New Tweeters: In or Out of Phase?


I fried a tweeter in a KEF 104.2 speaker and replaced it with a VIFA unit that has .5db higher sensitivity than the stock unit. The VIFA replacement does not indicate + - leads. Does anyone know how do I tell them apart and what are the sonic effects of incorrect wiring? The new tweeters are a great improvement over the orignal 1990 tweeters but are a little bright. I hope this reduces after burn in or is it that they're out of phase? Should I have gone with Morels whose sensitivty is rated at 2.5db less than the Vifa, but might have better matched the 2 midrange elements (from 1990) that might have lost sensitivity since their manufacture in 1990.
Thanks for any responses.

Don't be afraid to put a resistor in series with the tweeter. The crossover probably already has such a resistor (called the "tweeter padding resistor). Just increase its value until you like the sound.
