Update: Discussed my issue with Glenn from GIK... purchased 4, 2'x4' monster traps with diffusers...

Another thought that I had is to use a full range right behind the listening position and the limited ones on either side... maybe use 3 total then for symmetry...

I am thinking of getting 4 of the 2'x4' monster traps and place them behind the 6' couch... that will allow a 1' overlap on each side... I wonder if I should tip them a little away from the wall alternately... would that improve the absorption? I will probably make a "bench" for them to sit on...

I can't believe your timing! Thanks for posting. I was just going to order GIK Acoustics 242 panels to put behind my couch!!! I have been noticing that if I lean forward the improvement in the clarity of sound is dramatic.. I even pulled the couch forward so I was uncomfortably close to the...

I wish I could spare the space to move the couch... in front of it is the Velodyne Subwoofer.. then a chair for the computer desk... and lastly the computer desk... all are as close as they can be. I moved the sub but it seems to be better on REW being if front of the couch... and other places...

Added the separate channel measurements….

Whoops.... I came back to my PC and found that there was an error uploading the photo of the back wall... its an older picture. I have since removed the pictures hanging on the wall.

Here is the back wall.... all the surfaces are in separate pictures attached to the original post... Thanks for looking...

Yep... after earlier work to check each side was done I have done both together... Other posts told me that it averages some of the acoustical anomalies.

I am guessing that the hard polyurethane coated boards of the Helmholtz resonator behind my listening position is the culprit… It is 24" behind the measuring mic and the wall is 10-12" deep behind that surface... I re-did the measurements and propped up a 2'x4' piece of 2" thick auralex (which...

I love horn speakers... super efficient... and therefore less "Doppler". At extreme levels the cones hardly move let alone at regular listening levels. I though this thread died like a rock in the ocean! Deep and fast! I uploaded the latest mdat... the foam in the ceiling was replaced a few...

Well... the issue was REW was showing corrupt data! It turns out that the Focusrite Scarlett 2I2 driver was not playing nice in the sandbox. It also was causing some issues in JRiver's Media Center... Focusrite tech support suggested to unload their driver and let Windows use its WASAPI...

The Helmholtz wall is 9.5" from the face of the board to the back wall. As best as I can feel through one hole is around 6" of insulation. The boards are 7" wide and 3/4" thick. I started some new baseline measurements before I started moving stuff and measuring again but ran into one of the...

So I have tried moving the sub... multiple places not much better... I even put masking tape over the slots on the Helmholtz wall... didn't see much difference on the REW plot... maybe masking tape isn't enough... I looked at the Dirac Live web page. Is it a software driver, in the end, that...

I need help on my listening room that I made thirty five years ago… I made it but then due to the WAF it sat mostly as a museum. Now that I am retired I want to tune the acoustics of this space. With the advent of REW now it has showed modes and other ugly things that would have been theories...
