Currently, my mains are DCM TF-600's with a 6.5 driver. These are a transmission line cabinet, and you would not think that the drivers were that small by the sound of them. I've heard some folks say they thought the DCM's were a little bass shy, but I think they sound fantastic. The bass is there, it's just not in your face. I listen to mostly rock music, and I have a bunch of Cerwin Vega's in the house, so that ought to tell you that I like it loud, and with a good bass kick! The DCM's will never have that slam, but that's a good thing! When I need to shake the walls, I just crank up one of the other systems in the house that have the Cerwins on them! The DCM's do everything else very well, with much better imaging and a better soundstage than the Cerwins. These are in my will, delihaus gets 'em when I go!
