INTRODUCTION
The ICS Sub12 provides 1st octave bass with exceptional speed and output. The enclosure, while
versatile in shape, is a 4th order vented enclosure. Its passive design enables a system design
with a remote mounted amplifier, allowing for the amplifier’s performance characteristics to
optimize the subwoofer’s capabilities. The heart and soul of the ICS Sub12 is a specially
designed 12-inch cast frame woofer and motor structure, capable of extremely long linear
excursion. In an average room, one ICS Sub12 is enough to deliver truly awe inspiring bass.
FEATURES
Gold Plated Input Terminals
These high quality terminal accept spade terminals, pins, banana plug and bare wire to 12
gauge
Bass Driver

M3 ) in volume.
Handmade Cabinets
Our cabinet department hand assembles each unit, and then hand sands each several times. The
result is a cabinet of exceptional workmanship, with sharp corners and smooth sides.

PLACEMENT
Typically the ICS Sub 12 will produce the smoothest response when placed against a wall.
Placement in a corner will further enhance bass output allowing you to run operate the
subwoofer at a lower power level. Experiment with subwoofer placement before settling on a
placement location.
Choose a musical selection with a heavy and continuous bass line. Play a short section several
times until you have a firm impression of it in your mind. Then try another location to see if it
provides smoother or more balanced response . Repeat this process until you are content with
the bass response you are getting. Strive for a smooth, solid bass response that does not
emphasize any part of the bass range.
Note: Avoid placing the ICS Sub 12 close to a television or monitor. There should be at least 8
inches (20cm) between the two components. If getting the best sound, together with the
physical constrains of the room, require that the two units must be closer than that you can
purchase a magnetic shielding kit from Snell Acoustics.
CONNECTION
The terminals of the ICS Sub 12 accept spade terminals, pins, banana plug or bare wire to 12
gauge. Be sure to connect the positive (+) amplifier terminal to the RED binding post of the
Sub12, and negative (–) amplifier terminal to the BLACK binding post, to achieve the correct
polarity. All wire has a stripe on one side, or ridges molded into the insulation, or some other
marking to make it easy to trace the connections to be sure the wire is properly connected.
