There are plenty of subwoofers available that can fill a large room that cna go in your corner or otherwise. SVS is one I would recomend. also Hsu subwoofers are a good company from what I have read. You can build your own custom sub in your home it just takes the nohow in the driver selection,amp,and enclosure that you want to use. I once installed a trio of EV 18" subs with a QSC amplifier running 2 ohm with fan cooling in a guys basement and it was thunderous but he would turn them off for music which I don't blame him they were not meant for that anyway. My point is that the amount of bass you produce is not the quest it is how well and how detailed you can do it without disrupting the sonic flow from your main speakers and that they meat at grounds that you you cannot tell one from the other. That is the ultimate test of a sub, most cannot do it in that they put out something that gives them away like a sonic signature or a difference to the mains. Buts thats for music home theater is a different battle all together.
