I can't help with the model, but it appears the owner created a system to enable the speaker to be biamped. I don't believe I have ever seen a KLH that was set up for biamping from the factory. Take a few more pics that shows the overall cabinet that will give a general idea about size and dimensions.
You'll need to open them up - meaning that you need to remove the drivers and trace the wires back to the black and red terminals. As others have said, the speakers are not really KLH any longer so you can't make a$$umptions. That includes that the drivers are, indeed, actually operational at all.
From the pictures, it appears they were modded for use as a portable sound system of some sort. That spells 'potential abuse' in my book. KLH home speakers were never designed for that application.
Thank you for all the replies.I took it apart and the connections are to the other leads not the red and black.Hooked them up and sounding great.All insides look original
You might want to hold off playing them at all until you investigate the guts. It's possible they're set up for bi-amping with active, or at least external, crossovers. That would mean potentially no internal crossover and the possibility of damaging the tweeters with low frequencies. It's not likely they're set up like that (it would be overkill on these), but clearly something strange has been done.
You should be able to connect to either set of black knobs, but leave the blue jumpers attached. As long as both speakers are wired the same, they should be in phase.
FWIW, if they were mine, my priority would be to identify KLH model. If they are Twenty's they are 4 ohm. As mentioned before, they resemble Seventeens too, which are 8 ohm.
Is that a "23" I see on the woofer? Could be Model 23.
And, those surrounds look like they are thirsty! If you keep these, look into the surround goop sold by vintage-ar on the bay or our own RoyC. A search will reveal all.
Perhaps a Frankenspeaker, then. The tweeter cutout on the baffle is intended for a round driver.
The OP's going to have to dig into the guts of these, or just enjoy them for what they are. They probably sound good!
