We use the most advanced, computer-based Klippel and MLSSA systems in our design and manufacturing process, ensuring that our transducers provide optimal performance within their specified application. We custom-design and build our transducers from scratch; winding the voice coils, processing the paper pulp into cones-and even machining the backplates. This enables us to control the quality, and frankly, to make better components. Take Control The B1500D-PRO and B1800D-PRO feature balanced XLR inputs and outputs, as well as balanced XLR THRU jacks for connecting additional enclosures. A BOOST FREQUENCY knob targets a boost frequency between 45 Hz and 90 Hz. Flick the BOOST switch to give your selected frequency a +6 dB boost. These subs also feature a HIGH CUT dial to control the upper corner frequency for the subwoofer's amplifier. The HIGH-CUT dial affects only the signals directed to the subwoofer. The Output A and B sockets have a fixed 100 Hz low-cut filter to facilitate connecting full-range active loudspeakers. A LEVEL knob controls the input gain, and the PHASE switch reverses output phase to compensate for frequency cancellation between the subwoofer and satellite speakers. LEDs show operational status at a glance, including power, signal present and input overloads. Which Speaker Do I Need? As you have probably noticed, we make these subwoofers in two different woofer sizes. Which one is right for you? An 18" woofer has 44% more surface area with which to move air than a 15". If you're engineering sound for a small jazz combo in a small club, the B1500D-PRO might be all the speaker you need. If you need to provide pounding techno sounds to a standing room only nightclub, the B1800D-PRO might be the better choice.
