As previously stated it was most likely distortion resulting in the blown tweeter rather than too much power into your B&W's... Since you were asking about speaker choice though, Zu Omen's high efficency allow very high sound pressure levels from modest power. If you listen at levels likely to cause the neighbors to complain, consider them or perhaps some of the Klipsch Heritage series speakers if the wide range/no crossover approach is not to you liking. These are well within the budget range you mentioned.
