So I'll tell you what I know.
They can take a ton of power though I've only been able to give mine 150 or so.
They don't go too low, think 75hz-90hz as a x-over point.
They kick ass in the midrange, they make snare drums sound good and tight.
The Manual says 275max, they might take 300 but I dunno if I'd do that for long periods of time.
