so the top left speaker of my cab was blown. i replaced it with a direct replacement. after i hooked it up and tried to play thew cab sounded horrible. i took more speakers out and noticed the bottom left the negative was unhooked. hooked it back up. checked the polarities on all speakers. and it still sounds horrible. i noticed the top left speaker moves twice as much as the rest and it was doing this with the old speaker. everything is hooked up and correctly even checked with a 9volt. what can i do i cant afford another cabm right now

IIRC, an Ampeg 610HLF uses 6 ohm speakers, with each pair wired in series, then they're wired each group of two in parallel to the crossover/or jack. so 6 ohms+6 ohms (series)=12 ohms, and 12ohms+12ohms+12ohms (parallel)= 4 ohms.
you might want check again sure that it is wired that way.

i have checked and double checked. i honestly can not find anything thats wired wrong. everything is exactly how it was when i took the speaker out. every positive and negative wires are where they should be. the speaker is an exact match and an ampeg speaker. im stumped

well something's wrong and you should be able to find it easily if you spend a little time and test it methodically.
i would start by getting some alligator clips and just testing individual speakers, then pairs.
see if the cones are moving the same when going from pair to pair. it will be a 12 ohm load if each pair when they're in series which won't hurt anything.

all the speakers move the same direction when i put a 9v on the speaker cable. its just the top left speaker is driving me nuts and it seems the whole cab lost its balls. theres no low end at all. like i said im lost. what would cause 1 speaker to act like this. ive switched speakers out thinkin it could have been the new one and still does the same thing

just because all the speakers are moving in the same direction doesn't mean that it is wired correctly. you have to start at the beginning and test them individually.
do you know where i could find a schematic to be positive its correct? i dont have any kind of electrical testing equipment

you really don't need any test equipment.
the cab is wired series/parallel with each two 10's in series and then all the pairs in parallel.

call me an idiot but im still new to tinkering with ****. how would i go about making sure thats correct. how should all the wires be hooked up to each speaker. right now its the wire going to all the -s on the left and one to all the +s on the right and then wires connecting the two speakers in pairs

thank you so much for all you help by the way. that is how its wired. i checked to make sure every connection is tight. like i said i have no idea what to do

then you'll have to test them individually first, and then in pairs, like i said earlier.
it could be that your other 5 drivers are damaged, but i kinda doubt it.
after testing them idividually.
disconnect all but two of them, then observe and listen to it.
then do that with the next pair, and so on.
without being there with you, that's about all i can tell you.

Johnk_10 has it correct, I DO have the schematic!
Yes, 6 ohm version of the 86-610-04.
if one speaker moves a lot farther than the others, then one of two things is true......
1) the wiring is NOT what you think.
2) You have one speaker of a different impedance...... probably 16 or 32 ohms.
Since you think the wiring is right, look at all the part numbers, which should be on small tags on each speaker, probably on the edge of the magnet.
I bet the one that moves the farthest is different. Someone may have replaced it with one from a 810, which is totally wrong for the 610.
Was it an 86-032-01?

they are all the same impedance and part number. even the one i bought to replace the blown one and all the wiring is correct.
Try swapping the new driver with another one. See if the problem moves with the driver, or stays in the same location.
Edit: Then try swapping the driver that is paired with the problematic driver. I have a hunch that the paired driver may be the problem.

How 'bout trying a different head with that cab? Can you borrow one for a five-minute test? Even if it's a non-BG head? It's possible whatever "event" caused that driver to blow also compromised the amp you're using. It's a long shot but in my opinion still a worthwhile exercise.
Also make 100% sure your speaker cord's okay. "Working" does not necessarily mean "okay."
Also make sure all the drivers are socked down tight onto the baffle, no gaps, etc.
And if that wire fell off, does that mean the cab took a physical impact? I'm thinking of internal structural damage or misalignment, which would change the box tuning.
Does this 6x10 have a horn? If so, could be a problem with the crossover. Try taking it out of the circuit entirely. (Wire the six bass drivers direct to the cab speaker jack per John's schematic.)
Sorry, I know I'm grasping at straws...

the cab hasnt taken any major impacts. it has normal wear and tear. the speaker chord is brand new, that was the first thing i tried. I used my GK 1001rb with it and it still did the same thing. I noticed the tubes on my head wore out faster than normal. but this cab has been doing this longer than i have been using the head. It does have a horn in it. but all the wires are ran into a plug thats connected to a circuit board. could this be the problem?
how do i find out if that is the problem? and where can i get a new one if it is? and has anyone else had a problem with it?

Don't worry about finding a new one. That has nothing to do with your next troubleshooting step, which is eliminating your crossover from the speaker circuit.
(Just trying to get you focused. ;-) )
