The challenges associated with designing high-output compact subwoofer systems can be quite daunting. In most cases, designers choose to sacrifice low-frequency extension or output capability in order to keep the design small.

The Fathom subwoofers sacrifice nothing thanks to the dynamic advantages of their proprietary JL Audio woofers. These exceptional drivers allow for full bandwidth and very high output while keeping distortion well below audible thresholds.

To extract full benefit from the excursion envelope of its woofer, each Fathom employs an exceptionally powerful switching amplifier with a patented circuit designed to enhance control and fidelity.

The compact design and conventional form factor of the Fathoms apply beautifully to most home theater applications, including built-in designs. Front mounted controls make them a dream to set up and adjust, while JL Audio’s exclusive Automatic Room Optimization circuit makes sure that response is smooth, even in challenging rooms.

	Fathom: A.R.O.

Automatic Room Optimization:

A wise man named Murphy long ago prescribed that a subwoofer will generally sound best in the most impractical spot in the room... a fact that home theater professionals wrestle with all the time. Subwoofer placement almost always involves a compromise between sonic performance, practicality and aesthetics.

To face this dilemma head on, JL Audio Fathom subwoofer systems incorporate a clever piece of technology called Automatic Room Optimization (A.R.O.).

The A.R.O. system self-generates a series of calibration tones, measures the response at the listening position, analyzes the shape and magnitude of the primary response error and configures an appropriate analog filter to tame it. The system effectively allows for smooth, well-balanced sub-bass from a variety of locations that may have been less than optimum without A.R.O.
