Question: Sound Treatment behind the Listener?

Timely thread as I'm looking into this as well - absorbsion and/or deflection on the rear wall. @vinylshadow  , which GIK panels did you put up? Thanks.

Perfect, thanks. I'm thinking about moving my 242s to the rear wall but they don't have scatter plates - maybe I can buy those sep and then pull the staples out of the fabric and put those in and restaple. I'd probably make a big mess of things though.

That youtube vid posted earlier is excellent. I'm thinking about ordering  2D / GIK polys to put next to (new and larger) GIK 242 panels on my side walls. 

I just need to take a smidge of treble energy out of the room - not much but some - well quite a bit for some recordings but none to very little on others. Resisting buying an EQ.

Thanks Vinyl Shadow for the info.

I'm getting some advice from GIK but also just started a dialogue with Jeff at HD Acoustics who I found when searching here. It won't be free but it will (should?) be unbiased and sounds like he knows what he is talking about....because I don't w/ acoustic treatment on the rear wall.

@charliech , do you think having Townshend Podiums would reduce the need for so much bass absorbsion? I still need to measure my room but when walk around the room I don't sense that much bass pretty much anywhere. That said, I still feel it in my listening chair when rocking out.....which is a good thing for ....for me anyway.

Thanks. Good info. I think you are mixing up me and the OP though, just fyi. My rear wall has 4 ASC sound planks on it directly behind my seat (6" apart) and is open on one side to the rest of the house and the other is curretnly (!) drywall. I'm discussing w/ GIK about that now and a few other things. He is suggesting thick bass absorbsion with deflection on the rear wall also. One issue is that I can't go more than 4" since that is also essentialy the wall to the hallway to our bedroom and can't stick out too much.

The good part is my room is very close I think to where I want it - just need to tame some highs.

Ozzy, you may want to measure your room. If you don't have any WAF considerations and can treat as you please I would measure. 

My GIK rep had a great point which is that, although he rec that I measure my room to see what I'm working with - because it is the LR and I'm WAF limited, that it is less important. This is because even if the measurements call for certain treatments, if they don't look like they will look good in our LR, I'm not buying it.

That said, I'm not tech savy at all and every time I start watching a youtube vid on REW my brain turns to mush. Also, I don't have streaming so I don't have a good way to hook up my laptop to my integrated amp (Primaluna). Someday I'll make the effort when I have more time, but I don't now - but again, it won't make much difference anyway since I'm for the most part limited to panels with Guliford fabric (and not ones with diffusion over top).
