The ones I've been looking at are made by JW Speaker in the USA. The model number is 8900.

They are available in ECE approval and left hand traffic configuration which is nice.
They are like $550 each though. They seem quite impressive, just not many of people using them due to the high price I think.
Wow Dude.... Those look pretty wild........
