The Automated Controlled Environments, Inc. Subwoofer Optimizer System (SOS) is an automatically
calibrating, subwoofer optimization component that acts to attenuate an audio system's major room
mode resonance to provide significant improvement in measured and subjective bass system perfor-
mance. After installation and calibration, your system will have a more linear frequency response, bass
evenness, tightness, extension, and improved sound clarity.

Introduction
The Subwoofer Optimizer System makes use of a unique process which combines processor controlled
digital operation with Analog Signal Processing (ASP) technology. The digital circuitry is used to set the
calibration level, generate test tones, identify room resonances, and set filter parameters. The unit
performs this procedure automatically using the special calibration microphone, which is included with
the system. When the calibration procedure is complete, the digital portion of the unit’s circuitry is
turned off. This way, it won’t interfere with the analog signals passing through the unit.
The following graph from a spectrum analyzer output plot demonstrates the effect of the SOS’s ASP
technology on an actual subwoofer in a large room. The upper line represents the subwoofer’s response
from 20 to 80 hertz with a constant input. The curve shows a broad hump (major room mode resonance)
between 30 and 80Hz.
