so bass traps in corners do nothing, it seems we have been fooled. or are being fooled.

For the people out there that buy bass traps and don't find much results...I have discovered:

1. The treatments are usually in the wrong places (low velocity areas).  

2. The treatments aren't thick enough or heavy enough...foam wedges on amazon are too lightweight even if they are really thick. My panels are wood framed and are around 20 pounds each. 

3. Try air gaps...a 3 inch thick panel with a 3 inch air gap is almost as effective as a 6 inch thick panel of same construction. 

4. The GIK 244 panels with the range limiter plate (flex range tech) are the best i have found for the size. 

Several posts on other sites about Foley taking money and not delivering the product. Suits filed evidently.

I have ordered his ACDA product in the past and it got delivered just fine! In fact, GIK took longer on a couple of deliveries.

@seanheis1 The front wall, front wall sides and ceiling above front wall required a lot of low frequency management.  To control 125hrz to 250hrz issue, ceiling required proper treatment.

Thanks for sharing. That's the best treated/looking small room I can remember seeing.

The only over the top thing that could be done is building in a floor cavity to deal with the floor bounce. I saw that once in a home theatre. 

Great work! I'm jealous.

That's a beautiful room.
