richie1575 Posted September 10, 2008 Share Posted September 10, 2008 Hi All! I have a problem with an EV RX212. There's a strange rattle!. It sounds like this originates from the tweeter, but I'd guestimate the frequency to be around 400Hz I've not had the opportunity to test it since, but I'm wondering how to go about sorting it out! I'm thinking about using a function generator (at low level) and "sweeping" the cabinet to replicate the problem. Sounds easy enough in theory, but is it in practice?Has anyone else had similar issues? I should point out that I've tightened everything up which I can see and all seems well inside the box, and for info, the box was running full range (and carefully) from a Camco Vortex4. Can anyone advise??? Rich Link to comment Share on other sites More sharing options...
fogg Posted September 10, 2008 Share Posted September 10, 2008 Is the HF driver tight on the horn? Link to comment Share on other sites More sharing options...
richie1575 Posted September 11, 2008 Author Share Posted September 11, 2008 Is the HF driver tight on the horn?I removed one of the 12" drivers and checked by reaching in... seemed ok but now I'm wondering! I'll remove the horn and driver tonight and check! Thanks for your reply! Rich Link to comment Share on other sites More sharing options...
aidso Posted September 11, 2008 Share Posted September 11, 2008 If its resonating it could be a few things. Check all the bolts are tight on the drivers and flare. Plus also as said before check the Horn assembly is tight into the flare. Have you noticed any difference in the HF at all? Link to comment Share on other sites More sharing options...
