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

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. 

@shalommorgan 

That's a beautiful room.

Thank you seanheis1 & ozzy62.

Everything you see in the room was designed, hand built and installed by me. Crazy amount of work! Well worth it! Total weight of all the material close to 3000lbs. Mass/ weight, proper design and placement all play a role in low frequency management. This allowed me to avoid using corner bass traps - not needed. For other rooms, bass traps might be beneficial, but not mine.
