Yo Shabbadoo, I doubt that you can find a replacement for the EMIT tweeter that will sound half as good. They really are superior to most of the dome tweeters out there. That EMIT tweeter is just complaining about the cheap capacitor Infinity used in the crossover. Try bypassing the last cap (closest to the tweeter) in the crossover with a Crescendo cap of a .1 mf value ($7.45 ea.). Solder it in parallel with the existing cap. Or if you feel flush replace it with the same value in a cascade bypass arrangement. Read all about it at: http://www.northcreekmusic.com/Bypassing.html. By all means discuss the idea with George at North Creek before you try inserting resistors in series with the EMITs. The other thing that will help is if you treat the room with acoustic foam treatments to minimize early reflections off of the side walls, front and back walls and ESPECIALLY THE UPPER CORNERS.
Replacing my tweeters a good idea?
I have a pair of infinity Delta 70 loudspeakers. They have 2x8" 1 6" 1 4" and a metal tweeter. They image superbly, and set a good soundstage. People think infinity are bad, but they are great in my ears, apart from the metal dome tweeter. It gets a bit harsh on some recordings. Is it possible that i could replace the tweeters with something else, say dynaudio tweeters? would it be worht the trouble? I am not getting new speakers.. so dont bother trying to say that. :P thanks
