Hooking up Electro Voice LR4SAT speakers

[RSMRecording]

I have 4 vintage Electro Voice LR4SAT column speakers (line array type) and need help to hook these up correctly.

These speakers have a voltage selector for 25, 70.7 and 100 volts line. I have a crown D-75 power amplifier that I planned to use with these speakers.

Hope someone can tell me what voltage line I should use.

Thanks,

Robert

Ideally, you'd open up the speaker (or whatever necessary) to bypass the constant voltage transformer. By doing so you'd run the speaker at a more conventional 6-8 ohms.

Thank you,

I bypassed the transformers and the speakers are 8 ohms and work great.
