Only the field coil voltage is different.

I am s...What did you replace these RCA units with?<br /><br />I am struggling to decide between JA6681B, TAD 4001 and RCA MI1428. Having only heard the JA6681B and being rather pleased with it, I wonder if there is any point in pursuing other drivers. I have been experimenting with a cheap siren driver called Federal Sound FS100W and was not at all pleased with its phenolic diaphragm in direct comparison with the aluminum diaphragm JA6681B and the Community M200, and I wonder if I am hearing something different than others, who claim phenolic drivers are the best on earth. These were however very cheap drivers. I should test out the JA6603 phenolic diaphragm to see if phenolic can sound superior. Maybe its the 5" size of the diaphragm that makes the RCA1428B such a great driver, since it can reach lower more effortless. The JA6681B can reach 250Hz, but 340Hz is more comfortable - just like I have read about the RCA MI1428.Jonny_1984https://www.blogger.com/profile/17642248744348802603noreply@blogger.com
