P.Audio System debuted a comprehensive range of high-frequency transducers at this year's NAMM2008 Convention. In addition to HF compression drivers, the company offers a comprehensive range of high-performance low-frequency component drivers and HF horns.
The Driver Series of HF compression drivers includes the BM-D Series II and PreNeo Series. "The new PreNeo compression drivers feature our recently developed Cavity Resonance Technology™," states company managing director Howard Chen. "Cavity Resonance Technology - CRT - is a unique combination of techniques that act to substantially reduce the resonance found under the compression-driver suspension, and results in an improved mid-band time-domain response and reduced mid-band distortion. The result is dramatically improved vocal clarity and intelligibility."
The PA Series is comprised of four models: the PreNeo-750N and PreNeo-740N high-output compression drivers with large-format, titanium-based diaphragm assemblies mated to a closely-spaced circumferential phase plug geometry - the -750N features a 2-inch/50 mm throat exit while the -740N features a 1.4-inch/35.5 mm throat exit; the PreNeo-450N high-output compression driver with a 1.0-inch/25.4 mm throat exit and CRT technology for improved time domain response and reduced distortion through the critical upper vocal range; and the PreNeo-340S high-output compression driver with a small-format, titanium-based diaphragm assembly mated to a closely-spaced circumferential phase plug geometry plus a 1.0-inch/25.4 mm throat exit.
The advanced PreNeo Series utilizes Neodymium-based permanent magnetics that ensure an excellent performance-to-weight ratio. "Neodymium-Iron-Boron provides an extremely high energy product and is also very lightweight," Chen continues. This combination allows Neo-based compression driver designs to combine both high-output/high-quality response with a very lightweight design; the results are said to be ideal for touring audio and lightweight suspended systems found in permanent- installation systems. Diaphragm assemblies are made of high-strength, pure titanium with geometries optimized to reduce modal patterns in the system. Each diaphragm is closely spaced to the phase plug to insure consistent high-frequency response.
The BM-D Series comprises seven models with Ferrite-based permanent magnetic systems: the BM-D750 and BM-D740 are high-output compression drivers with large-format titanium-based diaphragm assemblies mated to a closely-spaced circumferential phase plug geometry and rectangular geometry, with high-temperature aluminum voice coils to ensure extended high-frequency response - the BM-D750 features a 2-inch/50 mm throat exit while the -D740 feature a 1.4-inch/35.5 mm throat exit; the BM-D450 and BM-D450S high-output compression drivers with 1-inch/50 mm throat exits and CRT technology to improve time-domain response and reduce distortion through the critical upper vocal range; the BM-D440 and BM-D440S high-output compression drivers with 1-inch/50 mm throat exits and CRT technology to improve both time-domain response and reduce distortion in the 1.5 to 5 kHz range; and the BM-D340S high-output compression driver with a small-format, titanium-based diaphragm assembly mated to a closely-spaced circumferential phase plug geometry and a 1.0-inch/25.4 mm throat exit for screw/threaded-on horns.
"All our state-of-the-art compression drivers," Chen concludes, "are designed to meet the exacting performance parameters expected for applications ranging from touring systems to large format fixed installations."
