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


Well I've watched a few of their videos and mostly they seem to be no nonsense. what do you think?

@shalommorgan I have a room with very similar dimensions. What areas did you discover had the highest bass velocity or were the biggest problem areas?

For me, the corners behind my speakers were the biggest problem so I filled them both to the ceiling. 

My biggest problem area is the mid bass above 100hz has a wide dip. It's the ceiling interaction...possibly combining with the floor reflection. If I take a big trap and hoist it over my head (and speakers) during a measurement, it mostly goes away. 

One day I may do a cloud with an attached scatter plate to deal with the floor and ceiling reflection dips. 

I keep a door open behind my listening position and that does a surprisingly good job of reducing bass build up.. 

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.
