I've searched for and read the previous subwoofer threads, but my problem is somewhat unique. I'm getting 5 identical speakers that lack bass, rolling off at 166 Hz (-3 dB). I'll probably add woofers to them eventually. For now, I'd like to crossover to my subwoofer at 200 Hz, or maybe a little lower. I will shortly get a new sub, probably a forward-firing VMPS New Original Sub. My theater's room is irregularly shaped both horizontally and vertically, roughly 20 feet high by 30 feet deep, with a cathedral ceiling that starts at 9 feet high. The RPTV is at the lower end. There is no one back wall, as it is broken into 4 pieces at different distances and elevations. The listening position is in front of a stubby wall that is 10 feet from the RPTV. Assuming I'm going to have at least moderate problems with bass becoming directional with this high crossover, where should I put my subwoofer? A) As close to front-center as possible. B) Get two subs and place them under or next to the mains. C) Behind the couch, against the stubby partial wall. D) In a front corner. E) Place the sub where you sit, crawl around until you can't hear where it is, then put the sub there.
