Berhinger's EUROLIVE B1800D-PRO active 1,400 watt subwoofer is destined to become the new standard in low-frequency reproduction. Packed with an incredible array of truly professional features, these brutes provide extreme levels of low-end punch, with the kind of definition and clarity typically reserved for much larger systems. Class-D amplifiers (with switch-mode power supplies) drive the custom-designed low frequency drivers for sonically optimized output. And the best part of all—these new B1800D-PRO provide a much better power-to weight ratio than many competing active subwoofers. Put simply, these cool-running systems are much lighter, making them ultra-easy to transport and set up— and our no-compromise design means you get amazingly-deep, chest pounding bass that will keep the party going all night long. They'll add needed bottom-end to your active full-range speaker system.
What is Class-D Technology?
Instead of operating relatively continuously like Class AB circuits, Class-D amps switch on and off thousands of times per second, delivering power only when needed. In other words, the amplifier is either fully on or fully off , which significantly reduces power losses from the output devices given off as heat. Less heat means these amps don’t need massive heat sinks, and that means Behringer can make them lighter. This no-compromise design means the B1800D-PRO will deliver full power with incredible fidelity all night long, without the need for lengthy rest cycles.
The transducers (woofers and tweeters) are the only part of a sound system you actually hear, so we don’t cut any corners. We custom-design and built our transducers from scratch. Not only do we wind our own voice coils, we process the paper pulp into cones and even machine our own backplates. This enables us to control the quality, and frankly, make better components.
The B1800D-PRO features 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 does not affect the THRU signals, only signals directed to the subwoofer (however, it does affect the signals sent out through the Output sockets of the subwoofer to reach the full-range speakers). 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, these subwoofers come in two different woofer sizes. Which one is right for you? An 18" woofer has 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.
