I currently have a Funk Audio 15.0 sealed sub and while I do like it a lot, I really think a dual setup is needed because of my floor plan. Also, ported cabinets seem like they are a better choice again because of the "openess" of the room. I've had my eye on a pair of PSA XV15s, but this would mean selling the 15.0 which could be a tough sell in a small town like mine. A second 15.0 is on the radar, but will result in a greater cost than dual XV15s and potentially less gratifying because of the sealed cabinets. I know I'd be happy with the performance of a dual 15.0 setup, but I would also be curious on what the XV15s could have offered as well.
I always seem to struggle with decisions like these. What would you do?
