Celestion SL6S crossover.

[docjoe]

Hello everybody there!

I' m looking for some plans from a Celestion SL 6S or Si crossover.

I have a pair of SL6 copperdomed speakers with fried domes.
and I own a pair of Celestion SL700 alu tweeters.

I'm wanting to rebuid the SL6 with the 700's tweeters.
But due to the increased efficiency and different beheaviour of the alu dome, I have to match the high pass section to the existing low pass.

can anybody help me with a schematic ?

I would immensely appreciate any return.

If they are compatible (the two tweeters) why don't you use a variable pad and translate the reference values to the fixed resistors, after you adjusted for the right attenuation.

hello Inductor. thanks for you answer.
I know the method of padding down a tweeter...I just want to check if they modified the high pass as the alu tweeter may have different HF ringing modes beyond 20.000 as metal domes ususally do;
maybe the ingeneers at Celestion implemented a notch filter for HF peaks ...
just curiousity.
and comparison with the SL6 filter.

best regards
jo.

really no one to help me ?

Ringing modes would be bad, and easy to check as you say, from looking at the xover, and not very pro. Why don't you post it.

Any luck with the crossover schematic?

No, but I've put the alu domes whitch matched well and padded down the output wit a resistive patch.
I finally got rid of the speakers, a friend of mine had them in his children's room and the children are happy with them. 🙂
