the B&C unit uses a 2" voice coil coupled to a 5" (paper composite) diaphragm, much the same way as the RCA MI-1428 field coil driver of yore (build from the late 1920’s, if I’m not incorrect), the vintage driver B&C has sought to more or less replicate with the DCM50. As implemented in my speakers the sonic result is wonderfully uninhibited, unflappable (at any SPL), insightful, and naturally warm.
Much of my source material (uncompressed CD track rips; no SACDs or vinyl), are 60s pop, r&b and soundtracks, which were often victims of excessively applied compression. And some tracks during multi-vocal passages and when orchestrations get busy sound “congested”; possibly due to poor miking/baffling (??). So, while not outright crappy (??), much of my music was certainly less than pristinely recorded and/or mastered, even though almost all were issued by major labels.
Therefore, how enjoyable or "listenable" would beryllium drivers, especially like https://josephcrowe.com/blogs/news/...river-test-review?_pos=3&_sid=e989429b4&_ss=r make much of my recordings?
Ditto this beryllium https://www.usspeaker.com/radian 745neoBepb-1.htm , though which doubtless Pierre had perfectly EQed? See posts #15,266, 15,276. https://www.diyaudio.com/community/threads/beyond-the-ariel.100392/page-764
Might you instead recommend the "neutral" sounding Yamahas JA6681B aluminum, with beryllium support "fingers". https://www.youtube.com/watch?v=0LMJ-vbxIxA&t=358s
Or the perhaps more likely the "warm" sounding B&C DMC50 paper cone?
