New house and room size concerns

[kinggimp]

Soon I will be moving to a new house with a listening room that is quite a bit larger than my current one. Including the living room, kitchen, and dining area with a vaulted ceiling my calculation for the total cubic feet is 5660.
My current sub is a VTF-2 MK-3. Is it going to be badly underpowered for a listening area that large? I am guessing probably so. If this is the case am I better off getting a second VTF-2 MK-3 or upgrading to a VTF-3 MK-3? I am more inclined to go with the latter.

That's a tough call Andrew! If you want smoother response at the listening position and across multiple seats, then adding a second VTF-2 MK3 would be great. If you wanted to maximize sound pressure level and wanted to use only one subwoofer, then upgrading to VTF-3 MK3 or VTF-15H would be great too.

Sincerely,
