Help With Peavey Bass Cab
Well, the drivers are all in parallel. I would have expected two of them to be in parallel, and then those in series, or similar...The the impedence of all of them togehter is the same as one driver.

Does it say something like 8 Ohms or 4 ohms stamped somewhere on the magnet or frame on the drivers?(that's the iimpedence.)
If they are 8 ohm drivers the load on the amp is 2 ohms-pretty darned low.
If they are 4 ohm speakers then it is a load of one ohm reallly low...

BUT they still should move the same amount.

I also wonder if both input jacks really are are wired the same and as you show....

Anyway I'll wait for other's input, and if no one has a better idea I'll try to make a drawing on how I suspect they want to be hooked up.

I note in an earlier post that you said they were in parallel, and they are. Also 16 ohm speakers in parallel would end up as 4 ohms- that might be OK...Any reason you think they are 16 ohm?

MAybe you should try switching the 2 non-moving much drivers with the moving ones (electrically by just moving the wires is OK)- then see if the non moving start moving and the moving stop moving as much.

ok well i said i think the speakers are 16 ohms because i tested them with a really ghetto multimeter and it came out to around 18-20 ohms so i just assumed it was 16 ohms. I also rechecked the inputs and there are like i drew. Lastly i did also try swithing the speakers and the same thing happen, the top two move alot more than the bottom two

oh and as far as the independence of the cab, 4 ohms is the best because the head operates best at 4
