hi, have u first disconnected the tweeters and then checked, as if its on a cross over, the tweeter is in series with a capacitor,if u have a ohms meter or a continuety tester check the tweeter coil if its open,secondly you can have the coil replaced, check if u can get one before buying a new,let me know

You may have a problem with either blown tweeters, or a faulty cross over, or both. If you have a multimeter, you can remove the tweeter, and check it DC resistance. They normally have their impedance marked on the back of the magnet. If not, you can assume they should measure 8 ohms. If they measure open circuit (high resistance), then they have failed.
A good speaker repair guy can often fix an open circuit tweeter as they often break where the very fine wires attach from the voice coil to the terminal. you can take a turn of the voice coil and reterminate to solve this problem. If the voice coils are burnt, they will need to be replaced.
If the tweeter meters ok, then you may have a problem with the crossover capacitors going dry. Generally they are 2.2uf to 6.8uf in value, the smallest cap in the crossover. If the plastic coating on them is split, or they look a different colour to the rest of the caps, replace them, if they sound "hollow" replace em, if you are not sure, replace em. other than that there is not alot more to look for with a speaker box tweeter Good luck and happy listening.
If you have any dramas, get back to me here and we can talk more about it.

Before you go throwing money at this problem, try to eliminate any external influences like track lighting. I myself am trying to figure out why mine makes a buzz throughout my system when the lights are on. I already replaced the variable light control with no improvement.
Bad cable ground can let airborne electronic noise into the Sub's amp.

KLH 900B tweeter specifications: 6 ohm, 40 watts. By the way, KLH's QC for speakers could be improved. One of my 900B tweeters quit because the spacing for the voice coil was way off reasonable tolerance and the body of the speaker coil base pillar (ie: magnitized part) was off-center - and cauesd the coil to ware and short. I contacted KLH but they did not respond.

You can use 4 speakers. Connect 2 speakers to the A system of the JVC and the other 2 to the B system. Then select in JVC the A+B speakers position. As your receiver is stereo, this is the way you could best distribute the sound. However, if you have only 3 speakers, it would be dangerous to try wiring the third one without changing the whole impedance. So you may use 2 speakers.
