I own all SVS Ultra speakers. 2 towers and 3 bookshelf speakers for my surrounds and center channel. Love them. I kept an eye
on their outlet and got great deals on the whole set. Most have some kind of imperfection, but some are so lightly or barely nicked that you'll have trouble finding the mark. Just make sure to check the images they include on the page with the speaker(s).
I started with a stereo pair of Ultra bookshelves (fell in love immediately) I got for 399 apiece, then a third for the center, then eventually the towers all over the course of 6 or 8 months or so. In total I saved about 500 bucks going that route and don't regret it one bit. The same return policy and warranties as new apply too so there's really no risk either.
Using a sub in a small room like that I'd go with the bookshelf speakers. Even in my big room the towers are a little superfluous with subs, but I really wanted them, lol.
