Doubting Sound Treatment ?

3 years ago I purchased an 11 piece Kit from a reputable company. I noticed improvements, but wasn’t instantly blown away. Now 3 years later I took it all down for a home move. Bass definition noticeably less. Instrument placement less good. Overall coherence less. Not a as intimate. Far less enjoyable, simply put. If your on the fence, get past it. Better improvements with the treatment than most of us hope for when we change Preamp, Amp, or Speakers. Doubt no more !
Cheers !

For the DIY set, work diffraction just as hard! As most dedicated audiophile rooms I encounter lack natural and engineered diffraction. You can build replica RPG diffuser fairly easily.

Rack along a side wall vs centered between speakers or worse in a corner is in the valuable Jim Smith book

Rack along a side wall vs centered between speakers

Correct, worst thing you can do for imaging and depth perception, is have your equipment between the speakers. Speakers at least a min of .5 to 1mt in from the side wall, and as far out from the from the back wall as you can, if? you don’t need the extra bass loading the back wall can give.

Cheers George

Does anyone have firsthand experience with Acoustic Fields or knowledge of their Active Carbon absorption technology?

I treated my 16 1/2’ by 18 1/2’ by 11’ high listening room with Roxal Comfort Board. Just placing the wrapped packages of raw materials in the room immediately improved the sound.
Now my bass traps are in all corners; looking good and sound is amazing. 
No doubt!
