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.
