This is the KEF KHT3005 5.1 speaker system. The enclosures are described in one location as being solid aluminum and in another as having silver automotive paint -- whatever... They should make 'em from titanium for the $1500 price though. The shape is seductive and their axles will never need replacing -- so obviously they're cool. They're a bit small for full home theater but probably too much for inside an Airstream. A fun thought anyway. For more info see
