Speaker Placement Instruction Manual Location Considerations Choosing the location for the subwoofer is a very important consideration. Since the IW-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 and is located along the same wall as the left and right speakers.
Connections IW-28 SUB In-Wall Subwoofer Connecting the IW-28 SUB to Your System WARNING: To prevent risk of electrical shock or damage to your equipment, always switch off the amplifier or receiver when making any system connections. Speaker Connection It’s important to observe polarity while making speaker connections: red (+) terminals on the amplifier to red (+) on the speaker, black (–) on the amplifier to black (–) on the speaker.
Installation Instruction Manual Distributed Audio Connection How to install the IW-28 SUB with a distributed audio system is dependent upon your specific system. If your source has “sub out connection” follow the “monoblock amplifier connection” instructions. You may use a channel from your amplifier to power the subwoofer or Atlantic Technology’s SA-180 monoblock amplifier. IMPORTANT! Set the IW-28 SUB’s front-panel Low-Pass switch to the “off” position. This will bypass its crossover.
Installation IW-28 SUB In-Wall Subwoofer Installing the Speaker Assembly • If this is new construction, we strongly recommend using 5⁄8” or ¾” drywall. It’s heavier and more expensive than ½” material, but it’s far, far superior in terms of acoustic/mechanical integrity and rigidity. We also strongly recommend that the drywall be screwed to the studs every 6 inches or so, instead of the more common practice of nailing it every 12-18”.
Specifications Instruction Manual Front Panel Controls Low-Pass Control The IW-28 SUB has a front-mounted control that selects or bypasses the speaker’s built-in Low-Pass crossover. Set this to the “off” position when connected to the SA-180 or other amplifier. In this case, the receiver is used to control the low pass filtering. Set it to “on” only when using it in the “passive” mode, powered by 2 channels of amplification.
