JL Audio’s Fathom F212 V2 is the best dual 12″ driver subwoofer in the World in our opinion, it really is unrivalled in its class and classes above it. Nothing competes at this price point of £7499




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 theater 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 ultra-powerful 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.

    I have had the F212 V2 for a few weeks and i must say this is one hell of a sub,
    and even more so after Ideal-AV set the sub up, ie: placement/levels/phase alignment.
    “i must say that customer service is second to none”
    I have had many subs in the past from single to duel and even x4, from MA/MK/KK/Arendals and none of them came close to how the f212 v2 handles the room, super fast/deep/clean bass, “it punches harder than Tyson ever did” a must have sub (*****)+
