Not only are its ingenious technical solutions impressive, but also its sonic abilities which leave no desire unfulfilled. Product that has been physically abused (run over by a car or beat with a hammer, for example).\u003cbr\u003e4. A further benefit is that the mounting holes are inherently sealed by the surround, resulting in an improved box seal. This means that we can use a large roll for all its benefits without sacrificing cone area (in fact, the 12W7 has 1% more piston area than the medium-surround conventional woofer). Coverage may be invalidated as this date is previous to purchase date. “Simply put, the JL Audio 8W7 is the best damn 8-inch subwoofer ever made.”, “...if you're looking for big audiophile sound in a package that requires a small amount of power and space, the JL Audio 8W7 isn't a good choice, it's the only choice.”, – Paul Sonoda, Car Sound and Performance, June 2004, "You'll be amazed at the sound produced — it's smooth, deep and musical but can also be played to hurt… You've simply got to hear the new W7…", "You'll need to buy two or even three subs of a similar size to make the same (output) and you probably won't have room for them. The force is not only applied to the apex but also distributed to the perimeter of the outer diaphragm for more linear behavior. Since most of our premium loudspeakers incorporate proprietary, patented technologies requiring specific assembly techniques, we find it is vital that the people who designed them have close access to the people manufacturing them. A minimum distance of 0.75 in (19 mm) is required between the back of the speaker and any wall of the enclosure to allow proper operation of the pole vent.\u003c\/p\u003e\n\u003cp\u003eThe dimensions given for the enclosure examples above take all applicable displacements into consideration\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSafety Notice\u003c\/strong\u003e\u003cbr\u003eIt is absolutely essential that the completed subwoofer enclosure is mounted firmly to the vehicle with heavy steel bolts (0.5 in diameter) and large steel washers on both sides of the bolts. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Summary: This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment. This newest generation of W3’s benefits from a whole suite of advanced technologies originally developed for our flagship W7’s.

Customer is responsible for shipping charges and insurance in sending the product to JL AUDIO. For decades, JL Audio has led with the notion that subwoofers are essential and important to any serious audio system. * The W7’s employ a pole vent to remove heat and pressure from the inside of the speaker. Summary: By utilizing space wasted in conventional speakers, this ground-breaking innovation controls the W7's massive excursion without sacrificing precious cone area. JL Audio Subwoofers.

This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.

The W-Cone assembly achieves its rigidity through architectural means, rather than through inherently stiff materials.

This subwoofer driver has been called the “best damn 8-inch subwoofer ever made” for its remarkable performance capabilities and design attributes. The smaller 8-inch JL Audio subwoofers do not play as low as larger diameter models, but they are designed to output cleaner, tighter, and more accurate sound.
