Post Subject: DCM50 and 1428Posted by Romy the Cat on: 11/18/2013

Thanks, Kerry. It was interesting. I never used neither RCA1428 driver nor it’s clones. I heard them I think once at Oswald Mils. It was for sure a pleasant midrange but it was nothing else wothe attention in there, so it is difficult to say anything. I hear a few times the Congent clone, I was not wild about the results but it might be the way in which Congent used their MF driver. I was not agree with their other design decisions so who know why the MF did not sound interestingly?

I never heard the B&C DCM50, it might be ended an interesting driver. I do have high respect to Bill Woods even though I disagree with some of his conclusions and even though he is associated with idiots in his business. For sure if the DCM50 has different diaphragm, different phase plug and a different motor then it is not the RCA1428. The center suspended paper diaphragm is very interesting however, even it have own design controversy.

I never heard the Herr Von Langa drivers. Any’s is trying to solicit me to do to South Africa to visit her brother who work in there as astronomer and if I do I might meet Von Langa and see what he does. So far , on the specks, I am not wild about his field coil conversions. He uses high current low voltage configuration but my observation of those type of the drivers suggest that they are too slow to me. I would be more interesting to hear 80V-120V drivers. However, if you feel that 375s sound tinny and artificial in comparing then it might be interesting. I do not think it is possible to find any common denomination in the drives evaluation unit we both listen the same installation and compare direct notes. It would be interesting to find a hypothetical MF driver that do the demanded job itself, with tonal injection, but I truly doubt that it might be possible, I have my reasons to feel this way.

Sure, if I hit the West Coast I would be gratefully to hear what you assemble, I know you have been experimenting with all of it for years. I do not have immediate plans to hit West Coast. For sure you will hear from me if I do.
