Stick with Yamaha's YPAO or pick up used SVS AS-EQ1
I'm using a Yamaha RX-A2030 receiver with Yamaha's YPAO system. I'm considering purchasing an SPS-EQ1. From what I've read it seems to do much better EQ on the low end. I will probably be getting new subs soon. Leaning towards dual SVS SB-2000 subs. The system is in the living room which is part of a larger space, about 5000 cubic feet would be my guess. I listen to about 95% music, 5% HT. We're having a credenza built that will house the subwoofers. I figure sealed subs would be a better choice than ported ones if they have to live in the credenza. I'd appreciate any advice to help me with this decision, except the advice to take the subs out of the credenza. Unfortunately that's not happening.
Also I learned a little about Audyssey. I know that there's MultEQ, MultEQ XT and MultEQ XT32. I just want to verify the version that the AS-EQ1 uses.
