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 specified 
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.

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 amplifier. The HIGH-CUT 
dial affects only the signals directed 
to the subwoofer. The Output A and B 
sockets have a fixed 100 Hz low-cut filter 
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.

As you have probably noticed, we 

make these subwoofers in two different 
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.

Internal switch-mode power supply
