Hello Allen,

Welcome on board.

You should "register" your equipment in your signature, so it's easy to respond.
Regarding your cards make for each card a better high resolution picture and put in the gallery. You can check now the EPROM look at the printed label.

Did you retype each speakers two times before you tried it?
What about soldering?
Do you check the connectors?
What about the power amps?

There are printed label somewhere on the power amps that telling you the serial numbers of the electronic-not of the firmware.

Play both speakers in mono if you have a processor or setup both speakers as left or right so both speakers have the same signal.

Be careful with the screws, some are screwed in to the chassis/wood, so do not over tighten or unnecessary mounting.

Reinstall the new firmware before you do some hardware, it could be that you have to do it 2 or 3 times.
