Deang Posted April 23, 2004 Share Posted April 23, 2004 If you are sure you don't have any loose strands touching each other at the receiver's binding posts, then yes -- it probably is something inside the speaker. Probably just a loose or broken connection, with the wire grounding against something. Open her up and take a peek. Quote Link to comment Share on other sites More sharing options...
bryan750 Posted April 23, 2004 Author Share Posted April 23, 2004 I have opened it up but found no loose connections any ideas? Quote Link to comment Share on other sites More sharing options...
3dzapper Posted April 23, 2004 Share Posted April 23, 2004 Make sure it is the speaker. Swap the L & R speakers and make sure the problem follows. If it does, unscrew the back and make sure nothing came loose during shipment. No change? Unhook the drivers one at a time from the X-over starting with the tweeter. Leaving them disconnected as you go to keep from overloading the tweeter and squaker. Then report back your results. Rick Quote Link to comment Share on other sites More sharing options...
djk Posted April 23, 2004 Share Posted April 23, 2004 If you unhook the woofer in a Heresy II and play it, the amp will fry. Quote Link to comment Share on other sites More sharing options...

3dzapper Posted April 23, 2004 Share Posted April 23, 2004 byran, The most likely cause of your problem is a shorted woofer voice coil. The best way to trouble shoot the x-over is to swap one for the other unless you have an LC meter and can measure the caps. What is the DC resistance of the K-22s voice coil? When you gently push in on the cone do you hear or feel any grit? Rick Quote Link to comment Share on other sites More sharing options...
bryan750 Posted April 23, 2004 Author Share Posted April 23, 2004 I will check this also, thanks any idea on the price of a new one? Quote Link to comment Share on other sites More sharing options...
WMcD Posted April 23, 2004 Share Posted April 23, 2004 I'm unsure. Is it always one which kicks off the amp circuit. Question. If you switch them, is it always that one. Question. Does that one sound bad. Question. If it sounds okay before the cut out, there may be no flaw in the speaker. I suspect that the amp does not like the low impedance of either Heresy. My amp does not cut off. It is too primitive. However, I have make up an autotransformer from Radio Shack 70 volt line transformer to reduce the load on the amp. I don't know if you want to try this sort of thing but I'd be happy to loan my set up (wired with banana plugs) to you so you can experiment.

bryan750 Posted April 23, 2004 Author Share Posted April 23, 2004 Only one causes shut down and I get very little sound out of it before shut down about 2 secs. Quote Link to comment Share on other sites More sharing options...
Deang Posted April 24, 2004 Share Posted April 24, 2004 I received you private message, and have been following the thread. I'm still curious if you switched the speakers around, and whether the problem followed the speaker, or stayed on the same channel. You might also try hooking up another spare set of speakers if you have them -- just to see how the receiver behaves. To rule out whether or not the voicecoil in the woofer is shorted, remove the driver, use a AA battery, and put the driver leads on each end of the battery. If the driver is O.K., it will respond to the voltage of the battery. If the coil is shorted, it won't do anything. If the driver is cooked, a replacement can be purchased from Klipsch.
