Company is orientated to Hi-end car audio market, all products and all lines of production are Hand made out of the best possible materials. Their main market is far east, Russia, Japan and lately also US market - there are a few guys in US who are running this awesome speakers - one of them is Mike Young with his super nice VW Bug powered by Milbert amps.
