Ken,

Just curious, how could I misdiagnose? I removed all 5 speakers from the VP150. I tested the two high range speakers, one was 6.0 ohms and the other was 5.5 ohms, so they checked out as expected.

WIthout changing any settings on the DMM, I repeated the exact same testing procedure with the three 5.25" woofers. Presumably, all 3 should have read about 6 ohms, but all 3 were open circuit...
