Selling Damaged Magicos

Very easy test, take a 9V battery, touch it to the terminals at the speaker, + to the red/positive terminal and - to the black/negative terminal, this should cause outward cone movement, if no movement the driver is blown.   In most cases of excessive power or DC to the voice coil the coil will delaminate or change shape slightly causing it to rub against the pole plate, it'll also have a slightly "burnt" smell caused by the lacquer melting because of heat.

To test for rub place three fingers around the circumference of the dustcap and push in gently, the cone should move freely.

Best of luck

What does the meter indicate on the 200 ohm scale when the test leads are removed from the meter altogether?

Assuming the answer is something other than the very low numbers mentioned in your last post, but instead is perhaps an indication such as "199" or "err" signifying "error", given the limited resolution and rated accuracy of the meter those results seem likely to be consistent with a resistance of a couple of ohms or so. Which seems normal and NOT consistent with a burned out voicecoil on the woofer. But I guess the next step, if necessary beyond Peter’s good suggestions, would be to remove the woofer and proceed as I suggested earlier, without disconnecting it. Also, when you do that measure the resistance between the + terminal on the rear of the speaker and each terminal on the woofer itself, and also between the - terminal on the rear of the speaker and each terminal on the woofer itself.

There is no change. It stays at 1.

If I were to list these for sale as is, what should I try to sell them for?

I'm not sure, then, that the meter is working properly.  It might pay to put a new battery in it, even if the low-battery warning is not being displayed.

The magnets may have come unglued and locked the woofers up also.... Can you move the cones?
