Used Korean Speakers


Has anybody heard these famous Korean speakers? I don't know what kind of amps you would need, and the wife acceptance factor has to be very low, but I'm intrigued.

The driver array is mounted in some kind of horn structure, like a Tractrix, and it reminds me of old cinema setups. Then multiple units are spread out over hundreds of feet, maybe miles.

Are the drivers 15"? Full range or coaxial? I can't tell. There's very little information on them. If they're dismantling and selling them off, they might be worth a listen.
Guys, guys, I know this!  That's either the first prototype of the 901, or the latest model.
For some reason, I am doubting that you actually heard these speakers. Unless maybe you are Dennis Rodman.
