How long untill I can really Flog them Hard

Ellrotts, that number of big B&Ws a year is a respectable number given the price of those models. It should ensure in the very least a biggger pair or 2 than what one customarily might encounter. There are several other brands that you may want to investgate that are even native to your shores.

I agree with Chayro to some extent, but also have to ask how loud is loud? You can get a Db meter at Radio Shack on the cheap side which will give you a way to measure the strength of the signal at your listening position. At 100Db your getting a pretty loud sound pressure. I bought one out of curiosity you may want to as well.
I don't think there are many speakers made for Audiophiles that are capable of prolonged high spl levels, that is why I agree with Charyo . I have a pair of Klipsch LaScalas (amongst others) that can do that but they are also marketed to clubs and other "pro" venues. If it is much lower you may not really need those speakers, the sound quality is different and may not be to your liking.
