I think they look really nice, and I'll bet you can coax some pretty decent performance out of them in your room. You don't have a big room, right? I'd be experimenting and comparing to see if I get a smoother response having the 2 of them over a single sealed sub, or even an interesting opportunity to compare and contrast the *gasp*
musicality between sealed and ported!
Seriously tho, the Cantons may not dig as deep but I'll bet with a li'l tlc you can get them to sound really good in there!
