Just use a couple wires and a battery(ie: AA, C, D, or 9V), briefly touching the woofer terminals. You can do the same test with a multimeter, set to "ohms". The speaker should either push out, or pull in, depending on the polarity of the hook up. If it speaker has ever been stored in an area with high humidity: there could be rust in the voicecoil gap. If it's ever been dropped: the polepiece or magnet could have shifted. Either would hold the voicecoil captive, and eliminate it's excursion. If the voicecoil is burned: you'll get limited excursion, and a lot of rattle(with music).
My Woofer Sounds Like a Tweeter
I just pulled out a pair of mid-80's vintage Polk Audio bookshelf speakers from the spare bedroom and I wired them into a second system.
One of the speakers only produces the high frequencies from it. I opened the inside of the speaker enclosure and checked if any wires were loose or broken, but everything looked OK.
The tweeter seems to be operating normally, but the woofer is only radiating high frequencies.
These are not very costly speakers.
What is the problem and is it a worthwhile fix?
