Hi there,
as it can be read in another thread bl4000 and bl6002 are getting phased out. As I plan to mount my existing 4000s on floor stands in the near future I headed over to german dealer Karpa & Mรผller to look for the current price. By chance I stumbled upon this:

The rumours about a Bose-like actice subwoofer / passive satellite system seem to be true. The text says it's a 4.1 system together with a b&o tv and a 5.1 system together with an av reciever of a third party manufacturer.
