I'd definitely be interested in that, its the biggest complaint that I have at the moment, well that and lack of bass below 35hz.

Can you reveal anything about the construction of the Confidence (PM if you like). I've found that most of my bass problems are related to the position of my speakers relative to the rear wall. If I move them a foot into the room then things are improved in the problematic region I was talking about. I've tried piling up the corner traps I have now behind the speakers but this was less effective than fixing the traps into the corners of the room and between the wall/ceiling.

From my meagre experience I've found it very easy to fix my region above 200hz - I played with placements and settled on what you'd expect from conventional wisdom, all in all it was much less critical than the 80-200hz bass range which is a law unto itself.

Where do you think these Confidence traps of yours will work best? I mentioned the real wall-loudspeaker distance as improving matters, would the trap work well directly behind the speakers? Like I said, I've tried this with the existing traps and it measured and sounded worse than with the corner placements.

I agree with Thorsten that dipole bass is superior to monopole for exactly the reasons I'm talking about.
