Subwoofer position
I have a large listening room. It is 22' X 30' with a cathedral
ceiling. I have a subwoofer in each corner. My listening spot is in the exact center of the room. I get very little deep bass at that position but when near the corners I hear lots. I know that corners are the most efficient place for woofers but is there a better spot in my situation? ---MIKE--- |

Subwoofer position
I may have just posted this in response to another posting on this
group. But, here it is again. The answer to your question is. Yes, absolutely. Without a lot of measuring equipment and a mathematical nightmare to compute a solution: 1. Place the subwoofer at your listening position (wherever you *want* the bass) and play your reference music through it. 2. Walk around the room along the wall and listen for the bass peaks. 3. Place the subwoofer at one of the peak positions along the wall and you 'll have that bass at your listening position. I have a 17' x 28' listening room with a 10' ceiling. Using this placement method, one 10" powered subwoofer has enough energy to sound as good or better than any of the IMAX or other theaters I've been to. Good listening to you.

Corner placement will tend to give you the most reinforcement, but
also has the greatest potential for giving you "one note" bass. Positioning and blending of subwoofers is always alot of work. Listen, listen listen is my only advice. I ended up with the subwoofer just off centerline, about 5 feet into the room and turned sideways (the cone faces the right wall). I have no idea why that sounds best to me, but there it sits!

Subwoofer position
That's good advise as was Stu-R's. The best position is one of the
least possible for most people due to lack of space there. Ideally, the sub should be directly under or behind the video monitor and center channels speaker. Since you have two subs, trying to get them closer together along the front wall and between the main speakers will work best. That gives you correct localization and phasing with little effort. Subs placed in corners will have more output, but that can be cancelled by the other sub, speakers, and room construction. So, if you get suitable bass levels from the front wall (switch both subs in the same phase), then that will also give you the most seamless transition with the main speakers and not cause a weird sensation from having the bass coming from afar. {A real simple fix that may avoid moving anything is to just try and switch one of the subs phase so that they are out of phase with each other. That would be especially effective if the subs were in the opposite corners.} Still, I always find it best to have them on the front wall where possible. -Bill www.uptownaudio.com Roanoke VA (540) 343-1250 "Philip Procter" wrote in message ...

Try moving forward or back in half-foot increments. Btw for a normal rectangular room (yours may not qualify, having a cathedral ceiling), some research done for Harman a few years ago on sub placement suggests the midpoint along each wall, for two or four subs, is optimal http://www.harman.com/wp/pdf/multsubs.pdf For a single sub I'd still expect corner placement to be best, as it excites room modes most evenly. -- -S.

Sorry - the subs are in the two front corners. Changing my listening
position is not practical. I tried putting one sub against the side wall in line with my listening seat. That helped a lot. The front wall is taken up with the equipment rack and CD storage. ---MIKE--- |
