NotesThe low and middle frequencies are radiated by an 8-inch woofer augmented below 45 Hz by a 10-inch passive radiator. The bass system is based on a fourth-order Butterworth alignment. The woofer response has been designed to roll off naturally above 1,800 Hz, where it crosses over to a single 1-inch-diameter inverted (concave) dome tweeter. No series inductor is used to roll off the woofer's high-frequency output, so its damping is not impaired by the added resistance of a crossover coil. The tweeter, which has a double-layer voice coil in a ferrofluid-filled gap, is designed to withstand very high power levels without damage. Every Genesis tweeter is tested for 2 minutes at 2,000 Hz at a 30-watt input (the company's tests show that it can handle 100 watts at 2,000 Hz for more than a minute). The woofer has rubber impact bumpers to minimize damage from excessive cone excursions.
