JL Audio 8" Subwoofer Driver - 010-03036-00

JL Audio 92148 8" Subwoofer Driver

If you need an 8-inch subwoofer that can create outstanding bass in extremely small enclosures, the 8W3v3 will do the job and surprise you with its power and accuracy. It employs the same technologies as its larger diameter brethren to deliver a whopping 0.375 in. (10 mm) of controlled, one-way, linear excursion.

The 8W3v3-4 is best used with amplifier power in the 75W - 250W range and is optimized to operate in a tiny 0.30 cu. ft. (8.5 l) sealed enclosure, or a 0.35 cu. ft. (9.9 l) ported enclosure.

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
  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 Cone Attach Method - FCAM™
  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
  JL Audio's 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 patented process, onto a composite carrier for improved precision and reliability.
• Customizable Trim Ring
  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.
• Built in U.S.A. with Global Components
  JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.

Footnotes:

• * Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
• ** Efficiency (1 W / 1 m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”.
