Ring radiator tweeters - the future?

Bombaywalla, It's not even a question of wheather somebody likes the speaker, its just I don't know how your so off on the tweeters description. I mean, most people consider it one of the warmest, most laid back tweeters. Krell, Audio Physic, Polk Audio LSi...perhaps it wasn't an LSi series I don't know...but it's so far on the other spectrum...I simply don't undertsand the "sharpness" your talking about.

Themadmilkman,
Yes I can see your point, but I also know I have no use for a tweeter at the present time. I hear plenty of tones and overtones without having what some consider tweeters drilling it into my head.;-) I also don't have to worry about hearing the highs before the rest of the frequency. Some have become so accustom to it. They wouldn't know correct timing if it were on their wrist.

I'm willing to bet your vandie's highs start to roll off above 2000hz and continue to roll off to their stated high frequency range cutoff. From the professional reviews describing this speaker "the 1Cs were somewhat hazy and veiled, particularly from the midrange on up". Comments like this leads me to believe the speakers are rolled off quite a bit... Even with the help of a tweeter. So you're not hearing as high as you think you are my friend.

I've had speakers that did the 40Khz thing. Yes they had the WOW factor but also became more irritating to my ears than what it's worth. I've not heard this model of Polks. Maybe it's better than all the other models I've heard. Which were all boom and sizzle..just my honest opinion.

As long as a speaker covers my hearing range . Which is realistically 20hz to 16khz...I'm a happy camper. I have no use for the hash that lies above this point. Whether it comes with a tweeter or not this is the range that is most important too me.

Cheers

Gmood-- y're using a wide-range driver. You have tweeter response anyway.
Out of curiosity, how do you cope with the 4kHz bump in yr response (I'm referring to the "sizzle" you mention)? Note, I'm not knocking yr spkr --just asking.

BTW, the Vifa & Scan rings are not necessarily the problem: their implementation is usually the problem.

Hi Gregm..my speakers uses a Baffle step correction circuit that smooths out the 5khz bump. There's also no shout as with most wide range drivers. Yes I agree ..it's not the tweeters but the way some are used. I really have nothing against a separate tweeter .As long as it has the proper crossover.

Gmood1...Why do tweeters exist? Because drivers with large cones, necessary for LF reproduction, are lousy for HF. "Lousy" means irregular frequency response within the pass band (peaks and dips) and premature roll off, sometimes covered up by a kluge called a whizzer cone, which generates lots of HF sound not necessarily related to the music. (But the ear is fooled). This can be worse than any effect of a crossover. A tweeter, having no requirement for LF response can quite easily be optimized for HF. With proper crossover design, and a tweek or two, use of a tweeter is the best solution for full range sound.

If you are happy with response to 10 KHz or so, then you don't need a tweeter.
