I'm sure I could probably find this in one of the 1000's of posts, but I don't really feel like looking thought them all right now. First of all they have two models, is the more expensive one worth it? (I know that's a rather broad question). Moving on, Are these one specifically made to be bolted to furniture? I thought I remeber one that you just sat the furniture on top of, I imagning things? Lastly I do have an extra receiver around that I can use, but I was wondering if this would work as a workaround...From the LFE out, use a Y adapter, send one to the Sub, and the other to the bass shakers. Since the lower model uses wires instead of an RCA jack, I'll have to find something to make the transformation, I'm sure radioshack has SOMETHING that can do that. Anyways, what I was thinking of is instead of a sepearte receiver just using an in line volume conrtol. There's gotta be something out there, even a dimmer for low voltage wiring would probably work. Does this seem plausable?
