SOURCE: karaoke speaker,no woofer or midrange working, only tweeter
Hi, it's probably that the 8" woofer and the midrange of the "amped" enclosure is open. One way to test is to remove just one wire from the inside of the enclosure to the woofer or midrange in question and with the use of a continuity tester (or a VOM), check for the resistance of the coil of each the 2 speakers. Both should read anywhere from 4-8 ohms, if there's no reading (VOM needle will not move) then the coil(s) are open. In the absence of a tester, a single AAA or AA battery would do (pls. some would argue that this is not a sound practice, however this should be enough for you to be able to determine the condition of the coil(s)). With the use of the battery and a single short length of electrical wire, apply power from the battery to the terminals of the speaker, if the cone moves, then chances are it is good, if they don't then you would have to replace it. Am not sure if available in your area, but there are some trained people who can rewind the coil should a replacement speaker be not readily available. Hope this be of help. Please let us know how things turn up. Regards.

bhurajiv,
Well it's a good thing that you are getting sound from the tweeter from the speaker cabinet with the problem, that eliminates one of the possible problems; your wires are connected!
If your other speaker sounds fine, the first thing to try is to swap your speaker wires with the one that sounds fine. If the problem speaker cabinet still only produces sound from the tweeter, the problem is within the speaker. If the problem goes away, the problem is from your electronics.
If the problem is within your speaker and it is still under warranty, find a authorized repair location (http://www.cerwinvega.com/service_center.php).
Problems within the speaker can only be one or more of the following: 1) The drivers not producing sound have been blown; played with either too much power and/or distortion. Distortion is created when you play your music too loud with a amp not able to reproduce what you are looking for in sound, the speaker itself can hear it before you can.
2) The speaker cabinet has a crossover inside which directs the proper sounds to the proper driver. This crossover can have components that have been broken be either #1 or from exsessive vibration.
3) There are wires inside of the speaker cabinet that have been disconnected. This can happen over time or if someone reaches inside of the cabinet through the port and pulls on the wires; like a young child or pet such as cats.
If the drivers in question just one day stopped producing sound, start with the easiest solution, #3 then #1 if you can suspect anyone could have played your speakers other than you.
To diagnose the problem, you first start by removing the woofer and confirm that all of the wires are connected and in good condition. While the woofer is removed, to eliminate that there is a problem with the speakers, temporarily connect the mid-range and woofer, one at a time, directly to the wire coming from your electontics, if they produce sound the problem is within the crossover network, if they do not produce sound, the problem is with the driver itself. Replacement parts should only be purchased directly from Cerwin Vega directly (http://www.cerwinvega.com/contact_us.php)

SOURCE: Speaker act more like tweeter only, not mid range + tweeter
They are mid Hi speakers.1st Open them and check if the mid speakers are ok maybe they are defected or the protection is open. Good Luck Toufic Malek

Pull speaker so you can get to the terminals in back. Take an ohm meter and check the ohms of speake, a 4ohm speaker could measure up to 5ohms and still be good. If the reading is way off then it is blown. If speaker is good, then check the cross over thats in the speaker, some models put fuses on the units for protection, but mostley on the high frequency of the cross over, not the low.
