Phase Settings on SW

Evanguy2004

Hello everyone,

I now have my new Polk Audio Model PSW111 Sub Woofer rocking now that I have found the DB channel boost on my Denon. Here is my next question. On the back of the PSW111 Sub Woofer I have a switch for "Phase". It is a toggle switch from "0" or "180". What exactly is the phase toggle? What does this do? Since I am feeding my PSW111 directly from the Denon AVR 1706 through the TFE SW Output does this switch even become a factor in the sound?

Here is how I have my PSW111 set up:

Denon AVR 1706 REceiver

LFE SW Output to the PSW111

All my fronts are set to small

SW Channel DB set ar 5 DB (PSW111 is set at around 50%)

The phase switch is used if you have a room null that cancels bass. It is usually not used.

So would I have this toggle switch set to "0" instead of "180"? Give me an example when I would have the Phase toggle set to "180"?

Thanks
