ousig Posted December 29, 2011 Share Posted December 29, 2011 when running the audio setup on my Denon it stated that the fronts had a polarity issue. Years back I did take all of the drivers out to fix the back panel vibrations and add some foam. I thought I marked the + and - but possibly I missed something. They sound great to me but not as good to the mic on my Denon. I know you can use a AA battery to confirm the woofers + and - inputs but how about the horns? If I remember correctly they were not marked + or - on the back or if they were I didnt notice Quote Link to comment Share on other sites More sharing options...
djk Posted December 29, 2011 Share Posted December 29, 2011 Placing the speakers face-to-face and driving them (in mono) out-of-phase with each other should give an almost complete cancellation of sound. There should be a spot of paint near the positive terminals on all the drivers. http://forums.klipsch.com/forums/storage/6/331812/klipsch_klf20.pdf Quote Link to comment Share on other sites More sharing options...
ousig Posted December 30, 2011 Author Share Posted December 30, 2011 pretty sure I would have noticed the spot of paint (red or black) if there was one but that was years ago when I was in there. I will check them out this weekend is there any real benefit to replace the internal wiring with some newer stuff? if I remember correctly it looked like small 18 guage stuff Quote Link to comment Share on other sites More sharing options...
djk Posted December 30, 2011 Share Posted December 30, 2011 "is there any real benefit to replace the internal wiring with some newer stuff? " No. I solder them instead. BEC likes me suggesting this as most people can't solder and ruin the diaphragms (at which point they buy new ones from him) . Try cleaning the terminals and squeezing them a bit tighter before pushing them back on. Quote Link to comment Share on other sites More sharing options...
WMcD Posted December 30, 2011 Share Posted December 30, 2011 I think something like this was submitted to the forum years ago. Someone suggested the software may have been detecting the time offset of horns. It was either myself or maybe I agreed. Looking around tonight I found http://ask.audyssey.com/entries/215531-phase-error If reflections can cause as false report, I'd think that horn distance offsets can too. One problem is that we don't know how the software goes about making the analysis. Is it looking at different frequency bands where a woofer and mid and tweeter? Reading the article, it seems that the report does not necessarily indicate a hardware issue of miswiring. WMcD Quote Link to comment Share on other sites More sharing options...
