Product Description
Manufacturer Part Number: CD-151Fe/PT
The Beyma CD-151Fe/PT is a next-generation 1" compression driver designed for high-performance professional audio applications requiring extended frequency response, high power handling, and low distortion. Its advanced design and proprietary technologies make it suitable for use in high-quality sound reinforcement systems, line arrays, and other demanding audio setups.
Key Features:
Beyma CD-151Fe/PT 1" Polymer Diaphragm Compression Driver 8 Ohm 2/3-Bolt
The CD-151Fe/PT's substantial power handling and high sensitivity enable it to deliver clear and dynamic high-frequency output, making it ideal for demanding audio applications. The integration of Deplocex technology enhances thermal dissipation, reducing power compression and allowing for consistent performance during extended use. VPEQ® technology ensures a linear frequency response, contributing to accurate sound reproduction. The 1.5" copper-clad aluminum voice coil with Kapton former provides durability and reliability under high-power conditions. The advanced polyester annular ring diaphragm, optimized using finite element modeling (F.E.M.), offers an extended frequency response with minimized resonances, resulting in a smooth and natural sound. The inclusion of a copper shorting cap reduces distortion and linearizes inductance, further improving sound quality. The F.E.M.-optimized ceramic magnetic circuit enhances overall efficiency and performance. Designed for high-quality sound reinforcement systems and line arrays, this compression driver delivers exceptional performance for professional audio setups.
In high-performance audio applications, achieving the required magnetic force (Bl) and sound pressure levels (SPL) often involves using single-layer edgewound wire or double-layer round wire coils. However, the double-layer configuration has a drawback: one of the coil layers cannot dissipate heat as effectively as the other. Additionally, flat wire designs typically feature shorter magnetic gaps, which limit power handling and lead to power compression at lower voltages.
Beyma's DEPLOCEX technology addresses these challenges by maximizing the surface area of the coil and magnetic gap, enhancing heat dissipation through radiation while maintaining the same Bl and final SPL. This design improves thermal transmission along the entire coil length in contact with the iron.
As a result, coil temperature is reduced by 30%, minimizing the effects of power compression. This advancement enables high-frequency drivers to achieve over 15% more power.
Any sound transmission channel has its own eigenmodes. For example, in a tube closed at one end by a diaphragm and open at the other, these modes can be easily calculated. However, in compression driver ducts, the situation is much more complex. These modes cause peaks and valleys that degrade the frequency response.
After extensive research, simulations, and testing, Beyma's R&D team has developed a unique solution to enhance the frequency response of our compression drivers.
The principle behind solving this complex problem is straightforward. By varying the shape of the duct, we can linearize the system's response and achieve a better transfer function.
Adjusting the tube's width and designing an organic shape based on various mathematical functions create significant variations in sound pressure levels at specific frequencies, resulting in a much improved transient response.
