Yeah, those are bi-wire terminals. The Type B wasn't designed for active bi-amping, so all you need to do is run a single length of speaker cable to the low terminals, then bridge those to the high terminals with a very short piece of cable (like THIS
, but you can just make your own for next to nothing if you are so inclined). Then you are all set.
If you can find the correct replacement for that KLH woofer, then all the better. However, it is possible, I suppose, that someone actually did some research and found that it was a close match. Hard to say.
