The Force Powered Subwoofer

Thank you for your order and congratulations on becoming the owner of an ACI speaker

system. The Force powered subwoofer(s) will provide you with many years of listening pleasure!

ACI’s Force is a compact, yet potent subwoofer. The Force is based on the subwoofer

technology of our legendary Titan series. An extreme excursion 10" driver is powered by our

proprietary amplification using special circuitry to essentially cut the required box volume in half!

Many subwoofers do a respectable job with explosions, shotguns, and crashes. The market

is loaded with black boxes and tubes that beg to be "hidden". The Force is different. Compact, yet

attractively built to compliment your fine furniture. The Force will rattle your china. More importantly,

it will allow a seamless and completely transparent blend with your main speakers. Your sound

stage will be enhanced, not degraded. Instruments like acoustic and electric bass, piano, and

percussion will come through with vivid realism. The Titan II LE has earned a reputation of being one

of the most musical subs available at any price. The Force continues this tradition of musical

excellence in a smaller cabinet, at lower cost.

The internal enclosure is constructed of ¾” non-resonant high-density fiberboard with

extensive internal bracing. The mounting for the downfiring woofer is 1.25" thick for additional

resonance control and stability. Solid hardwood panels coated with multiple layers of clear or black

lacquer grace the exterior and add additional damping. For even higher output levels, multiple Force

units may be stacked.

Performance

The electronics of the Force performs the following functions:

• Gain is controlled at the INPUT LEVEL with a precision Alps pot. This also acts as the volume

control for the Force. Once the volume is set, your volume is controlled by your main system.

Note: When using the Theater Input the volume on the Force is bypassed and will be controlled

by your processor.
