Speaker impedence question.

[Ice Man]

I recently had a blown speaker in my Mesa 4x10. It's wired series-parallel, all 8 ohm. If I had the same thing happen during a gig and was able to identify which speaker it was (or which of 2, which was the case this last time...2 were vibrating badly), is there a way to take out a speaker or 2 and have 8 ohms remaining so I can finish the gig?

Thanks

Not exactly. If you wired the remaining three in parallel you'd have a 2.666 ohm load. And if you had a switch to select the impedence on the back of your amp you could probably safely finish the gig in the 4 ohm setting.

You'd have alot of quick unsoldering and soldering to do during your 20 minute break! :laugh2: Unless your speakers have slip on connectors...

Or if he had a stereo cab he could just use one side with the proper Ohm setting
