I have a pair of Sequerra Ribbon tweeters for sale. I bought these from the audio shop I worked at in NY 20 yrs ago but the project never went anywhere.
These were apparently used in one of the Sequerra ribbon systems but I do not have any other details except that they are supposed to reach 40k.
They have the matching laminated core transformers that are obviously very over specd. Also have a spare set of ribbons.
Not sure of the current value however I am open to offers.

These look like the Sequerra T-9 ribbon tweaters to me. I own a pair, and just recently sold another pair that I had in use with Sequerra's midrange (Met-7) and subwoofers (Met-8W). His higher priced T-1 would have had a rounded magnet instead of the square one shown. Attached is a descrition of the T-9 speakers.
The t9 is about half as deep as these BTW. These have a much larger magnet.
I have the T1 alnico also and will take a picture of them side-by-side.

BTW here is a t9 for reference. it is much smaller than this one I have, about half as deep and front/back ribbons. Also the transformer is way ,way smaller.
Definitely NOT a T9

Hi there,
Sorry, just found this thread. I have a pair of Pyramid T9 Ribbon Speakers and am looking for replacement ribbons for them. Does anyone have some that you are willing to sell? Or does anyone know where I can buy some, now that Richard Sequerra has passed away and his website has been taken down?
Many thanks!

Hi, I have a pair of metranome 3s, they have these tweeters and if anyone has the specs on any of the parts of the met 3s I'd be very appreciative thank you.
So, they are out of a pair of dick sequerras met 3s I think,

I made some that worked very well from film/foil capacitors that I unwound. I bought a tool to corrugate the foil on Etsy.
Sweet, I am still looking for decent ribon material, I have a few capacitors, I may try that. I just did my ribbons yesterday outa some tinfoil, bc that's what I had.
Thank you for the directions on how to procure these items

The original ribbons appear to be aluminum foil? McMaster-Carr has a huge range of thicknesses https://www.mcmaster.com/ .
