Speaker impedance varies with frequency, so the ratings you're using are "nominal" or average, and you can't expect them to match a volt-ohm meter. But if you measure the same way they should measure the same, and they don't, so something is wrong. In other words probably not just the amp that's blown.
Impedance change!?
Hi,
I'm after some expert advice :)
I got hold of a pair of Celestion15s recently and they blew a channel on my Sharp SM1122 amp (it was my Dad's) which accepts 4-16 ohms.
Impedance is a rock solid 5.2 ohms on one speaker, and a wavering 11 ohms on the other (so it's highly suspect!) The label says 4-8ohms.
I've googled of course, but can find no reason for this difference and would appreciate any input on how I can resolve this issue.
Kind regards,
Paul
