Giant-killer monitor speakers. The BMR wide-frequency driver (that circular thing above the woofer) produces all frequencies above 250 Hz, at which point the woofer takes over extending the response to 40 Hz or so. The lack of a crossover in the midrange provides a level of clarity and cohesiveness typically only heard in large panel speakers. You can read the excellent reviews online. Cosmetic condition is near mint (the right speaker in the 1st pic has a bright spot on the logo but it's only a reflection of the flash). The current Aeromax which replaced this model retails for $600/pair. FREE SHIPPING to the contiguous 48 states (excludes Alaska and Hawaii). No foreign shipping.
