Hey guys, I'm new here! Long time lurker and I could really use some help from the guru's I've been using my old Kenwood km-209 power amp paired with the kc-209 amp controller to drive my vintage KG4's. The kenwood is rated at 150w although the specifications say 155+155 for both channels and says 'Music Power' Is 310w. Here's the specs: http://www.hifiengine.com/manual_library/kenwood/km-209.shtml I ran the volume at about 50% for about 30-35 minutes until I came downstairs to lower the volume for about 30-60 seconds and then powered the system off. When I turned the system off, I heard a pop go through the speakers. It wasn't blaringly loud, but it was loud, and concerned me. I noticed the amp was pretty warm at that time, too. After letting it cool off for about ten minutes I turned the system back on and heard a strange garbled sound coming from the speakers. When I played music through them, the tweeters weren't putting out any sound. I plugged in my EPI's to test, and their tweeters worked, so, I'm pretty sure something happened to my KG4's. Now, I'm a little concerned.. Can't these KG4's handle some juice? I was very skeptical that I might have damaged them with this system. I am also an idiot when it comes to audio equipment so please forgive me, I'm learning. Does anyone find it peculiar that both tweeters would blow exactly at the same time, AFTER I turn the system back on at a low volume? So weird to me. Thank you for your help! Sean
