[QUOTE="Max Warasila, post: 212509, member: 3845"] The B&C design will almost certainly have better distortion characteristics. The impedance traces also clearly show a different design to the BMS. The B&C design also seems to promise a much nicer crossover region where both diaphragms work together, as opposed to the rather steep and sudden transition in the BMS driver. As usual, though, the BMS seems to be a touch louder, and seems to have more LMF extension. I also suspect the B&C will be easier to design a successful crossover for, given that you accept DSP correction (I whipped something up in about 5 minutes). My point here is that this appears to be a different design with different compromises and technologies for the same product segment. While there is clearly some IP overlap, BMS and B&C design their compression drivers in different ways with different "secret sauce". I think there's enough of a difference to say they are clearly different. I would separately object to calling the DCX a "Chinese rip-off" in any way. Besides that it is not manufactured in China, it's not significantly cheaper or of less quality. While the first coaxial compression driver for this segment was clearly the BMS, I think that B&C have spent major R&D time coming up with what they think is their best version of a 1.4" coaxial compression driver. Finally, I'll admit I'm a bit of a B&C fanboy, and would like to say now that I imagine the B&C will sound better in part because of the bias from my experience with the BMS 4594HE and several B&C compression drivers. While I was planning on selling my 4594HE, I am seriously considering waiting to sell it until I can get a B&C DCX464 to compare. P.S. Am I the only one having trouble reading "DCX464" and thinking "DCX2496"? [/QUOTE]
