This compact amplifier is ideal for a simple audiophile-grade,
subwoofer / satellite system. With the M500/3, you can drive a pair of
quality component speaker systems with plenty of clean power, while
also delivering a stout 300 W to a subwoofer system. The breakthrough
that makes this much power possible in such a small chassis is our
NexD™ switching design.
The M500/3 includes a 12 dB / octave
high-pass filter for its main channels, plus a variable slope low-pass
filter for its subwoofer channel. Both filters offer continuously
variable cutoff frequency selection from 50-500 Hz.
This marine
amplifier features white and gray powder-coat finishes, a gasketed
cover for the controls and stainless steel hardware for durability in
the marine environment.
