IMO, this thing is not really an effective tool, as it's possing to be from my impression. It looks like it just gets the sub off the floor. What that does is puts the sub acoustically higher in the room, yes, lessening the floor floor to ceiling bass mode(s) somewhat(largely depending on ceiling hight mind you), and not much else!
If your thinking it's going to work like a bass trap, think again. This is nothing more than a pedestal for your sub from what I can gather.
realistically, to do effective bass absorbtion, as implied from the name, it would have to be much much larger/thicker to effectively absorb excess bass in a room! a little cube isn't going to do anything to ameliorate bass energy, sorry.
Often, yes, you can reduce the boundary reinforcment multiplication by moving a sub away from boundaries as well...in this case, by moving the sub off the floor. With an 8 foor ceiling, you'd be lessening the 71hz bass mode by a few decibles by getting the sub another foot and a half off the floor, yes. Not much else however. (most people aren't play9ing their subs over 80).
To me, this product is barely worth a try. I'd just try moving the sub off the floor first to compare before plunking down the cash on a cool looking pedestal....because that's all this thing really is. Heck, email www.rivesaudio.com and ask him what he thinks. He's also an acoustical guy.
