ahoj,
nemate nekdo z vas zkusenosti s temito keramickymi krasavci? na foru www.diymobileaudio.com jsou z nich uplne odvaření:
[ Link ] The ringer for us was the new ADI Ceramic dome tweeters. The moment I hit play, even though I was 180 degrees off axis (directly behind them), I already liked what I was hearing. As I joined the guys in the middle of the sound stage I was very much impressed. These tweeters were very detailed but not harsh in the least bit. They had that top end “sparkle” that we all crave so much. The chimes at the beginning of Sierra Highways were almost magical. And I mean magical to the point I half expected fairy dust to waft out of their little white ceramic domes. These tweeters were like a great cake. The substance was defined and the icing on the cake, the top end, was sweet but not overbearing. The off axis response was very good on these. One thing I’d like to note was that the lens that covers the tweeters seemed to affect the off axis response. With the lens placed vertically the horizontal dispersion was significantly increased. This could be used as an advantage in a car where on axis placement isn’t always possible. After the honeymoon period was over we decided to see how flexible it was with a different crossover setting. We brought it all the way down to 2k at a 12db slope with the mids at 1.6k with a 12db slope. The tweeter did fine playing down that low with respect to the lower end of the frequency spectrum. However, Brian and I both thought that the top end suffered a little bit when we brought down the crossover. Even with the crossover lowered we thought it still sounded very nice. I think the top end could be brought back with a little EQ help. The size of this tweeter also made it a good candidate for the car. The flange is a medium sized but the motor structure/rear chamber wasn’t as big as I had imagined (especially since it’s XBL). I will likely be ordering a set of these.
