Jeff, in line with Dean's suggestion, if the speaker wire is now connected directly to the upper(mids/treble)terminal, connect it instead to the lower terminal to see if the bass appears and everything else disappears(if it's already connected to the lower terminal, then that ain't it).

Excellent suggestion John.

I’m curious if it turns out that switching the binding posts moves the problem to the other set of drivers would bi-wiring or bi-amping be possible solutions or would either one or both of those risk the receiver or speaker drivers? Just wondering in case Jeff can’t fix it in another way.

Premature wondering, Dean, but sure, bi-wiring would by-pass the faulty(??)connecting strips and might be the first instance in audio history where an actual audible benefit was found for bi-wiring.

I'd probably just wire from one terminal to the other, but I can't imagine the bridging straps being that defective. They'd have to alchemically transform into non-conducting matter.

Yeah, Ken; you're right. To prevent an embarassing resort to bi-wiring, the one wire could simply be run through both the upper and lower terminal. But as you also say, it seems unlikely that the connecting strips are fatally defective.

Yeah, Dean, but if the low frequency section of the crossover is defective, no external changes in wiring can remedy that.

Edit: okay, you've realized that.

I just checked and the speaker wire is connected to the lower terminal on both speakers. Since one of the speakers works perfectly fine, I would think the issue might be inside the speaker. When I get back from church, I will probably try to pull the woofer out and see if a wire is loose.

Another thing I thought about doing is taking the speaker wire off of the banana plug and connecting it directly to the terminal. Not sure if that will work but it might be worth a shot.

I would try a bare wire connection as you suggest- it can't hurt to try.

Let us know what you find when you pull the drivers out. sounds like worst case scenario is you may need a new crossover. Have you been able to get in touch with the person who sold you the speakers?

good luck!

It seems strange for this to happen to BOTH fronts. I wonder if at some point, the original owner may have taken the bass drivers out, then wired them wrong when replacing them. It seems strange for BOTH fronts to have the SAME problem.
