Super Tweeters

[sreten]

Hi,

Personally I'd say the 3/4" dayton with various series caps as a
supertweeter is best used aligned to bounce treble off the sidewalls
and filling in the lack of a typical dome tweeter top end dispersion.

rgds, sreten.

I see one advantage with a tweeter going that high
using a small series inductor you can achieve a slow gradual rolloff, which is nice
much better than abrupt steep shutoff rolloff
earlier gradual rolloff by means of a small inductor also deals with some of the possible noise issues you may have from digital equipment, wireless transmission etc

Or in other words avoid sources with ultrasonic content (especially digital mush) like SACD and non-upsampling CD with no low pass filters

A moderate roll off low pass starting to cut in above 15 kHz is much cheaper than a super tweeter. It does not need to be as steep as the brick wall of early CD players with phase and pre-ringing issues

Supertweeters are still around where cost is no object. 🙂

Spot the supertweeter...

An Audax TW034 34mm tweeter and SEAS 22TFF 22mm supertweeter here. The idea really is to extend the frequency at which dispersion is good. This should make for an airy sound. The big Audax allows you to use a lower crossover point from the woofer too, which loses cone breakup. That's it really. Better I'd say. 😎

Steve, you are very good sales man 😀
