Side Loaded Subs

[Timbo]

Is having the side walls 8' away from the mains (room 25' wide, 3600 cube total) a benefit or a detriment for side-loaded subwoofers?

That depends whether you seek accurate response or boomy response.

In more general situations, if the designer has incorporated room gain in his design, the bass could loose some perceived extension. When full bafflestep is accounted for in the design, placement away from the room boundaries is a good thing. So increasing the distance between the radiator and boundary (regardless if the driver is located on the front, side or rear of the enclosure) will improve the situation.

accurate response or boomy response.

Side walls eight feet away will do this??

Naturaly we want it all, accuracy, extension, high spl. :W

Now back to reality, Build 2 10 x 18 x 48 towers, I should have an easy 3+ cube ft left in them after accomodating existing MT or MTM design, insert the biggest, baddest salad bowl in the side that this volume will accomadate and drive it with my 450 w amp and "correct" them with a BFD...

The side placement allows a "slimmer" appearance and somwhat higher SAF. I will treat it as a true sub < 80Hz, can I get into the low 20's or high teens with 2 15" and my lack of side wall re-inforcement?, the center of the cones will probably be out 18" from the front wall. And belive it or not, I do not have any spare corners the leave seperate subs in..

I don't think you'll have problems with that placement, but who knows. One of my corners seemed to work better for me than under the speakers. That is the beauty of subs, is you can place them where they sound best. I think you won't know if you have a room mode problem until you try it. But, you shouldn't have a problem with corner boominess.

With sealed subs, you will likely need to use a LT circuit to achieve lots of SPL in the low 20s and teens. Look to the Behringer DEQ2496 for this.
