You can find the powered M1s for $299 I believe.
I think yeeck might be a fair statement especially if you set them up next to Blue Bears Adams, but in the $400 range they are surely better than computer speakers - I'm assuming your price range reflects an upgrade from a lesser model or computer speakers. Maybe you're looking for a 2nd pair of monitors - in that case then I don't know if these are what you want.
It also matters greatly what you have ahead of the monitors coming from your DAW - I just got
a DAC-1 and am about to set up my sound room again (I've been moving) and will throw the M1's on just to see what the improvements are - I think the clarity in the mids will be night and day - we'll see. I think I'll end up with
a Dynaudio BM6A pair though - I'm about 2 weeks away from that step. Then the M1's will probably go into the home theater.
These guys are double bass ported too so I guess that means they leverage all they can to get the bass to balance as well as possible from the confines of the cabinet size they've chosen. You EQ the bass and lomids (< 300 Hz) by stuffing the ports and positioning within the room and room acoustic adjustments (as with any monitor).
So I can say I haven't really heard these guys yet since stuff in my chain just wasn't providing a great signal - the DAC-1 should fix that - but still these guys are $300 monitors so they won't stand up to Adam, Mackie, or Dynaudio that are in a different catagory and I just don't know if they have enough detail and balance to get masters to translate the way I want at this point. They are a heck of a lot better than computer speakers and would be the next rung up the ladder - I'll say that.
