Nasty slap echo

Oh jeez, now I gotta go and check my comfy Scan leather swivel/recliner I've been using for years to see if it is mucking up my sound....:-)

You say that in jest, but if the top of the chair is above your head it does affect what you hear.
A few years ago my wife bought me a very nice leather chair for my birthday. When I picked up a low-back chair at a garage sale for $5, I was afraid it would hurt my wife's feelings if I moved the expensive chair to the side. The $5 chair made a significant improvement in the sound so it stayed.

Has anybody ever made some DIY "room Tunes" using Owens Corning 703? I was thinking of picking some up and sticking it in the corners and maybe ceiling wall junction points.

"You say that in jest, but if the top of the chair is above your head it does affect what you hear. "

Yes, in jest, and yes it is above my head (when not reclining) and yes can no doubt affect what you hear, leather or otherwise FBOFW, due to proximity to ears.

A cheap easy tweak to experiment with....

Streetdaddy,
Yes all of my treatment is homemade. it's very easy to make. I used rockwool not 703 - much cheaper and works the same. Make a frame the size you need, place in 703, wrap with a breathable material and hang on the wall.
For higher freq. you can use 2 - 4 inch 703. To absorbe lower use thicker 703 -multi layers, Keep the back open, no backing to the frame and when hung have the trap way from the wall to increase the efficency of the traps.
You need them at the first reflection points, and as bass traps (thicher ones)in the corners.
That will be the starting point. From there you can add to it if needed. Also measure the freq response of you room usng REW. You will be suprised to what you actually are hearing
