I'm sorry to reply so late, I'm guessing you already made a decision and I'm curious to hear what you chose and how it has performed.?
Personally, my Dahlquist are on my three season porch and get double duty. Most of the time they only play music, but 2-3 nights a summer I host neighborhood movie nights and set up a projector.?
This year, I went big and bought two PB-2000 subwoofers. I think the sealed version would be better for music, but I wanted the big bass for movie nights and don't mind it thumping. I can turn the bass up or down pretty easily if I think it's "too much."
In your shoes, I would recommend buying a ported SVS subwoofer (model depends on your budget) and try it out. If you like it with music, you can get a second one. If not, the sealed version may be better for music only. If space is a limitation, just go ahead and get the sealed version.
Unfortunately I have no experience with the other subwoofer you mentioned, but I assume you've already made a purchase.?
