Counter perspective,

2x SB13-ultra. My money anyway. Or if gluttonous, 2x PB13-Ultra. But your room would be more than serviced by sealed units. Svs owns the online sub market. By a long shot.

I prefer sealed units by a mile, whichever way you decide. Waaaaay better.

Your room is not that big. Even 4 SB-2000s would be insane.
