JL Audio CLS113RGW7AE Enclosed Subwoofer System with Single 13W7AE-D1.5 Subwoofer, Black Carpet (1500 W, Dual 1.5 Ω) - Sealed Enclosure

General Features:

Enclosed Subwoofer System with Single 13W7AE-D1.5 Subwoofer, Black Carpet (1500 W, Dual 1.5 Ω) - Sealed Enclosure

For those who seek the ultimate in compact-enclosure sub-bass fidelity, we offer this sealed ProWedge™ system, in which the superb performance capabilities of the W7AE Subwoofer are harnessed within a compact, sealed enclosure. This system has it all: extension, impact, detail and smooth response... at any listening level.

This enclosure design has been carefully engineered to the optimum sealed enclosure alignment for the 13W7AE-D1.5 and has been fine-tuned through extensive real-world listening.

This subwoofer system is shipped wired, loaded and ready to connect via a five-way binding post terminal.

The angled-back design saves precious cargo space by allowing the enclosure to fit tightly against the back of a vehicle's rear seat.

Finish: Black, high-grade automotive carpet, with gloss-black laminated decorative front baffle trim. Three solid aluminum bars provide stylish and rugged woofer protection.

Construction: CNC-Cut High-Grade MDF

Recommended amplifier power: 500 - 1500W
Nominal Impedance: Dual 1.5 Ω

V-Groove MDF Construction

Summary:
This advanced cabinet-building technique uses CNC-machining to create precise panel joints that make enclosure assembly more efficient and exact.

Detailed Information:
We begin with quality medium-density fiberboard, which is then machined on our CNC-controlled KOMO woodworking stations. These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.

Once the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a "wrap": a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.

The V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures. The quality of the MDF used in JL Audio systems is also vastly better than the typical "China-Grade MDF" used in the imported products.
