Any 1 Know about the RX speakers?

a long time ago I saw a rx 7 with a speaker that looks like a rotory symbol .
He gave me a web page and I forgot it . I know they had some bang for a buck.

You guys know what I am talking about ?

 

Like a triangle shaped speaker or sub or something like that? Sounds neat but no i never heard of it.

 

found them what do you think? i was thinking of puting on in the removeable panle in the back seat
