I’m with Michael on the REW thing. While it might be a good route to go I’m not sure I want to take the time and effort learn it (so says the guy testing and opining on the AS-EQ1).
Like Casey I think I might prefer the ability to tweak specific frequencies since I agree that what I prefer to hear is more important to me than a flat FR graph or someone else “ideal” curve (Audyssey).
I don't really understand the receivers that do 3 subwoofer outs. A jump from 2 to 4 seems more logical, no?
Not if your just trying to keep ahead of the Joneses. They might be thinking that with 2 output you could Y-connect 2 pair to get 4. Also I might be the exception but 3 outputs would be perfect for me as at most I would have 2 subwoofers but would still like a separate output for the Buttkicker.
