Model IWTS-28 SUB
In-Wall Subwoofer
Thank you for purchasing Atlantic Technology products. Our speaker systems have been designed to deliver exceptional sound and value. We hope
you like what you hear from them, and are happy with your decision to

Please take a few moments to read these instructions. They’re intended not
only to tell you how to mount the speakers, but how to get the best performance from them.
Important Considerations Before
Installation
Recommended Wire Sizes
The longer the wire run, the heavier the wire should be. Use the following
recommendations as a guide for your installation. And if you’re in doubt,
remember that it never hurts to get the next heavier grade of wire. Also note
that lower gauge numbers equal heavier wire sizes.
Wire Run Wire Gauge:
<15 ft. 16 ga.
15 to 30 ft. 14 ga.
>30 to 50 ft. 12 ga.

Speaker Placement
Location Considerations
Choosing the location for the subwoofer is a very important consideration.
Since the IWTS-28 SUB can't easily be moved once it’s installed (!), very
careful consideration should be given to its placement. In general, the cleanest and most articulate delivery of bass energy into the room occurs when
the subwoofer is placed asymmetrically with respect to the room’s dimensions. (see fig. 1). Such placement generally results in the best overall balance of bass impact vs. ‘one-note boom.’
Figure 1 – Asymmetrical Placement
If you are using two 28 SUB modules, follow the same advice: locate them
asymmetrically within the room (i.e. one near a corner, one towards the
middle of a wall) to smooth out the bass and minimize random standing
wave patterns. (see fig. 2)
