Keep in mind a couple of things about bass traps. Most of your cosmetic appealing bass traps don't do much below 80-100hz. I remember one of Ethan's test where he had several (and I mean several) bass traps standing around his room. There was very little, if any (I can't remember exactly), effect below 80hz. And those weren't very cosmetic appealing either. That doesn't mean that the area above 80hz is not important though... but we are mainly focusing on subs here. Monetary cost might play a factor in this too... for several folks who are looking for the cheapest method.
I have heard of bass traps that tamed frequencies below 80hz, but they took up nearly an entire back wall and it was lots of trial and error and very costly to strategically target a particular response peak.
So for sub 80hz and below... I might would stick the parametric eq back to #2. lol |
True, a sub's output is almost always 80Hz and below, but "bass" extends a few octaves above that. And the PEQ is usually only on the .1, which leaves acoustical treatments as the best way to deal with the 100Hz - 300Hz range.
Right-o as well on the "cosmetically appealing" issue; unless one is starting from scratch with a large empty space allowing integration of a huge trap (or traps) into the theater design, tacking things onto walls and corners is the only thing to do. StudioTips SuperChunks - the 34" face design, is effective into subwoofer range, but are awfully huge. And covering them with GOM doesn't make 'em any smaller either!
I bought some OC703 and am working on building the 24" face version. By doing both wall corners and the wall/ceiling corner behind my false wall, I'm hoping to minimize the traps needed in the room itself. The 24-inchers don't get as low as the 34's, but most of my problems are 100Hz - 300Hz, and if I can get some low bass absorption, EQ'ing will be that much easier. Sooo, your conclusion is pretty much right on for subwoofer frequencies.
