Hi Sean. No, I do not know EXACTLY what driver is used in the Eclipse. Actually, I am not that well versed on their new speaker models. Sorry. I did go to the Coincident website for you, to get a look at the Eclipse midrange drivers. I do know that Israel likes Seas midranges, so I then went to that website(check their drivers out at: http://www.seas.no/seas_line/oversi.htm). Sure enough, it is a Seas. The three models I found that could be your 5" driver(all 8 Ohm Z) are: 1).MP14RCY, a midrange(100 - 4000 Hz, 90 dB, 420 g magnet). 2).P14RC, a woofer(45 - 4000 Hz, 89 dB, 250 g magnet). OR 3).P14RCY, a woofer(45 - 4000 Hz, 90 dB, 420 g magnet). Of the three, I think we can factor out the P14RC(for obvious reasons). I would also venture the guess that yours would be the MP14RCY(as it is the midrange, has the larger magnet, and the 90 dB sensitivity). Be advised that Israel often gets the manufacturers to install larger magnets on his drivers(only a big plus for you!). If I were you, I would definitely contact him about the drivers. The worst he can say is no. If you don't ask him, your answer is no anyway... He has always been a straight shooting, open, and honest guy. Tell him your situation, that you are not competition, and what your goals are. Be honest, don't BS him. I think he would be much more open than you suspect. I would even ask him for the crossover values he uses in the D'Appolito configuration of the Eclipse. I also think he would recommend the ScanSpeak Revelator for ultimate performance(or another for a less expensive project). Sorry, I could not give you the inside dirt, but I hope what I have given is of some use to you. If you contact him, please let me know. I would like to know his answers. Good Luck!
