I have just upgraded my crossovers tweeter capacitors in my RT 12's and I now have a sibilance issue which is driving me mad.I used a Dayton 200v 10uf 1% Audio capacitor with a .01 400v bypass film foil capacitor.I used the same values as the originals.The added bypass was suppose to improve the top end.
I have installed all new drivers.
The tweeters are SL5001's but I also tried SL6001's trilamanites but still have the problem.I removed the bypass capacitor and still have the horrible ssss's in voices.Is it the tweeters Dayton capacitor the tweeters thenselves or something else.Both speakers have the problem.When I change over to my other speakers no problem so its not my reciever amp, CD player or room accoustics.Both speakers have installed the original sponge packing in the enclosures.No change to the internals or drivers all stock.
I dont know if these RT12's had an sibilance issue from new as all the drivers and crossovers were blown before I started the rebuild.Both power resistors were blown.I replaced the blown resistors with the original values same type.Figured I would up grade the tweeter capacitors to something better.
I going to remove the new Dayton Audio Capacitors and install the old Polk capacitors and see if that solves the problem.Anyone had this issue.
