The kid makes a good point in that drivers alone don't make a speaker. I've had the H420, Hll89, the alon alnico and the millenium tweeters (all are SEAS models) all here at one time or another. The millenium is one nice tweeter, I thought of it as organic sounding, it has body. Of the other SEAS tweeters I enjoyed the H1189 next best. The others are aluminum dome and sound a little more brash, I'm thinking you would prefer a soft dome tweeter.
I am now using the Esotar tweeter in the Merlins and I find it to be another sweet sounding tweeter, perhaps a touch lighter and airier than the millenium.
In my opinion the one thing the millenium lacks is perhaps just that touch of lightness and airiness (the SEAS alnico tweeter had both in spades).
Again, perhaps these differences are due in larger measure to the design and implementation of the entire loudspeaker.
