About the JL Audio 8W1v3-4

Legendary JL Audio engineering
When we think of subwoofers, we typically think of big speakers in large enclosures driven by high-wattage amplifiers. But sometimes you need bass in a smaller, more modest version. That's why JL Audio has created the 8W1v3-4 subwoofer, which fits in spaces where most subwoofers fear to tread.
Trickle down technology
This affordable 8" subwoofer incorporates patented features developed by JL Audio for their legendary W7 subs. Special venting keeps the sub running cool for trouble-free performance, while extensive research in cone bonding and motor assembly construction keeps its cone movement linear for precise, dependable output. The cone interlocks with the dust cap for superior rigidity, and a sophisticated suspension system keeps internal parts aligned properly when you're jamming hard.
At only 3-7/8" deep, this sub will fit in a lot of tight spaces.
Solid bass made for compact boxes
The low-profile 8W1v3-4 sub works best in compact enclosures, so you can put quality bass in smaller and hard-to-fit vehicles. Its shallow mounting depth of 3-7/8" allows it to live in compact environments, and it's been optimized to fit an enclosure with a volume of only 0.35 cubic feet.
The sub features a mica-filled polypropylene cone and an aluminum dust cap with an embossed JL Audio logo for a look that stands out as much as the sound. The removable, customizable trim ring lets you put a personal touch on your system, and makes optional grille installation a snap. This punchy W1v3 sub works well with moderate power, delivering impressive performance without costing a fortune. Haven't you got a cozy corner somewhere that needs some bumping bass?

Features
Woofer: The JL Audio W1v3-4 subwoofer features an injection-molded, mica-filled polypropylene cone with an embossed metallic JL Audio logo and a rubber surround for added durability, woofer excursion and bass response.
Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, W1v3-4 motors remain linear over a long excursion range, and also maintain a stable fixed magnetic field in the gap over a wide power range. The result is reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.
Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
Vented Reinforcement Collar: The Vented Reinforcement Collar (VRC) is a composite structure that addresses two issues related to reliability:
- Stress Relief: By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weakness. It does this by increasing adhesive contact area and providing stress relief to the spider material at excursion extremes.
- Air Flow: The VRC also features slots that facilitate air flow directly onto the voice coil windings, thus reducing thermal compression effects and enhancing reliability.
Insert Molded Suspension/Coil/Terminal Sub-Assembly: The W1v3-4 features a unique spider, coil and terminal subassembly, assembled prior to installation in the speaker frame for optimum alignment and glue-joint integrity. This type of assembly ensures precise lead wire length, lead wire entry and exit angles, and coil/spider alignment.
Elevated Frame Cooling System: The elevated frame design of the W1v3-4 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.
Customizable Trim Ring: The woofer comes with a removable ring made of black ABS plastic which can be painted to match the installation theme and create a personalized look. You can purchase an optional grille mesh insert specifically designed to fit into the inner diameter of the trim ring (item number 136SGR831, sold separately).
Enclosure Compatibility
Sealed Enclosure: JL Audio recommends an optimum sealed enclosure volume for the 8W1v3-4 of 0.35 ft³, resulting in a -3dB point of 59.9 Hz.
Ported Enclosure: JL Audio recommends an optimum ported enclosure volume for the 8W1v3-4 of 0.5 ft³. The recommended port is 2" (diameter) x 10" (long), resulting in a tuning frequency of 38 Hz and a -3dB point of 39.1 Hz.

Got this Sub to fit into my 2001 Ford Expedition Stock Sub Box with Stock Amp and I was amazed how the sound and power it produced. It hits like a 12". I had to utilize a .5" spaced ring to make if fit because of its depth but that it. I am over joyed with the results.
