50" Midrange Planars?

[amirmk]

Take a look at the genesis 201, they use a 54" ribbon midrange, and their sound is outstanding, my question is, are they the only company to use such speakers, or are they avilable from other companies? Can I purchase a pair?

I believe that Genesis uses drivers from Bohlender-Graebener,
or at least that's what I read somewhere.

Parts Express is the "exclusive" seller of raw B-G drivers

I believe the Genesis ribbons are true ribbons... meaning non planar

also I don't think their as inefficent as those BG's

Neither the Genesis mids OR tweeters are true ribbons. They are both forms of magnetic planars. Heard then all and talked to Arnie Nudell, Genesis' designer, on multiple occasions. The drivers were indeed sourced from B/G at first, buy I'm not sure as of now. Probably still are....

Here are some from the ProAudio sector. I once asked, I believe it was about 1000 Euro per piece. This company also manufactures high-power ESL-Panels (Novason).

One Genesis article mentioned that they use a custom design planar ribbon from Bohlender-Graebener with a thinner film and several runs of aluminum connector, of which only the center track was used for the tweeter function. The article said this increased the frequency response beyond 20Khz, where the current standard B-G planar seems to droop around 16Khz.

Probably the most interesting manufacturer of magnetostatic speakers is this:

Unfortunately they don`t sell drivers, just large scale systems.

el' Ol,
I have a crazy idea : why not to purchase the most little system and
disassemble 32 pairs of these planars?
A group-buy of 32 mans........
Maybe too much euros? I have a bad presentiment.........

Really funny! I had the same idea when I discovered the website.

But I guess we`ll have to buy a subwoofer array, too. Xmax of the system is low, I`ll ask the company what xmax the woofers have and some planar expert here should be able to calculate whether one woofer is enough in an open baffle with side walls.

this thread needs a bump.
(looking for a big and efficient true ribbon)

Res Audio from Italy had a long ribbon, I think it was about 110-120cm long and a neodymium version of it coming up. Seemed really interesting. Wonder what's happened with this company?

Hello,
Crevasse could be an option. But as I heard from the builder himself two years ago, it's not sure that they will be built in future: "In Finland we've sold some, but not too many as to make a living."

Very nice speakers, i particularly like the dfipole bass (eheh).
But "89db" and "very efficient" in the same page is a nonsense.
Pity.
