Post Subject: The RCA 1443Posted by Romy the Cat on: 8/9/2009

If the RCA 1443 the same as 1428B but without the field coil then it might be even more interesting than 1428B. As I understand that those prewar driver had phenolic diaphragms that generally shall have tendency to be a bit soft with low order filters. The field coil would soft them even more and probably perm magnet that do not “sink” would be better idea. I do not know diaphragms Steve and Rich use - I think it was carbon fiber… It is interesting that you feel that your RCA driver begin to breathe when it driven lover. I wonder why it is so. Is the cone over-damped that it does not feel free unless you stress it with LF. How does it work with very low level signals? How the subjective perseption of the driver’s HF knee changes when you move the crossover from 600Hz to 400Hz, or go second order with 400Hz? Sine you have both 1443 and S2 it would be very interesting to put both of them in respectfully best configuration and to observe how and much each driver will be able to go into depth of own expressivity. That what is what the audio idiots shall be doing during their congregation but they instead are mostly participating in there in the mutual audio dicks inner-sucking …

Regarding the Jeffrey's comments to you about the horns. As we can see it turn out that it lead you to discover a driver not the horn. So, it looks it has less to do with horn then with driver. So, it you cross your RCA 1443 at 350Hz then it will not run all the way up and you would need one channel above and two channels below… Is it what you are trying to do?
