I gave it another listen today and it's pretty boomy. I don't like it. Is it reasonable to assume that its current location, which is boxed in by 2 walls, a couch, and a side table, could cause the boominess. Tomorrow I'll have to try a new location.
Can't do a lot of home theatre testing these days with a demanding girlfriend! I swoop home real quick, listen for 10 minutes, then when I'm back at her place ask for advice online!
