GIK suggested 3 bass traps panels 24x48 but at the back wall since my couch is leaning on that wall.

Sounds like good advice. Having your couch agains the wall isn't ideal (but, most things in the real world aren't ideal!)

Here are the three 244 GIK bass traps.

Whoops... missed the pictures showing that you bought!

Looking at the pics, I'd be inclined to move them down to be directly behind your head...see if that changes perceived sound for the better

Yes, the only problem with that is the panels stick out 5.25 inches. People would rub the head against it.
Right now the way they are we can hear the diff. Especially my wife can. The bass was heavier in some areas more then others but especially at the MLP you could feel the ear pressure more before. Now is more spread out and even I think.

Re: What happened to the bass?

Does Bryan recommend them being that high? I would think your head should be somewhere around the middle of the trap. Right now you are getting all the reflection from underneath them...untreated.

Idk I emailed Nick a pic. It's just hard to place lower as I mentioned earlier because it sticks out 5.25 inches and people would rub their head on it.
I can move the couch forward some but with tile it will slide back eventually.

Re: What happened to the bass?

Well if you can measure with REW both ways, you will know for sure. That's what I would do for peace of mind. And keeping an eye on the couch...I bet everybody would learn to keep it pulled out.

Is the trap suppose to go behind the couch back or just a few inches above it?

Re: What happened to the bass?

Bryan will hopefully correct me if I'm wrong. I think the whole idea behind room treatments is to correct the sound at the PLP. That being said, I would think that all our treatments should be placed accordingly. That's why I said "centered/ear level." Other factors can of course affect results...thus the need to measure to be sure. And that's the fun in setting up a room...seeing our acoustic results blossom.

Re: What happened to the bass?

Ok, GIK told me to bring them down to ear level. I know what ear level is but does that still apply if the ear level in my case is the couch back?
In other words my ear is not above the couch back.

Re: What happened to the bass?

Again, Bryan will know for sure. I think ear level, center of trap. A thought did occur to me however (I hope everyone will chime in on this). I'm thinking the rear wall is the most important place for diffusion. Only in that it is the primary source of the bounce back reflections. Am I correct in thinking we should do the mirror test on the back wall? You would have to turn around in the chair @ the MLP and slide the mirror form side to side until you could see the main speakers. Place diffusion panels at those points & absorption panels around them + the corners. Is this what everybody does? This should scatter most everything @ the MLP.
