Our EUROLIVE B1500D-PRO and
B1800D-PRO active subwoofers are
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
denition and clarity typically reserved for
much larger systems.

Class-D ampliers (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
and B1500D-PRO are powered by 1400
Watts—in your choice of 18" and 15"
versions. As always, the speakers are
made by BEHRINGER in our own factory.

Put simply, these active subwoofers
provide massive connectivity options and
are easy set up—and our no-compromise
design means you get amazingly-deep,

chest-pounding bass that’ll keep the
party going all night long. They’ll add
serious 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 o thousands
of times per second, delivering power
only when needed. In other words,
the amplier is either fully on or fully o ,
which signicantly reduces power losses
from the output devices given o as heat.
Our no-compromise design means the
B1500D-PRO and B1800D-PRO will deliver
full power with incredible delity all
night long, without the need for lengthy
rest cycles. When used in conjunction
with switching-mode power supplies,
our “green technology” Class-D ampliers
provide tremendous dynamic punch and
superior delity.

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 here. We use the most
advanced, computer-based Klippel
and MLSSA systems in our design
and manufacturing process, ensuring
that our transducers provide optimal
performance within their specied
application. We custom-design and
build our transducers from scratch;
winding the voice coils, processing
the paper pulp into cones—and even
machining the backplates. This enables us
to control the quality, and frankly, to 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 amplier. The HIGH-CUT
dial aects only the signals directed
to the subwoofer. The Output A and B
sockets have a xed 100 Hz low-cut lter
to facilitate connecting full-range active
loudspeakers. 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 dierent
woofer sizes. Which one is right for you?
An 18" woofer has 44% 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.
