SB-Series Box Subwoofers
The Atlantic Technology powered subwoofer
has been engineered using the latest technology
and finest components available.
High-Performance Drivers – Long-throw composite
cone drivers with vented motor structures and oversized,
high temperature voice coils. These powerful drivers have
very stiff cones that act like a pistons throughout their
operating range. Their massive motor assemblies and
high temperature component parts deliver exceptional
performance and reliability.
Sealed Enclosure Design – Sealed enclosure woofer
designs are inherently low in distortion, and deliver deep
smooth bass response with a gradual and predictable
roll-off below resonance. As with all Atlantic Technology
subwoofers, we have paid close attention to providing
accurate musical bass reproduction along with terrific
special effects.
High-Current Amplifiers – The output stages of these
amplifiers are capable of very high current delivery for
exceptional driver control and cool operation. They have
been precision matched and equalized to our rugged
drivers.
Together they deliver powerful, controlled bass with great
articulation and authority, with a useful in-room working
frequency range of 25Hz to 150Hz.
Many subwoofers offer specifications that look great on
paper, but in the real world deliver less than promised.
Atlantic Technology subwoofers are over-designed to ensure

that they will deliver their rated performance in your room,
when properly placed and adjusted.
Adjustable (40Hz to 140Hz)@18dB per Octave Low
Pass Crossover – The steep upper end roll-off slope of
18dB per octave allows for much better bass integration
with the satellite speakers while making the woofer less
localizable.
Complete Hookup Flexibility – The subwoofers each
have two low level inputs and two low level outputs. The
outputs allow daisy chaining of multiple subwoofers, or as a
return path back to the processor.
Phase Invert Switch – This switch allows precise
acoustic matching with satellite speaker systems whose
output may be phase reversed. This switch also allows you
to compensate for unusual room acoustics that occur when
the woofer is physically separated from the main speakers.
Front Panel Level Control (642 and 422 SB) –
Allows convenient adjustment of subwoofer level.
Automatic Standby Operation with LED Indicator
Automatic standby features signal sensing turn-on with
a 7-10 minute turn-off delay. There's a multi-color LED
status indicator that lets you know when the unit is on or in
standby. Automatic Standby can be defeated by placing the
rear-mounted switch in the ON position.
