JL Audio Black 8" Subwoofer Driver - 92079

JL Audio Black 8" Subwoofer Driver - 92079

The 8W1v3 is an outstanding choice when space is very tight and amplifier power is moderate. It features shallow mounting depth (3.86 in. / 98 mm) and a compact motor structure, allowing it to comfortably fit in a lot of spaces where a typical 8-inch driver will not. Lacking a pole vent, the rear of the motor structure can be placed directly against an enclosure boundary. Excellent excursion capability and linearity allow it to reproduce sub-bass with shocking extension and quality. Several of JL Audio's proprietary technologies enhance its performance and reliability.

The 8W1v3-2 is best used with amplifier power in the 50W - 150W range and is optimized to operate in a compact 0.350 cu. ft. (9.90 l) sealed enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.

Features:

• Dynamic Motor Analysis - DMA Optimized Motor
  JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.
• Elevated Frame Cooling (U.S. Patent #6,219,431 & #6,229,902)
  JL Audio's patented Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.
• Floating ConeAttach Method - FCAM™ (U.S. Patent #6,501,844)
  This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
• Vented Reinforcement Collar (U.S. Patent #5,734,734)
  JL Audio's patented Vented Reinforcement Collar (VRC®) improves the rigidity and stability of the cone/spider/voice coil junction and directs airflow over the voice coil windings for improved thermal performance.
• Insert Molded Suspension / Coil / Terminal Sub-Assembly (U.S. Patent #7,379,558)
  Spiders, voice coils, terminals and lead wires are preassembled, using a patent-pending process, onto a composite carrier for improved precision and reliability.
• Customizable Trim Ring (U.S. Patent #D480,709)
  This removable ring can be painted to match the installation theme and directly receives JL Audio grille mesh inserts (sold separately).
• Engineered Lead-Wire System (U.S. Patent #7,356,157)
  Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.
