Googling the midrange driver starts in the 40 floor stander…but doesnt reappear till the big centre..price 100000£I think these ATCs all share a 3" midrange driver which is what gives a really outstanding midrange, so I was wondering how good the much smaller, 'cheaper' models with the same midrange would also sound as good in that respect. You can make clones of the smaller speakers using the same drivers from Wilmslow Audio as I recall. I'd like to hear some just to see. It's the 'crackle' you get from the Behringers that is reminiscent of the ATCs and one element of them that makes them seem such great value. I have a spare B215 in white that I may experiment with one day - redo the crossover for a lower crossover point, and even try the drivers in a cabinet with a constant directivity waveguide just to see what that gives, but I need to be in the mood for that as it can be quite a time consuming project, albeit a lot of fun and rewarding.
