Small but high quality tweeters?

[Tenson]

Hi,

I am looking for a really high quality tweeter that is also small, for a 7KHz Xover (so extends to 3KHz, but best quality from 7KHz up).

I want it small so that I can place it close to the midrange driver and cross so high.

The one I can think of is the Vifa XT25SC50 - the little neo version of the XT25. The problem is that it is not really as high quality as I would like (seems to have some ringing in the CSD) and from what I understand these tweeters have a rather narrow dispersion. I like wide dispersion

Tangband seem to make a number of neo tweeters, but I have only seen measurements for the ones on Zaphs site. Anyone know if one of the others happens to be a bit special?

What else is there? I am looking for something with rather exceptional performance.

Thanks!

Zaph tested the d26nc-55-06e with very good results. Quite cheap if you can find it (I think it is out of production)

Vifa D26NC55 ($26) - Very smooth response with mild tilt down of a couple dB over it's range. Near perfect CSD without no high frequency garbage. *Very* low HD above 2.5kHz with a mild 3rd order peak at 1.6kHz. Almost a complete lack of tall order HD products. Well built small flange neo with heat sink and excellent internal construction.

Thanks that one does look rather nice. The fact it is out of production is a bit of a PITA though! Also, the 3rd order HD is a little higher than I would ideally like, but it would suffice I guess.

I bought some of those Vifas from Madisound recently, they may still have stock. I doubt you will find any real data but some of the high end car audio tweeters are very nice, Res Audio Detectors, Morel Piccolo. or could you cut down/make a new faceplate for a known good tweeter, something like the Scanspeak with phaseplug (number eludes me) Genesis use that model (or a variant of) in their high end absolute speakers.
