Your Fathom combines these core disciplines within a compact, beautifully crafted package to deliver an unparalleled listening experience.

JL AUDIO TECHNOLOGIES INCLUDED IN FATHOM SUBWOOFERS

DMA-Optimized Motor System

DMA is JL Audio’s proprietary Dynamic Motor Analysis system aimed at improving dynamic motor behavior. As a result of DMA optimization, loudspeaker motors remain linear in force over an extreme range of excursion and also maintain a highly stable fi xed magnetic field over a wide power range. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

OverRoll™ Surround

(U.S. Patent #5,687,247 and #5,949,898) The OverRoll™ surround spans over

the driver’s mounting flange, utilizing available diameter wasted in conventional speakers. This allows the use of the wider roll necessary to control high-excursions without sacrificing precious cone area.

W-Cone™ (U.S. Patent #6,496,590) The W-Cone™ is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass.

Floating-Cone™ Attach Method (U.S. Patent #6,501,844)

This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

Plateau-Reinforced Spider Attachment (U.S. Patent #6,118,884)

This high-integrity suspension attachment relieves stress from the spider material at high-excursions for enhanced reliability.

Elevated Frame Cooling Technology (U.S. Patent #6,219,431 and #6,229,902)

Delivers cool air, through slots directly above the top-plate, to the voice coil of the speaker. This enhances power handling and sound quality by minimizing dynamic parameter shifts and power compression.

Radially Cross-Drilled Pole Piece (U.S. Patent #6,243,479)

This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame technology.

High-Damping Feedback Circuit (U.S. Patent #6,441,685)

This proprietary, discrete control circuit design allows our Class D switching amplifiers to maintain an excellent damping factor for improved transient behavior and fidelity.
