IWTS-28 SUB In-Wall Subwoofer

Connecting the IWTS-28 SUB to Your System

The IWTS-28 SUB may be used as a passive bass module to reinforce the bass from the left/right front speakers in your system,or it may be powered by an external amplifier (such as Atlantic’s SA-180 mono bloc amplifier).

To Connect as a Powered Subwoofer:

Leaving the jumpers in place,connect the speaker wires from the SA-180 to one black terminal and one red terminal on the 28 SUB. Make sure the 28 SUB’s front-panel low-pass switch is in the off position (see fig. 3).

To Connect as a Passive Bass Module:

Remove the jumpers from the 28 SUB’s terminals (see fig. 4). Run speaker wires from the receiver’s front left speaker terminals to one set of termi- nals on the 28 SUB. Run another set to the other set of terminals on the 28 SUB. (see fig. 5) It does not matter which woofer on the 28 SUB is con- sidered‘right’ or‘left,’ since bass is generally recorded in mono, and is non- directional anyway. Be careful to observe consistent polarity between the two woofers,and between the woofers and front L/R speakers.All reds and blacks should be consistent.

Be sure to switch the 28 SUB’s front panel low-pass switch to“on.” This will filter out any signal above around 200 Hz from reaching the 28 SUB module, and ensures that only the non-directional lower frequencies are being fed to the SUB, thus preserving your system’s front-channel sonic imaging.

Important note: Each individual woofer in the 28 SUB is 8 ohms; when connecting them in parallel with your front L/R speakers (as you do when using the 28 SUB passively), the front L/R speakers need to also be 8 ohms minimum, so that their combined paralleled imped- ance does not fall below 4 ohms. Consult your receiver’s owner’s manual for more information on its impedance drive capability.
