The JL AUDIO Fathom F212V2 is a dual 12-inch behemoth offering jaw-dropping levels of sub-bass performance in any size of room. For best performance as with any subwoofer, Sydney Hi-Fi Castle Hill recommends at least two subwoofers to maximise bass response.
The challenges associated with designing high-output, compact subwoofer systems can be daunting. In most cases, designers sacrifice low-frequency extension or output capability in order to keep a design acceptably small. The Fathom® subwoofers sacrifice nothing, thanks to the
dynamic advantages of their proprietary JL Audio drivers. These exceptional woofers 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 design, each Fathom employs an uncommonly 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 theatre applications, including built-in designs. Front-mounted controls make them comfortable to set up and adjust, while JL Audio’s powerful DSP engine and exclusive Digital Automatic Room Optimization makes sure that response is smooth, even in challenging rooms. The f212v2’s dual-driver configuration and ultrapowerful amplifier deliver the highest performance of the Fathom lineup. This subwoofer is the top choice for those seeking best-of-the-best performance in a conventional form factor.
