EUROLIVE VQ1800D and VQ1500D active
subwoofers are ideal for adding serious
bottom end to DJ and club rigs. Packed with
an incredible array of professional features,
these little powerhouses provide lots 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. Best of all, VQ1800D
and VQ1500D subs provide a much
better power-to-weight ratio than many
competing active subwoofers. Powered by
500 Watts both the 18" and 15" versions
feature custom-designed transducers
made in our own factory.

Put simply, these cool-running systems
are powerful and lightweight, making them
easy to transport and set up—and our
no-compromise design means you get
amazingly-tight, chest-pounding bass
that will keep the party going all night.
Adding VQ1800D and VQ1500D subwoofers

will transform your active full-range
loudspeakers into a powerful PA system
with serious dynamic punch.

Class-D Technology

Instead of operating relatively
continuously like Class AB circuits,
Class-D amps are either fully on or fully o,
signicantly reducing power losses given
o as heat. Less heat generation means our
amps don’t need massive heat sinks and all
that unnecessary added weight. Our no­compromise design allows VQ Series
subwoofers to deliver full power with
incredible delity all night long.

When used in conjunction with
switching-mode power supplies,
which don’t require huge and heavy
transformers, our VQ Series’ Class-D
ampliers provide tremendous punch and
superior delity. 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 corners.
We custom-design and build our transducers
from scratch. Not only do we wind our own
voice coils—we even process the paper pulp
into cones and machine our own back plates.
This enables us to control the quality,
and frankly, make better components.

Take Control

The VQ1800D and VQ1500D feature
balanced XLR inputs and outputs, as well
as balanced XLR Thru jacks for connecting
additional enclosures. A Boost Frequency

knob targets a frequency between 40 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
(70 – 150 Hz) for the subwoofer’s amplier.
The High Cut dial does not aect the Thru
or Output signals, only the signals directed
to the subwoofer. 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 Limit.

Which Speaker Do I Need?

As you have probably noticed, we make
VQ Series subwoofers in two dierent
woofer sizes. Which one is right for you?
Bass speakers, such as the kind used in

subwoofers, create punch and impact by
moving air. An 18" woofer has about 30%
more surface area than a 15", so it can
move a much larger column of air. If you’re
running sound for a small jazz combo in a
nightclub, a single VQ1500D might be all
you’ll need. But, if you’re providing a pulse­pounding dance mix to a large standing
room only crowd, you might need a pair of
VQ1800Ds, or more to get the job done.
