Introduction
Thanks for choosing the Model-One Subwoofer. Your Subwoofer is perfectly
matched both sonically and aesthetically to the Model-One Turntable Music
System. It may be used standalone with its beautiful tempered-glass top, or
integrated with the Model-One stand system to create a full range music system
with the smallest possible footprint.
While optimized for use with the Model-One system, it is also a great choice to
use as a companion to a high-quality audio system of any brand to extend its low
frequency performance.
Unlike common home-theater subwoofers, the Model-One Subwoofer design
prioritizes smooth frequency response and accurate impulse response over
sheer loudness. Its twin 10” Woofers in a sealed Acoustic Suspension design
provide smooth, extended bass response that perfectly matches the Model-One
Music System.
To get the most from your system, be sure to thoroughly review this manual and
heed the important safety instructions. If you have any questions not covered
here please contact Andover Audio support via email (support@andoveraudio.
com) or phone (+1 978.775.3670).
With the proper care and operation, your Andover product will provide many years
of trouble-free enjoyment.
Please save the carton and original packaging in case you ever need to move or
ship your unit.

bass from a given listening position. Understanding how these standing waves
work within your particular room is important to get the most satisfying overall
performance. Moving the subwoofer a few feet either way can have a dramatic
effect on perceived bass response. Each room is different, so experimentation in
The symmetry resulting from placing the subwoofer directly in the center of a
is usually best to place the woofer a few feet to either side of center.
Corner placement will yield the strongest reinforcement of bass within the room,
but may also further exacerbate standing waves. You will need to try various
locations to determine what location works best on your particular room.
Your Model-One Subwoofer uses a digital crossover with a very sharp cutoff
above the selected frequency. This makes it possible to separate the subwoofer
location from the Model-One Turntable Music System by up to 12 feet and still
maintain a smooth blend with the main speakers. Once you have determined

When you install the Model-One Subwoofer as an integral part of the stand,
locate the Model-One system where for the best full range sound, as outlined
in the Model-One Turntable Music System manual. Placing the system near the
center of a wall, but not perfectly centered, will likely yield the best overall sound.

Subwoofer Setup
Install the four adjustable feet in the four bottom corners of the subwoofer by
screwing them into the threaded inserts. These may be adjusted slightly to level
To use the Subwoofer separately:
1. Carefully remove the tempered glass top from the foam packaging and
gently place it in the recess in the center of the top frame.
2. the volume control
away from its center position to match the output from the Model-One Music
System from your listening position.
1. Remove the 4 screws holding the
top panel to the subwoofer for
shipping and put aside the top.
To integrate the Subwoofer with the stand:
2. Remove the
subwoofer grille
by pressing on the
grille from the back
on both sides. Slide
the grille straight
forward.

3. Prepare the top stand by
installing the 4 cam-lock pins
into the innermost threaded
holes. Screw them in fully, but do
not overtighten. Also press the
wooden alignment dowels fully
into the larger adjacent holes.
4. Place the top stand on the
subwoofer, being careful to align
the pins into the proper holes.
5. Insert locking cams into each
ofthe four holes and lock them by
turning the cams clockwise until
they stop.
6. Reinstall the grille by sliding it
carefully from the front until it is
fully seated.
7. Adjust the leveling feet if needed
to level the assembly.

Making the Initial Connections
1. Connect the power cord into the AC power input connector and plug the
other end into a grounded wall outlet.
2. Connect an RCA cable from the Subwoofer output of the source component
into the RCA jack input.
3. Switch the power switch adjacent to the AC input ON.
4. Switch the Power mode switch to the AUTO (middle) position.
If using the Model-One Turntable music system, set the Volume and Frequency
knobs to their center detent position. This is our factory-recommended setting.
Once the system is installed and operating, you may freely adjust these controls
to your taste.
The LED adjacent to the Power Mode switch indicates operating status. A Red
LED indicates the subwoofer is on and in Standby. When a signal is present,
the LED will turn green and the subwoofer will be active. After a few minutes of
silence, the woofer will return to Standby.

Adjusting Level and Frequency
The centered positions of the level and frequency knobs represent the ideal
starting point when the subwoofer is used with the Model-One Music System. It
should provide an ideal match when the subwoofer is used as the lower section
of the stand.
If the subwoofer is placed separately from the stand, or if using a source other
than the Model-One Music System, you may may need to adjust the settings
away from the default.
Adjust the subwoofer level as desired to balance the bass level with the rest of
the system from your listening position. Please note that excessive bass boost
might result in excessive distortion, and in extreme instances may induce feed-
back despite Isogroove technology. Increasing volume level beyond the detent
(centered) position should be done in moderation. For the most musically satis-
fying performance, the volume should be set to a level that the subwoofer does
not sound like it is a separate speaker. It should blend smoothly with the primary
sound and not draw particular attention to itself.
feel the need for more mid-bass to add weight to male voices and electric bass,
turn the frequency knob a few degrees clockwise. This will increase the upper
bass reinforcement from the subwoofer. Alternately, if you would like to reduce
the upper bass, without affecting the very low bass, turn the frequency knob
counterclockwise. We strongly believe that this adjustment is best done by ear in
If your source component is a home theater receiver with a subwoofer output, set
the Model-One Subwoofer frequency control fully clockwise, and use the cross-
over settings on your receiver or processor to set the frequency.
Many people initially adjust their subwoofer unrealistically loud, and end up
turnor processor ing the level down as time passes. We recommend starting
from the centered position on both controls, give yourself some time to get used
to the sound with these settings, then adjust them gradually over time until you
achieve the balance that suits your preference.

Isogroove Technology
Isogroove is our name for the suite of design features that reduce the generation
and subsequent transmission of mechanical vibrations through the structure of
the product. This reduces the liklihood they will be picked up by the turntable’s
stylus, resulting in feedback. Andover products featuring Isogroove have been
tested in a variety of locations and proven to be very effective when used as
intended. There are some rare instances where feedback might still occur,
despite the effectiveness of Isogroove technology.
1. Airborne sound waves may vibrate the stylus directly, and not through
mechanical vibrations within the product that Isogroove addresses. If this
occurs, you may need to reduce the volume level of the subwoofer or move
the subwoofer further away from the Model-One Turntable Music system.
2.
eventually into the turntable. It may be necessary to experiment with
structure vibrations.
Please note that these ocurrances are not failures of Isogroove technology
but are the result of uncommon installation conditions external to the product.
These problems can generally be resolved by moving the components within the
room or relative to each other.
