Messing around in the avr settings, trusty tape measure and calculator nearby I realised a couple key things.

A stereo integrated amp with speakers/sub is just outclassed by a properly dialed in AVR/Processor with a sub. I own both types of setup. Being able to dial in speaker distances and subwoofer crossovers and hear the effect of the signal sliding out of phase then return as the other channel is matched is ridiculous. cool

I didnt even come close to getting the subs right in the listening room with the manual dials. Night and day.

The HT room is literally empty with a folding chair and I can already hear its potential. cool I love this stuff.

Get on it Matt!!
