Too many subwoofers?

[magister]

Thanks for the extensive reply. I do have Jim Smith’s book already. (For those who haven’t heard of it, I agree with you that it’s very useful.) Based partly on his comments about using an RTA, I have recently tried to measure my room; see this post. As I said in the other topic, my room is such that I don’t have much leeway with speaker positioning (although of course even small adjustments can make an audible difference). I recently acquired a pair of Magnapan LRS+ speakers, their bass performance has exceeded my expectations, but it’s still nothing like what I got with the speakers I’ve been using for a very long time; hence my interest in subwoofers.
