I don't worry too much about things like this. Unless they start dropping their high end offerings and selling plastic blue tooth keychain speakers at Walmart they will probably be just fine or even better with the infusion of cash.
The best example I can use is Porsche in the 90's. They were purist, only sports cars and only produced in limited quantities. They were also almost bankrupt. They put out the Cayenne and the Boxster, the purists cried and moaned but the company came back in a big way. Now they have a full line of cars, lots of crazy high end offerings due to the money they make on the more pedestrian offerings and are on solid financial ground.
I'd much rather see B&W get their name around and continue selling a full range of speakers rather than going the way of so many high end manufactures i.e. dying.
