Product Description

W12GTi MkII The JBL W12GTi MkII 12-inch (300mm) subwoofer is nothing short of amazing. Using technology from the JBL professional audio division, this sub features the patented Differential Drive � Design (US patent no 5,748,760 and other patents pending) motor that uses opposed dual voice coils in a neodymium magnetic field and handles an amazing 4,000 watts peak power (700 watts RMS). Other high-tech materials include a cast-aluminum frame, Kevlar® cone and nitrile butadiene rubber (NBR) one-piece surround. This sub represents the best 12-inch (300-millimeter) car subwoofer that money can buy. It’s the 12-inch reference standard. Nothing else even comes close. Select features to learn more: 25 – 4000 watts suggested amplifier power range 25 � 4000 watts suggested amplifier power range JBL engineers designed the W12 GTi MkII subwoofer to produce uncompromising, mammoth bass from an amplifier capable of delivering up to 4000 watts of power. This is nothing short of incredible. What � s more incredible is not just how much power this subwoofer can handle but how it handles the power by using patented, high-tech materials. In the end, this sub is the 12-inch (300-millimeter) reference standard for car audio subwoofer technology. Nothing else even comes close. Patented Differential Drive Design (DDD) motor Patented Differential Drive Design (DDD) motor JBL W12GTi MkII subwoofers employ Differential Drive Design (DDD), a patented technology developed by the JBL Professional Audio Division. Differential Drive Design employs two 3-inch (76-millimeter) voice coils, each suspended in a separate magnetic gap. At low power, both voice coils drive the subwoofer ��s cone, and any motor nonlinearities are cancelled. As power input increases so that one coil rides completely out of its gap, the other coil still applies force to the cone for significantly higher power handling. Rare-earth neodymium magnet Rare-earth neodymium magnet One of the breakthroughs in speaker design is the use of neodymium instead of heavier ferrite materials. Typically, audio makers use small amounts of neodymium in tweeters and midrange drivers. JBL engineers use generous amounts of neodymium in the W12GTi MkII subwoofer to ensure much greater magnetic-energy density. As a result, this subwoofer provides superbly accurate cone movements. It delivers a high degree of control that is virtually without comparison among car subwoofers. Kevlar-impregnated paper woofer cone Kevlar-impregnated paper woofer cone The Kevlar fiber is a well-known composite material that the military and law enforcement use for bulletproof vests and combat helmets. JBL W12GTi MkII subwoofer uses this rugged material in its cone. Since Kevlar material is extremely lightweight yet rigid and stiff, it� s the ideal cone material to move large amounts of air without flex or distortion. NBR (nitrile butadiene rubber) surround NBR (nitrile butadiene rubber) surround Nitrile butadiene rubber � commonly known as NBR � is a tough industrial gasket material. W12GTi MkII subwoofers use a single-piece surround and mounting NBR gasket that provides a complete seal between the front and back of the subwoofer � an essential design feature when you consider the high pressure levels that develop within subwoofer enclosures. NBR is also environmentally stable under a wide range of conditions and temperatures, which ensures that the subwoofer will replay sound in your car equally well during the summer or winter. Die-cast, vented aluminum frame Die-cast, vented aluminum frame JBL engineers designed the W12GTi MkII subwoofer’s proprietary die-cast aluminum frame from the ground up. Unlike the � �off the shelf� frames in some other subwoofers, this sub ��s aluminum frame features significant venting and heatsink fins to add power handling. And since aluminum is a rigid material, it keeps the critical voice-coil components in perfect alignment while they travel through the linear-excursion range. Progressive spider Progressive spider The W12GTi MkII subwoofer� s progressive spider provides restoring force to the cone in varying degrees, depending on the amount of excursion � hence the name progressive. The spider allows the cone to move easily under subtle music conditions, which results in a more musical subwoofer. By progressively adding more restoring force as movement increases, the spider ensures that the cone travel is always controlled, under even the highest excursion conditions. Dual 6-ohm voice coils Dual 6-ohm voice coils Conventional dual-voice-coil woofers use a pair of voice coils wound on the former and layered over the top of one another, and then both voice coils are centered in the speaker� s magnetic gap. The W12GTi MkII subwoofer� s voice coils rely on a push-pull system, each using its own magnetic gap. The two coils may be connected in series or in parallel to maximize an amplifier� �s output power. A Differential Drive Design (DDD) motor relies upon magnetic braking, which prevents damage from over-excursion. Insulated tinsel leads Insulated tinsel leads Tinsel leads carry ab audio signal into the voice coil. Because the W12GTi MkII subwoofer� �s tinsel leads are fully insulated, you need not worry about any arcing or electrical shorts. It ��s just one more detail that makes this subwoofer such a mechanical wonder. Gold terminal jumper binding posts Gold terminal jumper binding posts The W12GTi MkII 10-inch (250-millimeter) subwoofer features rugged, gold-plated binding posts for the speaker-wire connectors that accept the large-gauge wire commonly associated with high-power subwoofers. With positive terminals placed on one side and negative terminals on the other, this subwoofer features a unique jumper system: A single input terminal connection is needed for parallel (3-ohm) or series (12-ohm) configurations.

W12GTi MkII A patented, cast-frame 12"" (300mm) DVC subwoofer with 4000W peak power handling Review

This sub lives up to every 5 star review. It is a total beast and produces some incredibly detailed bass. I have 2 now - one in a sealed 1 cubic foot box as suggested by JBL for optimal sound accuracy and another in a tank of a ported bassworx box. Both are made of 1" mdf. Thick heavy beastly bass boxes. I have a 2000 watt mb quart amp feeding them and it seems adequate but they could handle more.

If you have the room, and the budget for getting a sub of this calibre and putting in the cash for a good amp, 0 guage wiring and solid enclosures with zero vibration issues.... don't mess around with other brands. These look super classy and pack a monster punch.
