Question about JVC HX-D77 Shelf System
Switch it around connect the right side to the left output and connect the left side to teh right input and see if the same speaker isn't pushing air if it still isn't pushing air then you have a few damaged speakers. If it starts to push air on the side that didn't then it could be a dead output.

I have the same stereo system. The JVC HX-D77 has 4 air ducts (GIGA TUBES). The lower two are very active air ducts. The upper two are more passive but they still move air. If only one of the subwoofer air ducts is moving air you may have big problems because one subwoofer channel drives the subwoofer and the woofer above the subwoofer. If it was the left channel air duct that is not working both air ducts on that channel should not work and both air ducts on the right channel should work. If only one side is not working check the wireing make sure that both wire ends are in perfect condition. If they are this may indicate one side of your subwoofer amplifier may be fried. If you actually only have one air duct working that would indicate that you would have three faulty speakers. (Highly unlikely) I would recomend that you unplug your JVC HX-D77, remove both speakers (Main and subwoofer) check all of the wires. If they are fine hook your speakers back up and plug the unit in. If the problem still persists contact JVC.

You should double check the wiring.
