does anyone use subwoofers in their setup?

[thumb5]

So I set the delay for the subwoofer preout as mentioned above and from an sw integration perspective, it sounds like a step in the right direction. I have now been experimenting with the phase settings (my sw has four, 0,90,180,270) and percieve 90 to be the one which gives me the best results, but what exactly is phase doing? I read the sounddoctor article, but still don't get it ...

Can someone enlighten me?

Yes, confusing...from what I've read, it's typically a delay adjustment expressed in terms of phase at 80 Hz (by convention).  You might want to check that in the user manual for your sub-woofer, if you can.  If that is the case for your sub, by my maths that means each 90 degrees of phase adjustment corresponds to a delay of about 3.1 milliseconds (360 degrees = 1/80 seconds = 12.5 milliseconds).
