meant can you swap 8 ohm for 16 ohm diaphram and my other question is, would it still retain the sweet sound the 77 is known for the only difference being 16ohm impedence? Thanks

Yes you can. They are actually identical no matter what the foilcal on the driver says.

If we knew what the hell we were doing, we wouldn't call it research would we.
Right. You wont need to swap the diaphragms. Actually the AC impedance is right about 12 Ohms on all of them.

Thanks i will use these 077s on my unique 16ohm setup. 175 Le15a and add 077. Just looking for the right crossovers and trying to find the correct plans to build the right boxes for them. Barry what do you know about the 076 cats eye bullet? Anything special sonically speaking?
Barry if you dont mind the extra questions. Are you familiar with the LE15 woofer? One came with foam surround 16 ohms and the other i seen in L200 system paper accordion surround at 8 ohms. Would that 8 ohm le15 still be 16 ohm regardless? I want everything 16ohms in my new project thats why asking. Lastly whats the perfect crossover for the le15a 16ohm..thanks agaian
Hi Vinny;
I don't mind at all but that's a question I don't have an answer for. Hopefully someone that knows will chime in.
All the best.

Why don't you take a look at the L300? It's a modern update of sorts of what you are considering and sounds considerably better. There are some useful threads here on site including crossover schematic (search).
There are too many variables for me to give you really useful info.
I agree with the poster above, the L-300 is a great starting point. If you can't get those parts all lined up then try cloning a JBL that has the parts you do have.
In my opinion JBL has gotten better and better over the decades so a newer design will likely offer better results, though there is a lot to like from each decade.

thats not what i been hearing from the groups that ever since 1979 when they went to ceramic magnets and cut costs they regressed and tTad has blown right past Jbl in construction and sonic quality. Its now relegated to mediocre stature in their drivers. Paradigm even makes better drivers than modern jbl which is just living on its past reputation.
