Instruction Guide and Owner’s Manual
Description
TRUAUDIO’s in-wall subwoofer was designed to deliver deep, tight and powerful low frequency reproduction
but still fits into a standard 2 x 4 wall depth. Finally you can get good bass without the big obstructive cabinet of
standard subwoofers. This model is ideal for an entertainment room or dedicated home theater. Then, in
combination with any of our in-wall/ in-ceiling speakers, this sub-woofer is the perfect component for any Hi-Fi
system. Front mounted controls make it easy to adjust the sound for any room.
These models use awesome bass drivers that allows for very low distortion and powerful reproduction of music
and video. Our driver’s incorporate large magnets and voice coils which allows no distortion at high volumes.
Every subwoofer driver is tested to make sure that it holds up to TRUAUDIO strict specifications.
Please note: The SUB-88A must only be installed and used in the custom MDF in-wall
enclosure, model EL-SUB88
Speaker Cable Recommendation
Speaker cable recommendation, When choosing the wire gauge take in consideration of the output power of the
amp (for this in-wall sub, it should be at least 200 watts) and the length of the cable between the amplifier and
the subwoofer. The longer the wire run, the heavy wire gauge needed. We strongly recommend that you use a
high-quality speaker wire between the amplifier and the subwoofer. For this model use at least 14 gauge for runs
up to 80 feet. If your run is longer than 80 feet, you should consider using 12 gauge. Remember that the wire
increases in size as the gauge number decreases.
Caution, before installation of the subwoofer
The MDF in-wall enclosure is designed for new construction and remodels. This enclosure must be installed
before the drywall or wallboard. It should to be placed vertically between two 2X4’s. This enclosure is build to
provide the perfect air space needed for the SUB-88A. The SUB-88A must be used with the EL-SUB88 cabinet
to insure proper operation. The MDF cabinet will prevent some of the low bass frequencies from adjacent rooms
but because these are true, high-powered subwoofers.
There will be some sound transmitted through the wall (as
with all good in-wall subs).
