I have a new SVS sb2000 that I got dialed in about 95% (2 channel music) to where I could not determine sub location. I was really happy. Problem was, wife was not happy about the location. So i placed the sub back in the corner behind the left speaker and ordered the Anti-mode at the suggestion of a fellow 'Goner. All I can say is wow. The sub, in the corner where it was boomy and too blossomed before, is perfect. I like a bit louder bass than most. With the Anti-mode, I can be a bit bass heavy without the "boominess". Bass is very tight
I'm adding a second sub in a month or so, so I can use the 8033ii for a stereo sub set up as well.
I highly suggest this product!!
