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

Tvad,
I am sorry I forgot to say that I'm going to setup a new system for bass slam. Although I am currently happy with my Ayre-Harbeth setup, I'm going to setup a dedicated bass slam system in 400 sq ft space.

if its a viseral thing that you're fishing for...that live music has...drum kicks, etc......ohms, shahinian, castle, gradients and other loudspeakers that are multi directional, do this incredibly

Listen to Gallo 3.1 with or without the amp that you can hook up or leave out. 2,495-3,295 range for the speakers.

Hi Dh4kim

Asking for the "best" of anything will generate multiple impressions. For slam, a driver/drivers with a large radiating surface is necessary. Slim towers with multiple 6 or 8-inch drivers won't do. At least 10-inch driver(s) are needed. The amount of slam is also room dependant. A pair of speakers with 12-inch woofers in a small to medium room can provide slam, but in a large living room their slam will be lost. The aforementioned JBL, Klipsch, Tannoys, ATC, and maybe the Von Schweikert speakers will all give you slam. I will add B&W 801s to the list. But you can't get away from large speakers if you really want slam.
