strickly as a guess, and only listening to them minamal times...and usually with keyboard patches, I'd say they are as "flat" as you might need them, at this price break and size of the speaker. Just like any other speaker, you'll have to get used to them. I'd use them more as a backup speaker when I'd want something smaller, but certainly, they could be used as a main speaker in a small setup. If you go up to a little more money, you will probably find sets that have a better reputation and a more accurate low end. If they where great speakers (at what...$250 new/pair), they'd be selling like hotcakes. But, Alesis has sold a truck full of them, I'm sure. They're discontinued now, I believe.
