I have a pair ... but no time yet to try them out. I searched this forum, but it seems like there's not much experience with this driver yet.
AMT's are quite rare anyhow. I have tested a couple from Mundorf, I found their AMT2340 to be very good, although its not happy with crossover below 3 kHz.
I hope the Beyma can be crossed over an octave lower, so it can be matched with the 8" Seas Excel magnesium (which is great only below 1500 Hz or so)
Well... I hooked them up and measured them with my Clio (without any baffle). The response is not as smooth as one might expect, but not too bad I think. It will require a couple og LRC networks for EQ to get the response within 1 dB.
Ok, here are the measurements:

If anyone else would like to share experience with this driver, I would appreciate it a lot.
