Rocket is a brand of Onix Audio, a 20 year old British hi-fi manufacturer. Onix is currenty owned by a partnership between Mark Schifter and a Chinese entity. Onix owns a factory in China where Onix, Rocket and many other speakers are made under Mark’s personal supervision. Reportedly, Mark spends about nine months a year in China and is very involved with all aspects of manufacturing. This is a considerably different setup from the current trend, of designing a product in North America or Europe and outsourcing production to a third-party in China. Mark actually goes to China to oversee manufacturing and design aspects of the product.
