“Large”. Selecting the size accordingly will ensure bass goes to most appropriate speakers, and use the subwoofer correctly too. Also, is your subwoofer turned “ON”? We don’t mean “is your subwoofer amplifier on?” that’ll be important later too! but rather, is your receiver send- ing a bass signal to your sub amp? This can only happen if you say “Yes” or “ON” to the “Subwoofer” setting of any typical Dolby Digi- tal/DTS capable receiver

significantly lower your sub’s volume control. This helps keep input distor- tion to a minimum, however you should not be set much lower than -5dB recommended earlier, some adjustment room is needed to tweak down the road. If your subwoofer reading is still too high then turn down the sub’s amp volume a little with each run

Phase. Think of bass waves as conflicting or enhancing each other, depending on the timing of their arrival at your listening location either together, or not. Since some of your HT bass might come from main, center and/or surround speakers, as well as your sub, getting these bass wave forms to arrive in a com- plementary, enhancing fashion is the difficult job of the phase knob. Essen- tially this control varies the timing of the bass waves coming from the sub. You can tweak this endlessly and not hear much difference but don’t despair, the effect of bass cancellation will vary by volume and frequency in your room, and no one setting is likely to ever be “perfect”. One simple technique to opti- mize phase is to find a nice “bassy” loop such as the menu of “Godzilla” and measure the loop’s bass response at various bass SPL peaks. As the loop runs, you can make gradual changes to the phase knob. Where you see the most re- sponse on a given bass passage is the phase setting providing the least bass cancellation in your room for the frequencies of the demo loop you chose
