Model IW-28 SUB
In-Wall Thin Bezel Subwoofer
Thank you for purchasing Atlantic Technology products. Our speaker sys-
tems have been designed to deliver exceptional sound and value. We hope
you like what you hear, and are happy with your decision to buy them.
Please take a few moments to read these instructions. They’re intended not
only to tell you how to mount the speaker, but how to get the best perfor-
mance from it.
Unpacking the Speaker
Use care when unpacking the speaker. Remember to save all packing
materials until you are certain that the speaker has suffered no damage in
shipment. If you find such damage, either visible or internal, contact your
dealer immediately.
If you can do so, save the carton, packing pieces, and plastic bags that came
with your speakers. They will be useful in case you move or have to ship
your loudspeaker for any reason.
Description
The IW-28 SUB is a thin bezel, in-wall, passive subwoofer that has dual
8” long throw woofers, a ¾” reinforced MDF baffle and a switchable Low-
Pass crossover that will provide you years of enjoyment. The IW-28 SUB is
designed to be used with either a monoblock amplifier, such as our SA-180
in a home theater application or as a passive subwoofer connected in par-
allel with the L/R speaker in a traditional 2 channel audio system. It may
also be used in a distributed audio system to add dynamic range that most
people are missing in today’s whole house installations.
