Thanks Wadia 150, I know the hales vifa tweeters are 4 ohm tweeters but the millenium Seas tweeters which are rated at 6 ohms apparently are still a good match. I am not the only one who has dropped a pair of Seas Millenium tweeters into a pair of T5's. They work nicely. Once again there was nothing wrong with the Hales Vifa tweeters but I changed in an attempt for change.I actually for experimentation sake would love to be able to retry the origional tweeters but mine are long gone.If anyone knows where I could get a opair of Hales tweeters please let me know. I would buy a pair just to try them again.
