OK, so one thread here inspired me to start delving into a topic that I've not really pushed into a whole lot before: room treatments. As it stands now, I don't have any dedicated treatments, though by some sheer dumb luck and a little intelligent design, the placement of the furniture in my room has yielded what I'd qualify as respectable results. So what do I have now? Well in the rear of the room, I've got a rather large shelving unit plus some other assorted furniture which ought to act as a half decent diffuser. The side walls are largely bare, but on the left side of the room, I've got a recliner placed right at a first reflection point, and on the right side, a piece of my sectional also pushes into some first reflection points as well. My thought here is that a couple of well placed heavy quilts could be useful in helping to absorb some of the mid to high frequencies. Outside of that, I'm contemplating a few acoustic panels for absorption to help cut down on the decay, although the prime spots where I'd think to put them are already covered with the aforementioned furniture, and I'd rather not spend large sums of money on nice looking treatments for little to no worthwhile effect. In terms of low end response, I think I'm fairly lucky with respect to my listening position. Response from 100Hz on down is reasonably flat, with a slightly rising low end. I can live with that and I've never really had big complaints with the decay time of the bass in my room at my listening position. Probably the biggest issue in my book is a bit higher around 150Hz where the front stage of speakers exhibit a moderate dip (somewhere on the order of 10dB, though I've found that Audyssey does help a little with this, probably by boosting the heck out of it). My main concern with bass trapping to attempt to fix this is that I'd risk screwing up everything else. Also well...bass traps are ugly and I don't have a lot of corner space to put them. Any thoughts?
