Its the polykevlar. thats the series of mids i was going to purchase. they have the yellow kevlar cone instead of the grayish in the utopia line. your utopia sub looks awesome, i love the separate magnets and the chrome front and rear plates. they just look so impressive, i guess they had better for the price you pay for them

. I agree, the tweeters are a little bright, I believe the xovers have a -3db and -6db cut for the tweeters. I cant remember though.
good luck with your install, show me pix for sure...
on a side note, can you take a look at my post in the 5ers column, im not familiar with them. thanx
