What is under $5k speaker with best bass slam?

I agree with most of these, especially the Gallo Ref 3.1 (with the bass amp), and especially the Klipsch K-horns. Those are, to me the be-all, end-all in Rock speakers. Additionally, for "slam" the Definitive Technology SC 7000 are pretty awe inspiring. One last vote, the best slam I that I have ever heard, was a buudy's Joseph Audio Monitors with a Talon sub. The sub definitely helped.

OK, I answered this previously, but thought that I would chime in again with a much different answer. I finally have my new sub (SVS PC 13 Ultra) tuned into my front speakers (Maggie 3.6R's) with a Velodyne SMS-1 sub equalizer and man, SLAM!!! Of course it's mostly the sub, but it really makes a huge differnce, and it's very well integrated. No sloppiness and a huge amount of air being moved. Songs such as the helicopter intro track and the beginning of "Another Brick in the Wall", the kick drum on "Hotel California", Toni Braxton's "Your Makin' Me High", and the first few bars of "Dead and Bloated" literally explode. More subtle and measured bass passages such as those on the whole Tierney Sutton album Dancing in the Dark, are fantastic as well. I'm happy about the Slammin' combination. Big loud sub tamed with the Velodyne system, and integrated into my Maggies. Very highly recommend. Well the Velodyne system for sure.
