Default Some information please

Hi Everyone,

I have aquired some old Seas Kit303 loudspeakers and although i have the brochure i need details of the crossover.

Does anyone have a schematic?


Thanks

Some data & crossover frequencies here:
http://www.troelsgravesen.dk/33FWK_f...t_Brochure.pdf
if you have the model numbers you may be able to find individual driver parameters here:
http://www.seas.no/index.php?option=...d=29&Itemid=53

that would be enough info to get a basic crossover together, but if these are old drivers you’re best to measure them anyway, their parameters have probably changed over the years

Thankyou, i have the brochure that you mention and am in contact with Troels whch is why i need the data for the crossover.

A little more information..the kits are working well but the bass drivers were not original and after speaking to Troels he suggested a replacement. Although these seem ok, i feel i need to change values slightly on the crossover and to do that i would need the inductor values, although i guess i could measure them?

Anyway thanks for your help.
