mr.pee1 Posted July 13, 2016 Share Posted July 13, 2016 Got one if the La Scalas put together listening to Roy Buchanan sweet dreams 2 cd set. The k77 is almost non existent, so is the element gone, I will try the other k77 and hear if it makes any differance. Oh I have AL xovers , Dave rest of $ is on the way.

Marvel Posted July 14, 2016 Share Posted July 14, 2016 Do you have a multimeter that you can use to chech the dc resistance (dcr)? You must disconnect it from the crossover to do this. Bruce Quote Link to comment Share on other sites More sharing options...
jason str Posted July 14, 2016 Share Posted July 14, 2016 Could be a set of cheap aftermarket diaphragms installed, the market is flooded with them. Quote Link to comment Share on other sites More sharing options...
mr.pee1 Posted July 14, 2016 Author Share Posted July 14, 2016 I swapped k77s and still nothing out of tweeter. They ohm at 6.7-6.9 . Oh I only have one La Scala hooked up. Quote Link to comment Share on other sites More sharing options...
jason str Posted July 14, 2016 Share Posted July 14, 2016 Make sure all the screws are tight on the crossover. Quote Link to comment Share on other sites More sharing options...
jimjimbo Posted July 14, 2016 Share Posted July 14, 2016 Yep, definitely could be a screw loose.... Quote Link to comment Share on other sites More sharing options...
Marvel Posted July 14, 2016 Share Posted July 14, 2016 Yep, definitely could be a screw loose.... I see what you did there... Quote Link to comment Share on other sites More sharing options...
ricktate Posted July 14, 2016 Share Posted July 14, 2016 If you swapped them,,,seem crossover is at fault i would think or connectins on caps is bad. Quote Link to comment Share on other sites More sharing options...
mr.pee1 Posted July 14, 2016 Author Share Posted July 14, 2016 And then I took one of the tweeters apart and everything was so old it all was stuck together, ruined diaphragm in process . Quote Link to comment Share on other sites More sharing options...
jason str Posted July 14, 2016 Share Posted July 14, 2016 Going to be hard finding good diaphragms, may end up having to buy new tweets. Quote Link to comment Share on other sites More sharing options...
mr.pee1 Posted July 14, 2016 Author Share Posted July 14, 2016 I know I might call Bob see what he has, or go with ebag for not so good diaprahms. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted July 14, 2016 Share Posted July 14, 2016 I know I might call Bob see what he has, or go with ebag for not so good diaprahms. I believe that if they were mine, I'd get some tweeter diaphragms or tweeter assemblies from Bob and listen to them for a while. Quote Link to comment Share on other sites More sharing options...
mr.pee1 Posted July 14, 2016 Author Share Posted July 14, 2016 Can they ohm ok and still be bad? Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted July 14, 2016 Share Posted July 14, 2016 Can they ohm ok and still be bad? The tweeters? I guess it's possible but not probable. Quote Link to comment Share on other sites More sharing options...
