Hi Jennifer.
My A/D/S speakers all connect to a (well hidden) crossover. If yours are the same you probably have one channel powering more than one set of woofer/mid/tweeters. In that case the crossover could be suspect as well. Three things to try:
1. Gently press in on the speaker cone with your hand by placing all your fingers evenly around the midway between the rim and the center of the cone. The objective is to press the cone straight in evenly.The speaker cone should move easily and quietly . You should be able to depress it up to 1/4 " depending on the size and construction of the speaker...Use great care here!!. If there is any scratching sound the voice coil is probably damaged.
2. A quick check could be done with a 9V battery. Check the voice coil by intermittently attaching the battery to the + and - terminals...first +to + then + to -. You should see the speaker cone move in or out depending on the polarity of the hook-up. If it moves freely and there is no visual damage to the cone it may be alright.
3. If that all checks out OK I would power that one speaker with a known clean source to determine it's performance.

As you may have found out already A/D/S is no longer in business but there are a number of brands that would work well as replacements.
