The P Audio has redefined its BM series of compression drivers. The BMD450
is a state of the art high output compression driver. New developments
P Audio Research and Development have produced new levels of
performance. State of the art manufacturing methods insure extremely
reliable and consistent designs.
The new BM-D450 driver utilizes the recently developed CRT™ technology
to substantially improve both the time domain response and reduce
distortion through the critical upper vocal range (1.5kHz to 5kHz). This
new technology, called Cavity Resonance Technology ™ (CRT) acts to
acoustically minimize the cavity found under all suspension driver suspension
elements. By employing CRT technology, P Audio engineers have
been able to greatly improve the vocal accuracy in the frequency range
where vocal intelligibility is located. Magnetic fluid has also been added
to increase thermal transfer and mechanical damping. These changes to
the diaphragm and magnet structure assembly have also increased the
sound pressure levels and smoothed the response between 10kHz and
20kHz. The result is a more accurate system, particularly for vocal range
program material.
The BM-D450 is a medium format titanium based diaphragm assembly
mated to a close spaced circumferential phase plug geometry. The voice
coil is a rectangular geometry, high temperature aluminum to insure extended
high frequency response. This diaphragm geometry is ideally suited
for foreground/background high performance pa systems.
The 1.0 inch (25.4mm) throat exit makes the 450 an excellent choice for
extended bandwidth and ultra high frequency applications such as three
way designs. The BM-D450 is ideally suited for line array applications or
other applications where a mid bass horn or direct radiator driver is also
used. This medium format throat and medium format diaphragm insures
wide dispersion at very high frequencies and is an excellent choice for
three way systems or medium power two way designs. The 1.0 inch throat
is compatible with a variety of P Audio horns and also compatible with industry
standard 1.0 inch bolt on horns.
The Ferrite based permanent magnetic system produces a very high efficiency
and value. This makes the BM-D450 ideal for professional applications
as well as fixed installation systems. The large format Ferrite permanent
magnet produces a very high conversion efficiency. |
