System Configurations
The SA-380 amplifier is a mono-block amplifier, which
drives a single IWTS-8e SUB woofer module. Any
number of amplifier/woofer modules may be used,
depending on the system requirements. In small- to
medium-sized rooms, it’s likely that a single amp/
woofer module will be all that’s needed for outstanding
bass. For larger spaces (or when extremely loud bass
reproduction is a necessity), two or more amplifier/
woofer modules can be used.
Subwoofer Features
The woofer module consists of two very powerful 8-inch
drivers specially designed to deliver substantial bass
energy from the in-wall enclosure. Because they’re only
8 inches in diameter, their cones respond very quickly to
the amplifier’s signal.
In addition, the baffle is coated with a special compound
called RDT™ (Resonance Dampening Treatment),
designed to suppress unwanted baffle resonances and
maximize inner bass detail and articulation. The result
is very “fast” bass response without boom or overhang:
Music is taut and precise; special effects are powerful
and room-filling.

The woofer module is shown in its
dedicated in-wall enclosure. Once
it’s installed within the wall (new
construction only) all you see is
a gently curved perforated metal
grille that projects into the room
approximately 1½ inches. The
grille and the trim ring around the
woofer module are supplied in a
matte white primer finish that can
be used as is or painted to match
the surrounding wall surface.
