Default Help with speaker repair

I recently got a, as it says on the speaker, 8812 C Linear Phase Studio Monitor at a garage sale (see pic). I ran speaker wire (plain old kind that would work with say a bookshelf stereo) to it but am only getting sound out of the top tweeter. I am using an older Harman/Kardon 730 twin powered receiver for juice (see pic). It has 40 watts per side on it. I plan on using this setup for a vocal moniter for practice. Are the other speakers just shot? Does it require better speaker wire? Not enough power? I checked that the speakers were hooked up on the inside and the cones and speaker look intact. The receiver has 40 watts per side. Please help!

Todd

Either the drivers are blown or some/all of the crossover parts are blown.

You can test the drivers if you get access to their terminals with an ohm meter.

They look like classic white van speakers to me, don't waste too much time and money on them.

I think these were the original white van speakers, well in Australia they were anyway. I agree, don't spend too much time on them. Pull the woofer out and measure across the terminal with a multimeter on the ohms setting, it should be somewhere around 6-8 ohms. If it doesn't give a reading it is burnt out.
