I asked the folks at Usher if their Be-718 monitor, sold for $2500/pair, would be available in odd-numbered surround configurations like five or seven. "What a great idea!" they enthused archly. Much hard work went into tuning the beryllium-oxide tweeter from which the speaker gets its name. It will ship soon with complementary center and sub. And at 87-88dB sensitivity, the system should run well with a good receiver.
