Nasty slap echo

I'm not clear if the slap echo was there before you had the crown molding lowered or not.

A long time ago I remember walking downtown and entered a dome supported by columns (no walls). There was a slap echo as well that got worse the closer you got to the center. It could be the crown lowered molding can be at play here.

All the best,

I just looked at the picture of your room and I see why you have echo. The dropped crown molding is the least of your worries. ASC makes some absorbing panels that would work for the side walls. I would also try throwing some blankets over the leather chairs. Leather is a reflective surface that will cause additional problems.

Thanks for the help guys. I will try these one at a time when i get a chance and see what helps.
I guess i should have labeled this thread nasty slap "ping". I know when i clap in other rooms i hear an slap echo. This is a different sound altogether. Really weird.
I have a set of first reflection point absorbers from realtraps, but they do nothing for this sound. I removed them a few days ago thinking maybe i had my room overdamped.

May try to get some insulation and make some DIY rolls to set on top of the crown molding. Does it matter what R value? What have you guys used to roll them up in? Some kind of black fabric would work best visually. I could have my wife sew some tubes and stuff them, i guess.

How does the room sound? ...Sometimes a little echo can yield very nice ambiance to the music.
I know of at least one such room that has the most amazing bass and ambiance that I would give an arm for.

I don't know if trying one channel at a time would make it easier to find or not. But anyway, see if you could have someone walk around holding up a large bath towel (stretched out of course), to try and block that reflection. I'm thinking one channel at a time may be easier, but not 100% sure. Leather is bad for reflecting. If I wear a leather coat, I can hear all kinds of reflections off of it, in comparison to something soft and more absorbent.
