DSPeaker Anti-mode 8033 ii works wonders with my new sub

Good to hear you like the Antimode. When I acquired mine I called the manufacturer in Finland and talked with one of the engineers: with the Antimode the best position for the sub is well into a corner. This gives maximum corner reinforcement for more power, smallest dips, but also biggest peaks. The first two effects are an advantage and the peaks can be dealt with by the Antimode. It works well, and in many situations the sub will also be less visible.
I am similarly saving for a second sub. That will not be stereo, but dual mono. The Antimode 8033 does not have stereo outputs, and that would not be quite so desirable either. At these frequencies bass is completely non directional, and dual mono subs give a smoother response than stereo subs.

Thanks for this post, I'm going to put my sub in the corner and try it. I pulled it toward the listening position to account for any delay in the 8033.

I use one with a pair of 15" Rythmik sealed subs to augment the bass on my Avantgarde Duos. It is effective and pretty straightforward to set up. Some of the test tones while in set up mode are earth shaking. Does the job at very low (relative) cost. I'm rolling off very low (55hz) and steep (-24 db/octave) and feeding the subs from a second set of outputs on the line stage, so nothing is in between my main amps and speakers. 

My sub volume is now just above the 9 o'clock position and it blends great at all levels. Just the right amount of whack and fullness that sound perfect and balanced. When I do late night, very low volume listening, I have an EQ in my preamps processor loop to use basically as a loudness function. 

I say the Anti-mode 8033 (I have the version ii with the extra calibration steps) is well worth it. 

For stereo subs, the Anti-Mode 2.0 Dual Core is necessary. There are a number of them available used right now for around $500.
