Beryllium speaker question

I've been trying to find a list online of what Yamaha NS speakers had beryllium tweeters/ mids in them.

Any expertise you guys could lend would be much appreciated.

Ty yea those are the most popular. What got me interested in knowing is I recently aquired a pair of NS-25t's from a garage sale and they have a beryllium tweeter in them.

so I'll add those and the other obvious one :)

NS-10M
NS-25T

I'll make a master list in the OP.

Sorry, the NS-10M has a cloth dome. I think the NS-25T is Ti but could be cloth as well.
 
Nobody mentioned the Be Masterpiece? Yamaha's toxic Magnum Opus? The GF-1

thanks for the fx recomendations! Anyone know if there are any other speakers in the NS-20's through NS-600's that have beryllium?
 
NS-10 has a Be tweeter. I'll try to remember to post the link to the Yamaha speaker history page once I'm on my computer.

The NS-10 JA0518/A tweeter is absolutely a fabric dome tweeter. I've had countless JA0518's apart and they are not metal domes.

From Yamaha's data manual

The JA0518A tweeter is a laminated soft dome topped by two different dampening resins ; the three layers are put together through special manufacturing allowing utter precision in alignement. Weighing a tiny 0,6g (edges + dome !), response is swift, precise and controlled.

You are correct about the NS-10.

Did post the the listing of Yamaha speakers on the bottom of page 1 of this thread. Click on each speaker for details.
 
Ns25t

The NS25T beryllium is some type of 80% scale model of the 1000 tweeter I believe, the face plate while it looks awful lot like aluminum, its actually plastic ... yes the thing has the frosted look and looks just like aluminum, but is plastic. The tweeter part number is ja-0549.
The cabinet has a 8 inch woofer made of a grey paper like cone and the left and right speakers are mirror images of each other, they're not identical, mirror imaged. Its meant to go horizontal, like the ns10 ...
Anyway it sounds very good especially mid and high.
Cool.
