UltraSeries™
Subwoofer
The compact, high-power USW-1
extends the frequency range and power
bandwidth of Meyer Sound reinforcement
systems to 40Hz. Accurate and rugged,
the subwoofer consists of two 15-inch
cone drivers capable of long excursion
with extremely low distortion, housed
in a heavily braced five cubic foot vented
enclosure of multiple-ply hardwood.
Fitted with handles, the roadworthy
cabinet has a durable, textured finish and,
optionally, aircraft-style rigging pan fit-
tings for ease of installation.
The USW-1 requires a professional qual-
ity power amplifier capable of delivering
up to 400 watts into 4 ohms (this normally
corresponds to a 250 watt/8 ohm rating),
with a signal voltage gain of 20 dB (mini-
mum) to 30 dB (maximum).
