22-boogie Posted September 7, 2009 Share Posted September 7, 2009 what tweeter problems could exist that would make diaphram replacement needed besides no sound at all? one of my k77m's does'nt sound as clear as the other. i'm on a budget or i'd just replace them, but i don't know if thats the problem.i'm listening to connick jr. right now and its noticeable ,like he needs to clear his throat.lol ya know?best way that i can describe it. thanks all Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted September 7, 2009 Moderators Share Posted September 7, 2009 I would guess not a tweeter at all, probably a midrange, the voice would be more in the midrange. Check wire connections at the driver make sure your getting a good connection. Others will be along with other advice. Quote Link to comment Share on other sites More sharing options...
JohnA Posted September 7, 2009 Share Posted September 7, 2009 Excessive heat from too much power can soften the glue holding the voice coil together. The shifted wire filaments can touch the magnet and buzz. It can happen to any driver. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted September 8, 2009 Share Posted September 8, 2009 As dtel and John said. Also swap the speaker wires and see if the "fuzzy" follows the wire; that would mean connections, amp issues, etc. Likely as not it will be a diaphragm issue if all other things are ok. If it's a diaphragm issue, contact BEC regarding a replacement pair, etc. Quote Link to comment Share on other sites More sharing options...

22-boogie Posted September 8, 2009 Author Share Posted September 8, 2009 WELL DTEL, BINGO! MID HORN IS THE CULPPRET! I Stuffed a sock in both tweets and took piece of cardboard and put it in front of the mid horn, angled it up towards me and i could hear the raspy sound of the voices!The other was clear as a bell. Nickel Creek was a great test cd,... now what?THANKS MUCH Quote Link to comment Share on other sites More sharing options...
oldtimer Posted September 8, 2009 Share Posted September 8, 2009 Check the physical connection for that horn. Clean the connection up and refit. Check both ends of this connection. Quote Link to comment Share on other sites More sharing options...
