Subwoofer placement


There are so many different ideas and opinions on this. Corner, center between the mains, side walls.

What have some of you found works best? Sit the sub where you sit and crawl around the room looking for the spot where it sounds best? Or just stuff it in a corner?

Finally, do subs with automatic room equalization functions render placement a relative non-issue?

Revamping my room, looking for some thoughts. Thanks!

BTW,

I'm surprised by the ACI comment re: "near wall placement" as so kindly posted by Jax2. It's true that this placement increases output, but -IME- it also provides much smoother bass response. In fact, it's not even close, as measured by either StudioWizzard or the RTA function internal to my Velodyne SMS.

Cant beat center placement. I dont care what anyone says. I know better. HUGE difference!
I tried most of whats been offered and if you have a room that you can place the sub "anywhere".... I would try putting it in the listening position firing into the room and then place it where the bass is best sounding in the room.
I agree with with Tom as that is where YOU sit.
If you move from that spot(even a foot)you will hear a big change in the bass.
Two subs even out the layer of bass,so if you move,it sounds more consistent.I'd never go back to one sub.
try putting her where you sit as Tom suggests(as that's your
sweet spot),happy subbing.
with single sub have it in your listening chair then crawl around on hands and knees to find best spot while playing rolling bass line.

corners or walls work well.

Also, if you crossover at fairly high level (60Hz or higher) then try to keep sub within 3 feet of mains to reduce group delay. Or else, use digital correction to delay mains and keep group time with sub.

Once you have placement, play accoustically recorded cello to integrate with volume and phase. Don't integrate using same bass line you used to place, you need to get upper bass working with bass.
