Berylium dome tweeter

tinitus · 10th August 2008, 11:41 PM

Now who would have thought that, a new Hivi berylium dome tweeter, with short rings and neo magnet, and no chassis screws close to diaphragm and nice rounded edge, thats very good...but the protection grille, well nothings perfect

This good looking fellow almost makes me wanna skip my horn project

Looks like a TB 25-1743S to me.

Man, sorry

I wrote Hivi and it should be Tangband, thanks fore correcting

Wonder how much it will cost, now that some claim berylium to be very expencive

TB partsexpress
my local dealer wants to have 83€, not that bad i think.
do you believe it sounds nearly similar to a focal TBe? FS is really low.

That looks beautiful.

I know nothing about speaker building and normally hang out on the class d or pass labs forums, but this makes me want learn. Seems like this would be an ideal place to start for a high quality 2 way design.

It's the wrong color for beryllium. S/B a dark grey/blue color. Must be over-plated with some other material.

the only reason i see in covering beryllium is safety.
hopefuly not at the cost of sound quality

Hope Usher starts selling their berylium tweeter and mid.

Data sheet says 'ceramic' dome - guess this is beryllium oxide?
Early rolloff too.

I think you may be on to something here...

Besides, I hope I'm wrong, but $90 for beryllium seems low to me.
