2 x 10 cabinet One cone works, one doesnt

[Secret Journey]

Hey guys. OK I have an old Eden Metro 2x10 combo amp. I recently decided to play thru it again.
I only hear the bass coming from one side. I open her up, sure enough only hear cone on right. I take both cones out and switch them, still only sound coming from right side.
So, both cones work, all connections seem to be fine, so what is going on here? Thanks for any input!
Very basic schematic, is Right side cone gets the incoming sound from the speaker out(black an white wire), right side cone then feeds to the rear(one double black wire, one single black wire going to rear, one white wire going to rear, and one white wire going to left cone.)
Left cone has one white wire coming in from right cone, and one white wire coming in from rear panel (this is where all those left side cone wires went.)
Thanks guys for any help!

You probably shouldn't power it up anymore until your sure it's fixed so you don't damage anything. A picture might help. It sounds like a wiring issue. How long do you suppose it's been like this?

Not sure warrior how long its been like that. I do know I stopped playing thru the amp because when it warms up,(like an hour or two) things start to get funny sounding. I am the original owner(1998), and know that I should probably send the preamp/poweramp section out to get serviced, but not sure if it is worth it financially speaking. It was a great amp back in the day.
I now keep it simple and play thru the VT pedal into a QSC 2450, into a 2 x 10 cab, that rig sounds great. I will try to post up a pic of some kind.

I tested something else too, even when I bypass the pre amp, still only one cone works. hmmmm..

I would start isolating the problem first. Check that the problem is not the speaker.
Put a 9V battery to the speaker terminal. Check is the speaker's diaphragm moves. Do that with both speaker.

If both drivers work, it's a wiring problem. I'm confused by your wiridn description. Is the cabinet wired in stereo? So that you have separate inputs from the amp to each side of the cab? If so, are you feeding a signal to both the left and right channels of the amp? An amp channel with no input will have no output.

Otherwise, I'd expect to see 2 wires going from the input of the cab to speaker 1, then 2 wires from speaker 1 to speaker 2, or 4 wires from the input to the cab, one white and one black to the left speaker, and one white and one black to the right speakers. Sounds like there are more wires than that . . .
