crossover help

[mbailey]

I've got an old MTI Rotophaser (Which is basically like the top half of a Leslie cabinet) That I am trying to restore. Cant find any info on the web about it. Any way its basically a high Freq. driver. It has a built in x-over that is supposed to send the high freq. to the driver & the lows out to an ext. cab. My problem is I don't know much about x-overs & not sure where to connect signal in and lows out to cab. I've made a simple drawing showing what i got. If someone would take a look & help me out I would be sincerely Appreciative

Do you know the frequency range of the driver? If it will take the upper mids you could simply put a two 47 mf back to back on the positive terminal to provide the band pass paralleled off of another full range cabinet. If it is more of a tweeter you would want to use a 4.7 mf or a 2.2 mf capacitors.

it has a xover I just dont understand how to wire it

Can't tell by that drawing. The inductor connects to nothing. One side of the horn connects to nothing. The caps originate at one place, and split to two terminals that look like you have them connected together.

Did you follow traces or wires inside to see where these unresolved leads go?

If it's a x-over, then it should have one input, +/-, and two outputs +/-. The inductor should have common connections to a cap.

Unless it's all supposed to be jumpered from the terminals, which may be possible.

Welll xover 2 should work but I think it should be like xover eg which would look like xover 3 ...can you get the original schematic ?
