risks of running an 810 as a 710?

[hyp.spec]

So the bottom right speaker of my Ampeg 810 is shot...

are there any major risks of just disconnecting that speaker until I can get a replacement?

I've got a gig tomorrow and I dont think i'll be able to get a replacement in time!

Thanks

You will change the impedance of the cab and lower the wattage it will handle by 1/8th. Possible damage depends on the head you're using and how hard you drive it.

Hmmm, It wouldn't be a 4 ohm cab anymore. Since the speakers are 32 ohms each, and wired parallel if I am not mistaken.

[hyp.spec]

its a 500w Little Mark III which is solid state and I'm assuming shouldn't have issues. the MarkBass 610 is 5.3 ohms... which is about where mine is as a 710..

I've heard mis-matching impedances w/ tube amps is a bad idea

Disconnect both speakers in that compartment.

If you are using a solid state amp you will be fine. Taking out that speaker entirely just raises the impedance of the cab, which will make you get less power from your head but won't damage it at all.

leave the bum speaker in while you use it, otherwise you might end up blowing the other one in the pair. but it should be fine.

+1. If you don't the second speaker will be acoustically unloaded and could be easily damaged by over-excursion.

I'm slightly confused.

Should I

1) Disconnect just the blown speaker, but leave it installed in the cabinet or
2) Disconnect the 2nd speaker in that chamber, making the cabinet a 610

thx

good question! when i had problems with my speakers, i disconnected just the blown speaker and left it in the cab. don't know if that's the right way or not but it worked for me.

[JustOpenYourMind]

It really depends of the wiring of the cab,

If the speakers are all in parallel, there shouldn't really be a problem (if you use a solid state head).

If they are wired as pairs (each pair in series and then all of them in parallel), you'd have to disconnect both speakers in the pair or the other speaker will be taking twice the power it is supposed to.

safest:

Disconnect both the damaged driver and the other one sharing a compartment with it, leaving you a 6x10.

probably won't damage anything, but might, and provides no real benefit:

Disconnect only the damaged driver.

Whatever you do, tape off the loose wires. You don't want them to rattle around and contact each other, shorting out the whole works.

[hyp.spec]

I'm not exactly sure how its wired... all I know its a 90's model.

I've been playing it at low volume at home with 7 speakers and it sounds fine... although if I cant find a speaker by tomorrow i think i'll do the show with just 6... just to be on the safe side!
