Recently, the woofer in my left bookshelf speaker stopped working. The tweeter, (one in each cabinet) still work. When I switched the woofer in question with the right speaker's woofer, I discovered that it works. Is it possible that the 2-way crossover in the left cabinet is the problem?
I don't know which particular crossover (specs) to replace it with. The speakers are Advent Baby II bookshelf speakers.
Thanks in advance,

Re: Lost woofer in one cabinet.
I'm not familiar with your specific model, but some of these have fuses for the woofers. Check for a blown safety fuse. Also, verify that the connections to the crossover board are in good shape. These crossovers are not that complex and don't usually fail. Keep us posted on what you find.

If you are shopping for a quality pair of stereo speakers for music listening not only should you trust your ears but have a look at the individual components that makeup the speaker. The cabinet of the speaker should always be solid, knock on it with your knuckles and see how it resonates the sound. Preferable it will sound dead and solid; we want the drivers moving not the cabinet!
The tweeter: The tweeter is responsible for the upper range and should be made from a rigid yet light material that does not deform when moving quickly, aluminum, titanium and ceramic are excellent. Paper, silk, cloth and plastic are not good for replicating notes in this range.
The woofer, much like the tweeter the woofer must be made from a rigid light material. Yet the woofer reacts differently since it produces a lower frequency range. Paper aka pulp fiber and other fiber composites work very well, as does aluminum and to a lesser extent plastic.
Did you actually mean "all speakers... AREN'T working" except some tweeters? Crossovers don't protect the woofers. If crossover die all speakers they protect go silent due to loss of signal. Excess volume or distortion kills speakers and not always linearly.
If you said it wrong and some tweeters work, I'd suspect the latter above...
You (or we) could guess or you could take out one tweeter at a time and swap it with a (presumed) working one or just emasure it for dead short or open with an ohmmeter. If the tweeters check out and work elsewhere the problem would likely be within the cabinet.
The voice coil is open, you can look real close at the spider wires that are soldered from the two terminals to the cone to see if they are bad, otherwise you will need new woofer, you can try getting the woofer from partsexpress.com
the best solution I've found is this: 1. Remove all the tweeter screws. 2. Take a thing metal rod (a coat hanger should work) and lightly tap the tweeter through the top port in the rear until it is loosened and comes out. The tweeter is totally sealed so you probably won't damage it if you need to do this to a working tweeter.
This method also works for the woofer but you need to be very careful to tap the frame or magnet of the woofer and not the cone.
