Best speaker that Proac ever made

My personal favorite is the response 3. That also is limited to what I have heard. I use 3's at home, and have no intention of ever selling them. I'd love to have the funds to try the 4 or 5's.

I have the 3's, and love them. They do need the right amp, and room. I would guess 12 X 12 would be a bit small. I tried several amps and was so disappointed I wouldn't even use them. My friend has them running w some vintage threshold gear, so I knew what they could do. They need good power or you won't like them. I've got a big Arcam HT amp driving them now and I'm happy. It's still not the perfect match, but does the trick at the moment.
