Recommended Sub Settings

Setting the Aperion Audio Intimus S8-APR Subwoofer

In addition to the high and low-level speaker connections on the rear of your subwoofer, you will see two round knobs and three switches. The first knob, labeled “level,” controls the subwoofer’s volume. The second knob, “crossover frequency,” sets the crossover frequency. As a starting point, set the receiver crossover at 80Hz and the subwoofer crossover between 80Hz-120Hz.

The power switch has three settings - on, off and auto. When the switch is set in the “auto” setting, it will automatically turn the sub on when a signal is present. You’ll know the subwoofer is on because the power lamp will be illuminated red (when a signal is present it turns green). The “phase” switch reverses the subwoofer’s polarity. If the distance from the sub to the listener is significantly different than the front and center speakers (>3’), try using the phase reverse switch to see if it improves the bass response.

The S8-APR has a switchable voltage control. Please be sure to select 120V for use in the USA.

The illustration to the right shows a recommended starting point for settings. You will want to adjust these based on personal preference and room dynamics.
