Let me "agitate waters" here

I own a very compact system from the german brand HK Audio: One 15" Subwoofer (300 W) * two 8" satellites (150 W each). It's a little bit heavy but great for large venues (my number 1 jobs) - the bass is fantastic and the whole system offers top quality sound. I am curious: is this brand sold in the USA or restricted to Europe?
