Enclosed Subwoofer System with Single 8W3v3-4 Subwoofer Driver, Black Carpet (250 W, 4 Ω) - Ported Enclosure
This incredible MicroSub™ subwoofer system delivers the kind of output and extension that is normally possible with only much larger systems. The key to its performance lies in the precise tuning of its 8W3v3 subwoofer driver into an efficient slot-ported design.
Extensive interior bracing permits the use of thinner wall material that maximizes the enclosure's internal volume relative to its exterior volume. The port wraps around two walls of the enclosure to produce the necessary low tuning frequency that ensures excellent extension and response smoothness. The flared port entry and exit further enhance sound quality by minimizing air-flow noises through the port.
This subwoofer system is shipped wired, loaded and ready to connect via a five-way binding post terminal.
Finish: Black, high-grade automotive carpet with silver "JL AUDIO" embroidery on front baffle. A steel mesh grille is included to protect the subwoofer driver.
Construction: CNC-Cut High-Grade MDF
Recommended amplifier power: 100 - 250WTechnologyV-Groove MDF Construction
Nominal Impedance: 4 Ω
This advanced cabinet-building technique uses CNC-machining to create precise panel joints that make enclosure assembly more efficient and exact.Flared Slot-Port
The flared slot-port design reduces turbulence at the port mouth so as to minimize any audible airflow effects common to ported enclosures.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 Cone Attach 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
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 patent-pending 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.
