Re: Diamond Tweeter?
All I know is I wish I could afford a couple sets of Sierra Lunas (hopefully that's the name) with that incredible diamond tweeter as an upgrade. I haven't been using headphones as much and these would be the absolute ultimate desktop speaker if paired with a little sub at a desk.
Anyway, these things really are incredible, and yes they're very different beasts compared to the PSB tweeters or many others. It's easy to throw tons of power at a $25 tweeter, but I think everyone here would cringe if one felt even the slightest bit wary of putting dangerous amounts of power on a $5,000 tweeter. This is speaker design only for the pros. You need to know exactly what you're doing as you can't risk making a mistake during testing.
It reminds me of blowing a bunch of speakers I got at goodwill in college trying to make corn starch monsters videos for a physics project. I made mp3's of different frequencies with a tone generator and used my roommates crappy receiver to power the speakers. I blew 4 pairs or so before I got a decent video. I think I was throwing all kinds of crap at those speakers that I shouldn't have been, wondering what was going wrong. I'm not to be trusted with such matters!
