It's better than a Marten Supreme because the mid is cut off @500Hz whereas Marten cuts it off at 1,3kHz  "where the ear is at its most sensitive". Note: they must be referring to latest technology ears -- not the traditional ones (i.e. the ones most people on this site probably use). Whatever, if you say so.


That 2,5" ceramic must be doing a hell of a job playing well at 500-600Hz up to I-don't-know-where (5-6 kHz ?)...
Anyway there it is for your casual perusal.


The true reason why they do this is probably the very poor behaviour of the ATD from 1kHz up. CSD below is truely state of the art. I ask myself if their remarks about standard crossover means they use elliptic x-over, but if they did this it would have been possible to cross higher. Does anybody have information about the diamond midrange? Could it be used up to 20 kHz (with poor dispersion)? Accuton website still says available soon. That they use the Supravox in such a speaker (and no diamond tweeter) could be very interesting for high sensitivity people.
