Anything else... They look like shit and are impossible to mount. They are just too big. And you can't point them at your head or your head will explode.
What model number or type are these eminence tweets?
Really, the piezo horns I have (standard 3" horns really) are quite respectable tweeters, anyone who disses hasn't heard them. IDK what the deal is but they blend well and overall are pleasing and mellow but can get **** loud but sometimes i can detect honking.
I have no crossovers at all on my tweets or mids, no door deadening and I still get great sound out of them with the 7" daytons the headunit, lacking a little midbass cause the doors aren't deadened.
