The P Audio philosophy of continuous improvement requires constant research & development efforts aimed at upgrading critical performance parameters.
The BM-D 446 high performance compression driver presents many improvements in both amplitude & time domain response.
These technological advances represent additional improvements in the very successful BM-D series of high performance compression drivers.
The BM-D 446 magnet gap geometry has been redesigned to improve both the time domain & amplitude domain response in the critical upper vocal range between1kHz & 3kHz.
These performance improvements translate into superior vocal range intelligibility & clarity.
Additional improvements in the phase plug spacing & rear volume have yielded substantial improvements in the10kHz range that translate into superior ultra high frequency accuracy.
The BM-D 446 is ideal for use in high output two way professional audio system designs.
The driver may be integrated into systems utilizing 8 inch (203 mm) high output woofer or larger & is ideal for very high performance systems using 12 inch (305 mm) & 15 inch (381mm) low frequency sections.
The rated frequency range of the BM-D 446 driver is 1kHz to 20kHz.
Passive crossovers w/2nd order (12dB/Oct) or higher slopes will produce ideal band limiting & crossover frequencies of higher then 1kHz are recommended for very high output designs.
The BM-D 446 utilizes a 1.75 inch (44.5mm) diaphragm assembly of commercially pure titanium.
The diaphragm assembly features P Audio’s ultra high thermal stability adhesives & is coupled to a precision voice coil assembly designed to maximize conversion efficiency.
The circumferential slot phase plug provides very wide bandwidth coupling of the diaphragm to the 1 inch (25.4mm) industry standard exit.
Close spacing of the diaphragm & phase plug insure excellent bandwidth & acoustic damping.
The mounting geometry is a standard bolt on style that is compatible w/P Audio & many other standard high frequency horns & wave guides.
The BM-D 446 is a Ferrite based permanent magnetic system that has been computer optimized to yield maximum magnetic energy & conversion efficiency.
Finite Element Modeling has produced a very high magnetic energy field while maintaining a very compact geometry & reduced weight.
