I'm adding some tweeters to my system and have a few options...does anyone have thoughts on the following?

Panasonic EAB-ST12 = $60
Kicker R13 = $70
Memphis Audio (not sure of model number) = $80
JL Audio VR075CT = $90

I know that they are all at different price ranges, but does anyone have anyt thoughts or experience with any of the products above?

I know Kicker and JL make great subs, but are their tweeters any good? And the guy at one of the shops said the Panasonic tweeters were pretty good, but I've never heard a Panasonic speaker or tweeter before. I've also never heard a Memphis in person before.
