Best place to put a single subwoofer?

I know there are many opinions regarding subwoofer placement. I have had multiple subs (4) all in the same listening space. Way too much! I have had matched pairs hooked up in stereo. Right now I own only 1. It is part of my dedicated 2 channel music room and not a theater system. I have a pair of MBL 101e Mk2's which are excellent speakers IMHO, and they produce POWERFUL bass in their own right. However I am a bass freak (as noted above), so the harder it hits the better. Plus I tend to listen to a fair amount of rock music which I like to play loud, (hence MBL 101e's). Right now I have my sub positioned dead center between the two Radialstrahlers and it does ok. But I feel as though I'm missing something and that I ought to do something to increase performance, although I'm not exactally sure where to go with it. Not too many places I can move it to, but input and suggestions would be much appreciated. I have tried moving it closer, and then farther away from the wall but have not noticed any dramatic improvements. What about bass "suck out"? Could I be having some cancellation issues? What things would you Audiogoners do to improve on (already good) bass performance?

My best 2-channel placement was located after I placed large carpet sliders under my SVS Ultra 13 with an adequate length of cable to reach all possible locations. Sliders made it very easy to relocate and re-evaluate the responce.

All the routinely recommended locations were tested. I found one position 4 feet outward from my left main to sound best. Both mains (sealed) and the Ultra are nearly against the walls. A REL also sounded best in the same spot by far. This location was definately best for my room design.

When I tested it 4 feet from the opposite right main, it wasn't nearly as musical, tight and precise after readjusting the set-up.

A side note: I run my Ultra in the sealed mode for 2-channel to minimize port noise, performing somewhat like a rumble filter. The sealed mode helps minimize low frequency artifact from different sources, too.

Hello Fellow Audiogoners, been out of town for a few days, just rolled in at 10:00pm (P.S.T.) from a concert at the ORACLE Arena in Oakland, California. Mrdecibel, no new developments or news to report as of yet. Probably do some experiments n' stuff this weekend. Despite the fact that I think I have done alot/exhausted all the options...there is SO much good stuff here! Much of it worthy of my efforts and full attention. Several of you have offered me help and input far beyond what I would ever have imagined! Thank you all. I have had several direct emails from folks (who haven't even participated in this discussion), and Mrdecibel I WILL be emailing you- for sure. I definately want to gleen more input from you. So far good stuff. Very informative indeed. Stay posted folks. Something WILL happen. I will get to the bottom of this bass "situation" with all yer help. Then I'll have a big party and invite everybody over for beer, cigars , and music listening! You think I'm bullshitting right? I'm not. Love to share the joy with everybody!
