Incredible thread and videos! I've learned more in the past 2 days of your videos than the past few years.
Hope I'm not too late to the game to solicit a little advise on how to go about the sub alignment in my system. I have a new AVR on the way along with MiniDSP. Already have a UMIK and familiar with REW.
My "theater" room is really a living room. Its 20X13 and open to adjacent rooms on 2 sides, to the tune of 10X10 and 8X10 openings, so in total it's large odd-shaped volume, and Ill be expecting my response to be all over the place. My question has more to do with the approach since my sub configuration is a little unique.
There are a total of 3 "unique" subs, but 2 of them exist as powered tower front speakers, and as such, their location is fixed. The third sub is mobile (to an extent; wifely and living-room type restrictions apply). The subs that exist in the powered towers will be further from the main listening area than the 3rd sub. Since those two are further, I'm thinking those should be the first to be aligned, followed by the 3rd. But here's where a little extra guidance is needed. Normally you would position ALL of subs for best response before all alignment activities (right?). In my case, where the position of 2 subs is pre-determined and fixed, does it make more sense to align those two as best as possible where they're at, and THEN position the 3rd sub to compensate for any nulls? And then follow with alignment of the 3rd sub to the powered-tower pair?
Thanks in advance!!
