SilverSport Posted December 31, 2007 Share Posted December 31, 2007 ...I have Klipsch Quartets (smaller brother to the Forte' IIs/Chorus IIs) and am wondering when the rear mounted passive radiator goes...what goes bad on it???...does it require any maintenance ever???...with Heresys...new crossovers and good care might be the only thing required to keep them running indefinitely but what of the Quart/Forte/Chorus family???

carbon summit Posted November 22, 2008 Share Posted November 22, 2008 The passive radiator on one of my KG-3.2s has kind of a buzz to it sometimes and when you lightly push in on it it has a rough feel. The other has no buzz and feels smooth. Any ideas whats wrong? Quote Link to comment Share on other sites More sharing options...
oldtimer Posted November 24, 2008 Share Posted November 24, 2008 Check the integrity of the passive for anything loose that might buzz. Something may be unglued. If nothing seems to be wrong you might take it off to see if something on the inside is touching. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted November 25, 2008 Share Posted November 25, 2008 Unscrew it, remove it and make sure that the counterweight area on the back is secure, nothing loose, etc. Check the gasket and when re-installing it, make sure the screws are "cross torqued" and even. That should solve the problem. Quote Link to comment Share on other sites More sharing options...

The other has no buzz and feels smooth. Any ideas whats wrong? You sure you're pushing on the passive radiator? What you describe is very common when you've got a mis-aligned voice coil, but passive radiators don't have voice coils... One thing you might consider doing is rotating your speaker 180 degrees. Over very long periods of time, you're going to get sagging in the surround and spiders. Rotating the speaker starts the sag in the opposite direction. I bring this up because I've had speakers sag to the point of allowing the voice coil to rub. Rotating the speaker was a 2 minute fix for alleviating the problem (for another dozen years until it sags too far again). The same logic applies to passive radiators though...the sag can cause it to rock sideways instead of moving in and out like a perfect piston - ultimately this results in distortion (and not the good kind either).

Groomlakearea51 Posted November 26, 2008 Share Posted November 26, 2008 And I thought I was the only one that rotated woofers..... Or is that a "Saggy Dog" story?[] Quote Link to comment Share on other sites More sharing options...
