Installing the Speaker Assembly into the Frame
Once the frame is mounted in the wall, the speaker assembly simply fits
into the frame as shown.
Use the included screws to attach the enclosure to the mounting frame.
Front Panel Controls
Low-Pass Control
The IWTS-28 SUB has a front-mounted control that
selects or bypasses the speaker’s built-in low-pass
corossover. Leave this in the off position when using the
28 SUB with an outboard amplifier and your receiver’s
low-pass crossover.
IR Knockout
There’s an IR “knockout” plug in the upper right corner
of the baffle. If you are using a multi-room control sys-
tem, you can install a standard IR receiver in the knock-
out hole.
