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 our amps don’t need massive heat sinks, and that means we can make them lighter. Our no-compromise design means the B1500D-PRO and B1800D-PRO will deliver full power with incredible fidelity all night long, without the need for lengthy rest cycles.
When used in conjunction with switching-mode power supplies, which don’t require huge and heavy transformers, our Class-D amplifiers provide tremendous dynamic punch and superior fidelity. The resulting speaker systems are much lighter, making them easy to transport and set up.
Custom-Designed Transducers
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.
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 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, we make these subwoofers 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.
Value
Plenty of power, light weight, amazing sound, tough durability and affordability— with the B1500D-PRO and B1800D-PRO, you get it all. Check out these high-tech heavy hitters at your nearest BEHRINGER dealer and let them redefine your low end.
