Vintage Polk M5 Speakers (static noise / crackling noise)
just moved into a new house that had existing M5 speakers. Getting the surround sound set up, I hear static / crackling noise coming from just the front left speaker only. I'm new to this and was wondering what causes this? Are the speakers just old and probably been overworked? Or something else to check?
Thanks in advance for any help!

Welcome to Club Polk.
The Monitor 5's (M5) are nice vintage Polk speakers and quite sought after. There were several variations of the Monitor 5 from the late 70's through early 90's. Not sure if you are familiar with these speakers but the bottom speaker is a passive radiator (non powered), the middle speaker is a mid-woofer and the top is obviously a tweeter.
Have you tried making swapping the speaker left and right to see if it is the speaker or the amplifier causing the static? Is the static coming from the tweeter or the mid-woofer? Are the wires secured well?

Stan,
Thanks for the suggestions. I will play around tonight, and let you know.

Another thing to check if you are still at a loss... Gently and evenly press in on the mid-woofer cone to make sure that it is moving freely. Sometimes the magnet can shift and cause voice coil rubbing or even lock the voice coil.

Wish I would find some Polks while moving into a house. As stated above, try a little trouble shooting and see if it is the speaker or something else in the system.
