Conventional wisdom on subwoofer placement indicates that humans have a hard time locating bass frequencies, so you can put your sub just about anywhere you like. Not in my case! I swear that I can (easily) hear where the bass is coming from. Maybe it's all in my mind, but I really think I can tell. I have 2 possible explanations for this... 1. My subwoofer is way too cheap/small for my large, high-ceiling living room. I know this, and I need to upgrade one day. The sound from my sub is hollow and boomy, and I often hear a "blowing over the top of an empty coke bottle" sound coming from it. Perhaps it is THIS noise that my ears are locating, and not the actual bass frequencies recorded on the audio track? 2. Perhaps the dimensions of the room and placement of the sub are sub-optimal? The room has dimensions of roughly 2.35:1 (I'm not kidding!!). If you divided the room in half, the HT is in the left half of this big open room. The right half is mostly empty space. With the sub located at the far left front corner (under the left front speaker), I can hear the sound coming from there. I'd even go so far as to say that my left ear starts hurting before my right ear does if I listen to very loud stuff. I've solved the problem by putting the subwoofer pretty much front-and-center. There is precious little real-estate there, though, and when I upgrade to a larger sub, It's going to have to go back in the corner. So, is it more likely that my sub is just producing audio artifacts of high enough frequency that I'm able to hear where they come from (and a better sub will fix the problem) or is the layout of my WIDE room such that I'm going to notice the problem if I put the sub in the corner no matter how high-quality that sub is? The HT is also the living room, and placement of a large sub anywhere but in the far corner is a problem. The only other possible place would be under the RIGHT front speaker, which is just about in the front-center of the room (but to the far right of th e HT area). I ask because I don't want to invest time in a DIY or money on a better sub if I'm going to have the "all the bass is coming from the left" or "all the bass is coming from the right" problem.
