The Q-SUB is a subwoofer that can be used with either the D6 or D12, or with the E-PAC. Its technical specifications are as follows: frequency response of 37 Hz - 120 Hz, maximum sound pressure level of 136 dB, rated power of 1000 W, and peak power of 2000 W.
The Q-SUB is the subwoofer for the d&b Q-Series and can supplement Q1 and Q7 cabinets in flown or ground-stacked combinations. It is an actively driven bass-reflex cabinet with a long-excursion 18-inch driver, a frequency response from 40 Hz to 130 Hz, marine plywood construction, a metal front grill, handles, wheels, and EP5 or optional NL4 connectors.
The manual describes safety precautions, connector wiring and pin assignments, operation with D6, D12, and E-PAC amplifiers, the 100 Hz setting and Cardioid Subwoofer Array (CSA) mode, technical specifications, and use with Q1 and Q7 cabinets.
