Coincident with 8 ohm vs16 ohm

I have the Super Eclipse 3's. My cj Premier 12's (140W's with a 4 ohm tap) won't drive them- I don't think these amps really ever 'turn on' into a place where they are supposed to work. I bought a 30w cj Premier 11xs with a 8 ohm tap and it absolutley lights up the Coincident speakers. I had a similiar result with a 30w solid state amp- it worked great. I think a 8 ohm output impendece will be fine based on my experiance.

Kalan, I agree with your post regarding impedence:

"I would guess that some other factor is going on with the cj Premier 12's vs. the cj 11xs. In theory, all that's going on with lower impedance taps is more transformer windings in play."

I think my problem with using the P12's with the Super Eclipse 3's was due to the efficiency of the speakers. The P12's just didn't like to run with only a few watts of power output. My P12's drove my B&W N803N's with no problem and sounded great but I think they were within their desired operating power output while driving those speakers. With the very efficient Eclipse 3's, the P12's were idling and not sounding their best. I can push the cj 11xs and it's like a spotlight from heaven compared to the P12's.
