Request for Tannoy Cheviot crossover help

[daniel4381]

Dear daniel4381,

I don't know if I'm late, but the circuit diagram you have in post#1 seems to be the correct one, according to the following document, which is a database of all Tannoy speakers (till date):

https://www.hilberink.nl/tannoy/jpvanson/speakers.pdf

Besides, I happened to find the same circuit diagram from the following webpage (not repeating the picture here) and some more information on the HPD series:

Tannoy Monitor Crossover Circuits
hpd tech manual
hpd series


Don't know if that helps.

Thank you for the information. I'll try changing the caps now.

[STEP RESPONSE]

Dear daniel 4381
If you find frequency response and impedance measurements on HPD 315 A - of course without filters,
I can offer an original (unknown) crossover for Cheviot.
