The challenges associated with designing high-output compact subwoofer systems can be quite daunting. In most cases, designers 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 a true subwoofer passband 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 large toroidal transformer and 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. Simply put, Fathom is the compact subwoofer system for those who enjoy demanding program material and won't settle for compromises.

what reviewers are saying about JL Audio ...


"What are they, exactly? I can't answer that in a nutshell. Not if you want more specific than fantastic.  The condensed version is that they are relatively small, insanely well-built, extremely powerful, very smooth, tight, detailed to a fine line, clean, poise-laden, dynamically proficient, utterly kick-ass subwoofers. (Colin Miller, Secrets of Home Theater and High Fidelity)

"The JL Audio Fathom 113 dollar for dollar is the best subwoofer I have heard on the market. If you are in the market for any of the top-of-the-line audiophile products, you owe it to yourself to go out and take a test drive with the Fathom 113. It has the power to knock your socks off. It has the finesse to make your best speakers sound even better. (Michael Levy, AudioVideo Revolution)

 

 


 
"Two JL Audio Fathom f113 subwoofers produced dramatic changes in my audio system. Never before had new audio gear reshaped the depth and width of the soundstage, doubled the dynamic range, and increased the transparency, all at the same time.
 
The Fathoms’ reproduction of double bass had ear-boggling dynamics and pace. (Larry Greenhill, Stereophile, September 2007)
"The JL Audio Fathom is of reference quality and a benchmark by which all other subwoofers can be judged. (Robert Harley, The Absolute Sound, March 2007)
 

 


 
"Living with the Fathom was like chatting with the smartest and most agreeable guest at a party full of blowhards. Action movies lost that one-note quality that so often leads to irritation and boredom. The bottom end of pretty much any kind of music took on more definition and shape, even with the lowest string of the lowest instrument. Suddenly relieved of bad-sub stress, I became less stressed. I felt a renewed appreciation for artists and engineers because I could hear more of what they'd intended me to hear. Over time, my expectations changed. I now have a broader frame of reference for what a sub can accomplish. This will not make subsequent reviewing any easier. Couldn't I just stay here forever?
(Mark Fleischmann, Home Theater Magazine, April 2007)
"...the JL Audio guys are serious audiophiles who have both the technical know-how and manufacturing wherewithal to build world-class subwoofers.
(Chris Martens, The Perfect Vision, February 2007)
