I'm wondering if I want to use one of these type devices... I've got a single 210, and thus it is sitting low on the floor. I like it tilted back a bit best, so that the mids and highs are pointing at my ears instead of my feet. I've tried it horizontal, vertical, tilted, whatever. Now I'm wondering about either getting it off the floor completely on a stand, or using an isolation riser which would eliminate coupling (but not tilt the cab), or using a wedge, which would tilt it back, but maybe not isolate/reduce coupling as much since the rear of the cab would still be touching the floor. Of course, I might find that my low end totally disappears if I decouple the amp - I don't know. I like the idea, at least in theory, of hearing the sound out of the speakers and not the sound being transmitted through the floor as a big speaker cone. But maybe I need that "cone"... And before you say it, no, I'm not looking to buy a stack of cabs just to elevate the 210. It's seems plenty sufficient in the loudness and amount of gear to lug around categories! Anyone with any experience using any of these methods - please comment pros & cons!
