I built a box before I chose a sub, so I ended up having to match a sub to the box. Luckily, I had several options, but ended up settling on this Vibe Space 12" guy. I was looking for sound quality first, then flash, and honestly wasn't too sure about Vibe as I've never heard of them. But I figured I'd give it a shot, and if it sounded like junk, I could always return it.

It didn't.

I don't know how it compares against other subs in this price range as far as loudness goes (it gets loud enough for my needs) but I was pleasantly surprised with the sound quality. It isn't muddy at all, and looks pretty sharp. So far I'm happy, and I'd buy it again, it's a solid sub for the price.
