D2905/9900 vs. D2904/7000

Which is better? is it the 7000, then is it worth the extra money?

I've heard both in very different setups, and liked them both, alot! But the 7000 is significantly more expensive, so I was wondering if it'd be worth the extra money.

I had 9900 in my loudspeaker. It sounds very good. I auditioned 7000 and it sound a lot better, more details and clearer topend. I just had my speakers re-constructed now using 7100, silk-dome version of 7000. It is significantly better than 9900, but can't go as far as 7000. However, my friends feel 7000's off-axis response isn't as good as of soft-dome tweeters.

My 2 cents.

D2904/710000 seems interesting, but note that it has 4 ohm impedance, compared to the D2905-990000' - 6 ohm.
The other driver, I guess you meant the R2904/700000, -the ring-radiator;
-I have heard it in a very good (and expensive) speaker, and I have heard others mention that it needs a good filter, and much experimenting to make it sound good.
