PreSonus AIR18s 18-Inch 1200W Active Sound-Reinforcement Subwoofer with 2 Ergonomic Handles (Black)
Designed to complement any full-range PA loudspeaker, and a
perfect companion for the PreSonus AIR series, the PreSonus AIR18s Active
Subwoofer delivers a powerful, clear, and accurate low-end punch. With its 18-inch
low-frequency transducer, driven by 1200 watts (peak) of Class D power, it
provides plenty of detailed bottom end, all the way down to 30 Hz.
Design
Despite its power, the AIR18s is portable, compact, and
lightweight, with a rugged, tour-grade birch enclosure. It is easy to transport
and suitable for mobile applications, as well as installs, with integrated
provisions for the included caster kit, ground-stacking provisions, and
ergonomic handles on both sides.
Features
AIR-series subwoofers feature easy-to-use controls and
signal-processing presets. Set them for normal front-of-house use or boost the
low-end with the Mo' Bass preset. Reverse polarity, use the lowpass filter to
set a crossover frequency, adjust the power amp's master output level, and even
turn the grille LED off for installs-all at the touch of a button. A variable
alignment delay properly aligns your three-way system. Most subwoofers are
essentially omnidirectional, which can cause feedback onstage and make
monitoring difficult. Creating a subwoofer array helps keep excess energy off
of the stage and in the audience. AIR-series subwoofers provide the tools you
need to create these arrays with ease. Most importantly, the AIR18s sounds
great, delivering outstanding low-end clarity and natural music reproduction.
Creating Subwoofer Arrays
Two subwoofers in a traditional stereo configuration can
cause a build-up of excess energy onstage. AIR subwoofers’ Cardioid DSP preset
makes it easy to create a cardioid array with a more direct radiation pattern,
keeping energy offstage and in the audience. Or create an end-fire array for
even more off-axis rejection, using the Endfire preset.
AIR18s Inputs,
Outputs, and More
The AIR18s sports two combo XLR and 1/4-inch TRS line-level
inputs with level control, and throughputs are provided to connect full-range
systems or multiple subwoofers in larger systems. You can even defeat the front
power-indicator LED for low-visibility installs or set it to illuminate only
when the protection limiter is engaged.
System Alignment and Crossover Settings
The AIR18s’ variable alignment delay properly aligns your
three-way system, whether the full-range loudspeaker is placed atop the
subwoofer, using the sub pole, or is placed a few feet away. A variable lowpass
filter enables you to dial in the best crossover point. Optimized settings are
provided for AIR-series full-range loudspeakers.
