Which Tweeter preferred- dome natural material, Beryllium/Metal or Planar Ribbon? Why?

100db sens in a  tweeter is wayyyyy too high for my preferences. 

91-93 is my ideal. 94 ok perhaps. But not 95db. 

I can not work in dual tweeters with a  sens higher than 94db,,so actually , back to my 93 db as limit sens. 

Below 91 db is too low.

91,92,93

The price is totally pointless here.

I just wished to suggest that there are various specifications, that could explain the contradictory feedbacks.

I modified my AMTs to take the peak out of the high end (~10kHz) using a diffraction lens I designed/developed, and to boost the lower end by extending the flair.

I also remove the back wave because I don’t want the reflections, which can be unpredictible.

I also designed and made the stands out of 3/8" smoked acrylic cut on the laser table.  I also have a pair in clear if anyone is interested in them.

Back to tweeters….

Best I’ve heard so far are the ribbons on the Quad z-2. 

As described in Stereophile … as it goes in the wrriteup goes for the smaller lower quad speakers  

Have heard the quad S-2 that have a smaller version … “were incandescent in”there highs  I think the z-2 exceed the S-2 and should as the tweeter is twice the size.

last favorite was the titanium domes on psb speakers  

magenapan quasi ribbon was not as transparent but haven’t yet heard the new revamped Maggie’s  

look forward to my next steps up to beryllium and diamond done  

dont like the myriad of soft tweeters speakers (of differing materials) I’ve heard as they dont get brass instruments and cymbals right with the proper metallic clang
