Three subs - placement options?

[nomorefours]

Hi, All

My room is about 14' x 23' x 8', fully soundproofed and acoustically treated.

I already have one SVS PC-Ultra, and I am looking to add two more subs to even out the room response. My receiver can manage three subs independantly with full EQ functions (Denon 5308), so I don't think I am too worried about getting 'too much power' since I should be able to calibrate everything reasonably well.

I am still trying to decide between adding inwall subs into my columns on the left and right walls (the SVS is on the stage behind my screen), or else two more subs also placed on the stage, in which case they would not be in-wall models, but would have to be compact, as I only have about 16" or 17" between the front wall and the screen wall.

Any thoughts about which option would give me smoother overall room response - L & R in walls, plus one sub on the stage, vs 3 subs on the stage?

Any input is welcome...

Thanks,

Doug

3 subs on stage would be better.

3 subs that are similar to each other in performance would be best.

also, instead of the audyssey, try to research the Velodyne SMS-1

Here's an article that may help you decide: http://www.harman.com/wp/pdf/multsubs.pdf

I'd likely do 2 in front and one in the rear of the room. I'd avoid subs in the columns purely from the standpoint that they're not movable. If that ends up being a 'bad' place which causes response issues, there's not much you can do about it via movement.

I would do 2 in front by the front speakers and one in rear center

When doing multiple subs they should be in groups of two.

i.e. do one sub, two subs, or four subs all of the exact same make & model. That will allow the best overall response within the room. A third sub can potentially detract from the balance achieved with a pair. Placement becomes more difficult with three as opposed to two or four.

I agree here Chris. I once had (3) subs and onlt two of which were the same brand/size. More specifically, I had (2) 8" subs and (1) 12" sub. This proved to be more or less a nightmare. I am sure there are some here that could have integrated them much better than I. However, I ended up selling my (2) 8" subs. This is very good advice Chris.

Is there a budget for this project?
