Need help to seal the deal

[Killergurt]

Hi everyone,

I took care of everything in my system except for a subwoofer. I need help to make a decision and purchase, planning on buying on Monday.

My story:
Big room (900 SF + vaulted ceiling), not treated, open space living room.
My system- C2600, MC601's, PS Audio DS DAC, MX-122 (Surround), B&W802D1, HTM2D1, Klipsch Surrounds.

Usage: 70/30 (Music/Movies).

I am having a hard time deciding between one F113v2 or two SVS SB16 Ultra/SB4000, price is similar (I am thinking of sealed due to size limitations).

I have read many threads on theses forums and understand that the Fathom is a step above the SVS but I have never heard those Subs and probably won't be able to audition them at home.

I do have size limitations, the SB16's are probably too big and will hit resistance from my wife, the F113 and the SB4000 have better chance to pass. Unless you tell me to absolutely go for the SB16 instead of the SB4000- I will have to figure something out.

Any help is appreciated, especially from people who had a chance to use both subs in their systems.

Thank you very much for your help.
