- 2 x 12" powerful low resonance bandpass subwoofer
- 800 Watts RMS / 129 dB peak SPL / 40 - 140 Hz
- Sub extension for MAUI 44 to double the bass performance (+6 dB)
- Slave preset - follows settings of main subwoofer
- Standalone preset - For use with any other PA speaker
- LECC DSP for constantly adjusted bass response
- Protection circuits for secure, reliable operation
The LD Systems MAUI44SE is a powerful active subwoofer, especially designed for the extension of MAUI44 systems. The compact bandpass design augments the deep bass performance of the system by twice the SPL to (+6 dB) and can be integrated into the system within seconds. Through a slave preset, the MAUI44SE takes over the settings of the system subwoofer, a standalone preset allows it to be used with other satellite speakers.
The housing made of 15 mm multiplex is equipped with two 12" neodymium woofers. The Class D amplifier of the MAUI44SE with highly efficient switching power supply provides a whopping 800 watts RMS; protection circuits against overvoltage, short circuit and overcurrent ensure reliable operation. The frequency response of the subwoofer ranges from 40 to 140 Hz, the maximum sound pressure is 129 dB.
An integrated LECC DSP with 24-bit converters and limiters, EQ, compressor and crossover functions provide an optimal bass reproduction. Furthermore, the MAUI44SE is equipped with controls for the subwoofer level, crossover frequency and phase, LED indicators and a Neutrik PowerCon mains connector. The ergonomic LD Systems Evolutive carrying handles allow for convenient transportation; an optional castor board can securely connect to the subwoofer via butterfly latches.

Features
Lightweight portable powered speakers with legendary QSC amplifier power and reliability
1000 watt continuous Class D power module
Extensive DSP enhances system performance
Attractive and professional appearance
Rugged birch plywood enclosure
Comfortable ergonomic handles
Threaded pole socket with speaker pole included
The KSub is a dual-12" bandpass design, constructed of premium birch and includes high-quality, low-noise casters. The subwoofer features a threaded pole receptacle for a positive, wobble free connection to a threaded speaker pole (included).
Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Euroblock connector. In an installed application, multiple K Series speakers can be "daisy-chained" for total gain control from a single remote pot. Auto-standby mode is engaged after 5 minutes of inactivity.
Extensive DSP
DMT™ (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.
Intrinsic Correction™, first featured in our high-end line-array products maps 65-75 spacially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass target. The result is a speaker that behaves equally well across the entire sound field.
DEEP™ and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.
GuardRail™ protection, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.

| 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. 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 Class-D amps don't need massive heat sinks, and that means we can make them lighter. Plus B1200D's amplifier provides all the dynamic punch and fidelity you'd expect from a much larger, more expensive subwoofer.
Custom-Designed Transducers
The transducers (woofers and tweeters) are the only part of a sound system you actually hear, so we never cut corners, and we never just grab whatever happens to be on the shelf. We custom-design our own so they are the perfect match for both the amplifier and the application. We wind our own voice coils, 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 12" long-excursion, low-frequency transducer was designed specifically for use in the EUROLIVE B1200D.
Take Control
The B1200D features balanced XLR inputs and outputs, as well as balanced XLR Thru jacks for connecting additional enclosures. A Boost Frequency knob lets you boost any frequency between 45 Hz and 90 Hz. Then just flick the Boost switch to give your selected frequency a +10 dB boost. We've also provided a High Cut dial that controls the upper-corner frequency for the internal amplifier without affecting Thru A/B signals. A Level knob controls the input gain, and the Phase switch reverses the 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.
