T
he StudioLive 18sAI is the
powered 18" subwoofer in
the StudioLive AI-series loud-
speaker line. It is designed to compli-
ment full-range StudioLive AI-series
speakers while being flexible enough
to work with other powered loud-
speakers.
Interestingly, it incorporates more
digital signal processing than any
competitive full-range speaker on
the market. This allows it to func-
tion as the final component of a true
4-way system when used with Stu-
dioLive AI full-range models.
The StudioLive 18sAI utilizes the
same 2x500-watt bridged power
amplifier distribution that powers
the low-frequency woofer in the Stu-
dioLive 312AI, 328AI, and 315AI. It
also features stereo inputs that, with
analog pass-thru, can be summed
mono.
The 18sAI features two DSP con-
tours optimized for live performance
and enhanced low end. It also oers
three delay presets: 0m for use with
a full-range speaker atop the sub;
1m for use with a full-range speaker
on a separate speaker stand; and 2m
for use with a full-range speaker on
stage.
An optional card provides Dante
networking.
Advanced 24-bit floating-point
digital signal processing.
Like the StudioLive AI-Series
full-range models, the SL18sAI was
tuned by master speaker designer
Dave Gunness using Fulcrum Acous-
tic’s proprietary algorithms.
This results in a truly "smart" sub-
woofer capable of DSP contol of :
• True 4-way integration with full-
range StudioLive AI models
• DSP-monitored temperature,
over-voltage, and
excursion limiting
• Multiple onboard delay setting
to optimize the 18sAI with three
common subwoofer positions
• Two DSP contours
Complete remote control.
The robust onboard CPU in the
StudioLive 18sAI makes possible
an extensive set of control features
for customizing and optimizing the
system and for monitoring and fine-
tuning performance in real time.
SL Room Control software for Mac
OS X, Windows, and iPad provides
the StudioLive 18sAl with wired and
wireless remote control of a variety
of features.

• DSP contours
