Last time I brought up what I consider to be good alternative to big whopping bass traps, a side issue raised all kind of havoc, but feeling brave I would suggest that you consider the Cathedral Sound Acoustic Panels. They only weigh about 5 lb's, hang on the walls near the ceiling corners like a picture, are good value, and not expensive to ship (or schlepp when you move to a new space).

They work directly on standing waves, and not only is this usually the most difficult area of room response to address, but it also affects every harmonic right up and through the midrange. They won't cure all ills, but should get you at least half way there, and leave you in a much better place to address any remaining acoustic issues.

Hmmm, I have never seen any mention of these before. I will have to check out that link and see what they are all about.

Do you think these could work synergistically with some bass panels and traps from GIK or would these be best on their own?

Thanks!

  GIK bass traps work, the Cathedral panels do not. Before anyone flames me, I actually TESTED four Cathedral panels with the company's blessing. They sent them to me to test because they didn't know how to do that themselves. Proof below, where you can see no difference before versus after. Then compare that to three randomly half-filled garbage cans that actually did improve the bass response a little.

    Hey Ethan,
    
    Thanks for providing some actual data. I guess I can cross those of my list.
    
    For the time being I am leaning toward two GIK tri-traps in the corners behind the speakers and then 2 244 Bass Traps placed right together centered behind my seating position on the rear wall. These would end up creating a 4'x4' square basically.
    
    Any input or opinions before I go ahead do it?
    
    Thanks you so much to all for educating me a bit!
