Monitor 4 midrange speaker

[vinpolk]

I need help figuring out if my midrange speaker is blown. I switched it to the other channel and still the same problem-I get little if any bass response out of one speaker but the tweeter seems to be working. Is it a blown midrange or possibly another problem? I need to diagnose this problem before I buy another midrange.

Push lightly on the mid driver, it might be frozen. It is common that the older driver freeze up. In which case you will need a new driver,

Polk Parts, MW6503.

Jakelm-

Your right-it is froze up-these speakers haven't been used for 15 years and I don't know how they were stored. Looks like I'm looking for a new driver-any ideas? #MW6502
