This in an interest check- I'm going to be trying some RealTraps acoustic treatments, and so I'm contemplating taking the leap of faith and selling my 8th Nerve stuff off.
I've found it to be maximally effective with minimal size, but curiosity has gotten the better of me and I'm going to go with something new. Since I can't use them both, I am considering selling the 8N.
I have 4 Adapt Triangles in very good condition and 9 Response Seams & 2 Response Corners, also in good shape. All are Black. I think Nathan may have tweaked the Adapts recently, perhaps after I bought mine. This is enough to treat all the ceiling/wall corner junctions, the midpoints of all ceiling/wall and wall/wall corner junctions, plus a two of the floor/wall corners. You can read the comments of many satified customers at AudioCircle & elsewhere.
I have the original packaging & mounting stuff for the Adapts; the Responses I'd pack in a box (they're flexible like long pillows and can be folded up). I'd probably be asking for $650 + shipping for all 15 pieces. While I'd prefer to sell it all together I'll entertain offers for parts. I could use the cash to apply towards my RealTraps purchase but would consider trades for something I could use in my new HT (eg a good sub, video scaler, upsampling DVD player, etc).
