I am trying to decide whether two subs are better than one sub. I have about 5000 cu ft area listen mostly movies and tv, medium loud, but when I turn up the volume want that earth shaking bass. I was looking at the two PSA XV15se vs one PSA S3000i anyone out there have any thoughts?

I have dual FV15HP's in an open living room over 5,000 cu ft and they hit hard and dig deep. However, they do cost quite a bit more than the PSA XV15se, so if money is tight grab the VTF MK2's. I've heard nothing but great things about it. You could also check out the PSA V1500.

So your saying the PSA XV15SE is not strong enough ...
I honestly don't know if dual XV15se's would give you "earth shaking bass" in a 5,000 cu.ft. room. They very well might.


... that I would need to go with HSU or Rythmik.
Nope, I'm just saying that I would. :)

I have a 5300 cu ft. space and to be honest. You will nee 4 of any of the mentioned subs for the truly shaking couch, chest and throat vibration and occassional blurring vision, lol. Great wooferage comes at a cost!

I have 3 XV15se in a 2400^3 room with one smallish sized opening to the rest of the house. They are reference capable down to 16-18hz. I think duals placed near field would do ok in your room but would not be reference capable below 25-30hz in your room. The nice thing is you can try them free for 30days. If they are not enough then simply return them.


For example: using data from the ULF thread based on a 5000^3 room.


Dual XV15se would net max output levels around 113.5db @ 20hz and 103db @ 16hz.


Dual VTF15.2 1 port would net max output levels around 112db @ 20hz, 108db @ 16hz, and 101db @ 12hz.


Dual FV15HP 1 port would net max output levels of 114db @ 20hz, 110db @ 16hz, 104.5db @ 12hz.


The point is, none of these options will get you reference level output below 20hz. The Rythmik and HSU will have a big advantage in the 12-16hz range, but again not reference capable. SO if you are chasing big output in the ULF region it might be time to look at Captivator 2400's or build your own ported 18's. I think the goal should be to have a reference capable system in the 16-80hz region if you are going to invest the money.



Dual Cap 2400's 15hz tune would net max output levels of 118db @ 20 & 16hz, and 108db @ 12hz. Now were talking! Big rooms need big subs. :)

+1 You could buy one for now and a 2nd later. 2 subs are better for room smoothing. If you was to hook up a room measurement mic/software (REW), you would more than likely see at least one spot where you are missing some bass.

Seaton is suppose to come out with the XL (Dual opposed 18 inch subs) soon.
