Kain Posted January 12, 2003 Share Posted January 12, 2003 Lets there are two speakers. On one of the speakers one of the woofer is "bad" or "spoiled" and does not sound right. BUT, could you tell which speaker has the "bad" woofer without listening to either speaker? What if you gently tapped the woofers with your fingers? If you tapped a "good" or "working" woofer, would it sound the same as when you would tap a "bad" woofer? Quote Link to comment Share on other sites More sharing options...
bkrop Posted January 12, 2003 Share Posted January 12, 2003 You could look for rips or tears in the face and cone of the woofer, or tears or breakdown of the flexible material that allows the woofer to move in and out. Quote Link to comment Share on other sites More sharing options...

TheEAR Posted January 12, 2003 Share Posted January 12, 2003 No you dont tap the cones or dustcap.If no visible damage is present thengently push the woofer membrane in,near the dustcap.Press on both sides not to damage the cone.If you hear a scraping noise the woofer is shot.The membrane should move in and out with no friction from the VC on the magnetic gap.Remember the metalic Klipsch cones are not as rugged as polyprop,if you deform the cone its RIP time.Polyprop cones are more rugged and can take alot of abuse,the however flex much more then metallic or paper cones,often used in lesser quality drivers. This test is not valid with midranges and tweeters.There you have to listen I destroyed a Klipsch LF10 woofer when running max SPL tests,the woofer VC hit the magnetic structure and a loud "CLUNK" was heard.After the woofer cone when pushed in in the center made a craping noise OUCH.Lemon woofer or just faulty design.

cluless Posted January 12, 2003 Share Posted January 12, 2003 Hmmm...I would strongly suggest performing the following... While holding a pair of 5 volt batteries between your rear molars and your favorite remote control between your teeth. Raise the volume on your receiver until the cartons start to vibrate...at that point if one of the woofers is outta wack..you'll know it..
