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 !

Anyone here with firsthand experience with Acoustic Fields active carbon products that can speak to the improvements they experienced after installing them? 
@jdesj - I too looked into Roxul, Rock Wool, 703/704 and other products for a DIY solution. During my research I discovered many health concerns about those products. Not that we all don’t make calculated decisions daily, but with 2 young children at home, my conscience would not let me take that chance. 
Remember if you can ..the thicker the better ...don’t skimp on thickness and stay away from thin panels such as 1 to 2” they are basically worthless. 
Sound travels in waves that are longer for lower frequencies. Because of this short wavelength high frequencies can be absorbed by thin panels, while longer wavelength bass frequencies require much larger panels and shapes. So whether a 1" or 2" thick panel is worthless or not depends on the frequency you're trying to treat.  

But you knew all that. Right?
