The bass and right channel speaker seems to have stopped working. I recently moved with these speakers, checked them onto an airplane. I worry that they were damaged in travel, but there appears to be no external damage to the speakers or to the bag they were in. Every thing was padded, and the packing was undisturbed. Could it be a simple fix, or are they seriously ruined?

Get your system to a repair shop! Note that the problem is in the PB9 jack at the back of the subwoofer and don't try to wiggle anything yourself - they're great speakers, don't do anything you'll regret.

I too had the left speaker malfunctioning. Luckily, i had the curage to open up the speaker and look into the problem. Before that i checked to see if the input inlet to the amp worked by plugging in the right speaker in the left input inlet. I was able to hear the speaker. If you get that response, then the left speaker is the problem. So i went ahead and opened up the speaker. Do this by taking off the fabric cover. There are those little hose plugs you need to take off with a philips head, just wiggle them out. Unscrew the 4 screws. Use a blow dryer around the edges/sides of the face of the speaker to loosen the hot glue holding the cover together. Once the speaker is warm, try prying off the cover. You can maybe use a flat head screw driver to do so but with gentleness or else you'll scratch up the speaker. So once you have that done, look at the terminal(wires that are soddered to the speaker, to check if connected to speaker. if they are not connected, then you would have to soddered them. If everything is intact, then try moving the little plastic piece connected to the speaker, opposite end of that is the possittive and negative wires connected to the cone. I scrapted/moved around the wires being careful not to puncture the cone with the screw driver to check to see if they were making contact with the terminal. I then connected the plug into the amp and fortunately i could hear the speaker once again. I hope this made sense and worked for you. I was glad this worked cuz i truly love the sound of Z-2300 system for the THX certified sound.Sure glad i didn't have to buy another set.

The fix is don't monkey around. Simply reverse the cable leads from computer to the box.
