thanks for your information.

hi, everybody,

There are blue and black version of some JBL compress driver. e.g. LE85, LE175. Who knows the difference between the different version? Which version sounds better?

Thanks in...

hi,

I found Cannon sold their aftermarket diagram for JBL LE85 compress driver. It seems to be cheaper than JBL's part much more. It's titanium. If I replaced my diagram, it will be an option.

Thanks all of you for your help.

I dismantled the rear cover, diagram and re-installed the diagram carefully yesterday. I'm very lucky, I think, the le85 does work perfect without any problem.
...

Thank you, I'll try it carefully.

Thank you for help.

Do you mean if I'm not careful, the diagram will be damaged because of the magnetic force? How about I use a plastic screw driver?

hi experts,

Recently I found of my le85 driver had a little bit problem.

One problem is its impendance curve is quite different with another one.

And it sounds a little bit lower than the...

its Re is 5.6ohm, but I don't know how to measure Le. Would you please point it out for me?

According to the impedance curve, is it not the oringal diagram?

Here is one of my 077's impedence curve.

sorry for this large picture. It's the first time to load a picture.

I tried to find the -6db point of an air core inductance(for example, 1.5mh) which its -6db point isn't exact the .75mh and then tried to make a line-out from the -6db point. It seems it works like a...

Giskard,

Thank you for your information.

Dear Giskard,

Last time, you told me the circuit diagram of LX5 and n8000. I tried it and it works better than the one I designed myself.

Now another question is I find there is another 3115A....
