Experience with adding super tweeter?

thanks for the input. What happened to the soundstage (size, precision)? 

Soundstage became more expansive and enveloping, in particular with the dipole supertweeter, which was really nice. On the other hand, the precision of the imaging decreased iirc (not 100% sure on this one). There was a pervasive sense of diminished temporal precision, though, what I called transient blurring in the previous post. The bad effects were less significant the higher was the crossover set, so I preferred it at 16 kHz for the most part, but they were still there.

By the way, positioning mattered.

Makes sense, more 'airy', less 'precise'. 

For test purposed (proof of concept), would it be sufficient to get my hands on a 'super tweeter' (ribbon, similar) and make a simple 6 db/oct high path (with various crossover points to play with)? 

I guess it depends on the way your system sounds. Does it lack air?

I have owned the Townshend super tweeters when I owned the Eggelston Works Andra 2 speakers. These speakers had the Esotar tweeters that some raved about, but I thought they lacked the "air". The Townshend's improved the sound immensely.

And if I remember them correctly, I think you can select the crossover and sound level.
