after listening to the "RAAL" tweeter, also known as the worlds best ribbon tweeter, in my new speakers, i came to some conclusions. this tweeters weak point is that it cannot reproduce the highest register, or the highest treble sounds. its strong point on the other hand, is its ability to accurately reproduce the sounds of the musical instruments. (in the part of the spectrum it DOES reproduce). it has a very natural sound. it doesnt color the music at all. it is very true to life or lifelike in its nature. smooth too. hope this helps anybody who is considering putting this tweeter in a pair of speakers. i can live with it in the meantime until my next pair of speakers 8 years from now because i like its natural sound so much. i hate to admit this, but i run some EQ through it to bring it up to standards. so in a nutshell, if you're a freak for high end or just like the whole spectrum to be represented , you're not gonna like this tweeter. by the way, has anybody else heard this tweeter and what are your thoughts about it.
