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.
