Bass Traps

Seeing an acoustician and/or learning REW are wise choices.  Bass problems and treatment should be dealt with objectively.  The graphs in the review are evidence of effectiveness.

I remain an advocate for the AVAA traps but only if you have some assurance that they are the right choice and that there are not less expensive options. 

I have a friend who is running PSI Audio AVAA C20s in all four corners of this listening room.  This is a different unit than you asked about but I will say that this room running the active traps is the best sounding bass I've ever heard.  I think this is worth pursuing.  Good luck and cheers. 

Just one question why Rockwall and not Owens Corning 703 rigid panel? 

OC 703 is not very effective in a 6" thick application. It won't reach very low. 6" Rockwool will make a better bass trap.

I almost pulled the trigger on the PSI Audio product but felt it would not contribute much beyond what a distributed bass array system would. The graphs at the end of my Virtual System photos show the benefit of a DBA, which also provides other enhancements beyond decreasing bass modes, such as bass extension and better imaging. 

I am curious as to whether Kal thinks the AVAA could still provide additional benefit.

@kr4 can I place the PSI AUDIO AVAA C214 directly behind the couch of my sitting area or on your experience is it better to keep it upfront.  I can probably only do 1 unit now and a 2nd one later
