Genesis IM-8200 Question

Dec 3, 2018
Hi - Quick question. Bought a pair of Genesis IM-8200's that I am going to resell on Craigslist. Picked them up at a budget price from another CL ad, and then had them re-foamed by the OTHER Genesis guy (Human Speakers - he's local). Just have them hooked up to my midfi system - should have plenty of power to drive them. One speaker is significantly louder than the other - for example in vocals. The guy who re-foamed them did say he had to tighten up the binding posts in the interior of one speaker - so maybe they came loose again? But it's not the signal is dropping out completely. The other thing I noticed was a piece of electrical tape around one of the Bass Extension Fuses (which I guess would be removed if these were paired with the partner sub). Not sure if this would have any bearing on volume or not. I'd like to figure it out - so was wondering if anyone had insight. I am NOT one to tear apart a speaker to check the innards out, so if worst comes to worst, I guess I'll take them back to have the speaker guy look at them again. Just wondering if anyone had any obvious thoughts/input they could share. Thanks - geo.

These speakers are unfortunately so old (1993) that we don't have the much to go on. The original owner's manual should be on our website under "Archaeology". Here's a direct link:

The "Bass Extension" changes the Q of the high-pass on the woofer to extend the bass or not. Fuse in: more extension, Fuse out: less extension. It should not change the volume in the midrange.
