Someone was kind enough to point out this tweeter to me the other day:Vifa 1" Textile Dome Autosound tweeters. Fs of 1700hz I believe, 30rms, 6ohm (not need for attenuation), and mine were around $60 shipped with angle mounts (have to order separate).

That's what I use. Recommended by Adire Audio to match with Extremis's for in car...on a reasonable budget.
Just a hunch but the vifa prolly sound a load better //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif -- thn again I don't trust any hard domes that I don't know all about and I know next to nothing about those RF tweeters... At that price though they likely aren't bad (considering) //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif -- but the ones mentioned before are -- well better in all likelyhood...That's tempting, but how do they sound? I don't know much about RF tweeters.
