes thermal dissipation in compression drivers. By maximizing the surface area of the coil and magnetic gap, the configuration enhances heat dissipation through radiation while maintaining the necessary Bl and final SPL. This groundbreaking approach reduces the coil’s temperature by up to 30%, minimizing the impact of power compression and delivering high-frequency drivers that are more than 15% more powerful. DEPLOCEX ensures reliable and consistent performance even under demanding conditions.

Unleash Your Creativity:
With the combination of VPEQ and DEPLOCEX technologies, Beyma’s new compression drivers offer unparalleled audio design possibilities. Musicians, sound engineers, and audio enthusiasts can now achieve extraordinary sound precision and clarity in their setups. Whether you’re working on professional sound systems, studio monitors, or any high-fidelity audio applications, Beyma’s next-gen compression drivers are your gateway to limitless audio possibilities.

Experience the future of audio technology with Beyma’s groundbreaking compression drivers. Upgrade your sound system today and explore the world of sound perfection.

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).

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.
