My next step in sub-room integration is to learn more about how Trever is doing it. Best I’ve done is set my 4 sub levels to match the main speakers. I need to learn more about phase, measurements and how they relate to practical adjustments … I.e. just get more applied experience … theory only goes so far.

This fellow explains how I do it in an easy to follow format. I default to 80hz for center frequency and once one sub is set, I phase align the other subs to it with their phase dials if not equidistant to the mlp. Measurements are at the MLP for measurement reference position for all traces. Since my setups are usually symmetrical I use the left channel with nearest sub and go from there. The left channel and right channel are phase aligned by default in a symmetrical setup. If both subs are on the front wal, say at 1/4 points, the same delay (distance) setting can be used in the AVR. If different, you can do sub at a time. In the end they should sum.

This guy is excellent and is much more experienced than me hands down. He has great content in general.
