Speakers suggestion that can be driven hard


I have a pair of B&W DM640's. Sound real nice but i have to be real careful with the volume as the tweeter is prone to blowing up. I want to get another set of speakers that I don't have to worry so much about that. i can spend $2000 used. Suggestions?

I have been reading some threads and some people that have older speakers with ferrofluid say it dries out. Maybe that is it? Some songs the tweeter is very clear and on others there is a slight static sound.
The right sized newer OHM Walshes that you can find to fit your room size and the juiciest good amp you can find to throw at them. A clear cut slam dunk for me for this application. You;d be hard pressed to do better at any price. Plus, the room filling omni presentation will not drive you out of the room as the volume goes up.
I had a friend in Minnesota that drove his Snell c5's hard and they always performed for him;at this time his amps were the first run of adcom 555's and then mccormack dna-1 monoblocks.
