I think that it's time to cut your losses and part ways with these speakers. Others may love them, but that doesn't mean you have to. I know that it's happened to me several times. Save yourself further aggravation and get back to enjoying music.

Agree with Roxy54. If an equalizer won't get you want you want, cables surely won't. If your dealer suggests putting tissue paper over the tweeters to tame them, you know you're in trouble.
