Hi, I was wondering if anybody has the impedance curve of a jbl
077/2405 as found in the L65.
This because of the fact that in these speakers they are crossed over at 6500hz; 12db/oct. I might want to try to put an LCR on them to neutralize the impedance peak and then hear what it gives.
Thanks,
Wim

Well, I don't currently have an 077/2405 otherwise I would run a curve for you and post it :(

Here is one of my 077's impedence curve.

Thanks chen_sp! :)

Any chance you measured the Re and Le of that 077?

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?
