PRODUCT DESCRIPTION
The Snell AMC Sub 10serves one simple function – it extends the bass response of an audio
system down to the limits of audibility. In doing so, it gives the system the sonic foundation
needed to deliver the full impact of movie sound tracks and the deepest fundamentals of
music. Just as impressive as the bass extension the Sub 10provides, is the fact that it can be
mounted in any wall constructed of standard 2” x 4” lumber mounted on 16”
centers.
The AMC Sub 10is truly an exceptional value. A specially designed cast-frame 10” woofer
permits long linear excursion resulting in excellent frequency response and dynamic range for
bass performance that can be felt as well as heard. Many other subwoofers designed for custom
installation use the space inside the wall for an enclosure. The size and shape of that space, and
amount and type of insulation that may be in the wall, dramatically affects the sound the
speaker produces. In contrast the AMC Sub 10is a complete enclosed system. This ensures
consistant, predictable performance.
When the goal is to make the subwoofer disappear, leaving only the impact of the audio/video
sound track, or the deepest musical fundamentals, the AMC Sub 10is the ultimate choice.

Placement
Placement of your new AMC Sub10is very important in achieving the smoothest possible bass
response. The design of the AMC Sub 10allows for many installation options. While the
traditional subwoofer cabinet is vertical with the woofer toward the bottom, the AMC Sub12
can be placed on its side, vertically with the woofer toward the top, or even in the floor or
ceiling.
One of main things to do when selecting an installation location is to avoid places that are
symmetrical with the dimensions of the room. This helps avoid peaks and dips in the response
of the subwoofer. (These response errors are the result of the bass sound waves interacting with
the room – reinforcing some frequencies and canceling others.)
A useful placement guideline is the “rule of odd fractions”. This means that you should try to
place the subwoofer 1/3 or 1/5 of the way along the wall. Take for example, a wall that is about
20 feet long. It has 15 between-the-stud spaces. The Sub 10should never be mounted in the
eighth space – that would put it in the center of the wall. Rather it should be mounted in the
third or fifth space – putting the subwoofer 1/5 or 1/3 of the wall along the wall.
In some situations, it may not be possible to install the subwoofer into a wall. In this case the
ceiling, floor, or even a closet are options. Wherever the AMC Sub 10is installed it must be
securely mounted. If it is not securely mounted, its substantial bass output may produce rattles.
In addition, be sure that the connectors are accessible for electrical hook-up.

Preconstruction Information
The AMC Sub10 is 53” high by 14 3/8” wide by 3 13/32” deep. Locate the best position
acoustically as well physically due to room constraints.
Detach the New Construction Bracket (NCB) by unscrewing the 4 bolts that hold it to the
cabinet. Detach the woofer by unscrewing the 4 bolts that hold it to the cabinet.
Attach the 4 brackets to the cabinet with supplied 1 ¼” wood screws. The AMC Sub10
should be solidly coupled to the studs on either side of the cabinet and to the drywall in
front of it. To help achieve a solid coupling, apply a rope-type window caulking material
between the sides of the cabinet where they meet the studs and to the front of the cabinet
above the woofer. This will help prevent rattling while the Sub10 is operating.
With the brackets now attached to the cabinet, attach the whole assembly to the 2”x4”
studs with the supplied 1 ¼” wood screws.
Feed the speaker cable from your amplifier to the Sub10 cabinet. Two holes are provided
at the top of the cabinet for cable routing. Four grommets with two different size cables
are provided to provide an air seal and hold the wires in place.
Next, connect the speaker cable to the woofer, being careful to observe polarity markings.
Install the woofer and use the 8 machine screws supplied to fasten the woofer.
Install the NCB (with the hole facing the woofer) with the 4 supplied machine screws.
Using the NCB as guide for drywall cutting, cut a ~14” square (15” from bottom of
cabinet). Remove the NCB.
A grille solution will be available in Spring 2004.

LISTENING LEVELS AND POWER HANDLING
The power recommendation for the system assumes you will operate the amplifier in a way that
will not produce distortion. All speakers can be damaged by even a modest amplifier if it is
producing distortion. If you hear a gritty noise or other signs of strain, turn down the volume.
Prolonged or repeated operation of your speakers with a distorted signal can cause damage
that is not covered by the warranty. It is especially important that you do not overdrive the
bass capability of smaller speakers. Watch for noises, such as pops, caused by the music’s bass
line. Use of the loudness control and/or full bass boost at louder volumes is likely to overdrive
the woofer. Use such controls sparingly.
HOW TO CARE FOR YOUR SPEAKERS
Use a soft terry cloth towel slightly dampened with water, glass cleaner, or a diluted mild
detergent. The towel should be just damp enough to wipe the surface clean without leaving
a trail of moisture.
Do not use abrasive cleaners or any cleaner containing chemicals harsher than those found
in glass cleaner.
