The eD A2-300 is the most impressive home theater sub in this price bracket by a considerable amount. It has the ability to hit clean lows with authority that is lacking from every other sub I've heard in this range. That said, I think there are better subs for music. It's not that the A2-300 is bad for music by any means, but it's midbass doesn't blend as well as some I've heard. For a truly mixed environment, I really like the Polk PSW-505. My dad picked one up and I installed and calibrated it for him, and even as an A2-300 owner, I was very impressed. I had looked at some of the more recent Polk subs and thought they were way overpriced for their output, but the PSW-505 has the goods to deliver, especially at the $200-$250 price point. It still has nowhere near the output below 30hz that the A2-300 delivers for home theater applications, but is one of the most musical subs I've heard, and still has the capability to hit pretty low despite the falloff. I wonder how much additional output you could get out of a second one, if they could be had for $400? Anyone running dual PSW-505's? The HSU STF-2 is also probably a good suggestion for mixed environments, although I haven't heard one. I really like Hsu's and SVS's higher end options though for mixed media environments, but you won't be able to touch them for under $350.
