Nasty slap echo

From those pics that room looks extremely lively. I'd suggest studying up on room acoustic treatment at one of the many sites such as Ethanwiner.com or Gikacoustics.com. Plenty of good advice. Your room seriously needs it and your equipment deserves it.
Treatments made a huge difference in my room.

Funny you say that. I was just revisiting Ethan's site. I have 2 mini traps in each corner behind the curtains, and 2 minitraps leaned against the wall behind the rack. Another one on the right wall leaned on the wall just past the first reflection point.

I just took down the absorption panels on the side walls. Carpet is wool. I am thinking of making some DIY room tunes and sticking them above the crown molding in the wall ceiling junctions to see if that tames this pinging sound.

Did the pics come through for you?

Here they are again...

Pics came though for me.
Reminds me of when I was afforded a dedicated room after our last daughter left for college. The room was totally empty when I moved in, what an echo.
