JL Audio CS112LG-TW3 Single 12TW3 PowerWedge - Sealed

JL Audio CS112LG-TW3

Enclosed Subwoofer System with Single 12TW3-D4 Subwoofer Driver, Black Carpet (400 W, 2 Ω) - Sealed Enclosure
In this low-profile PowerWedge™ subwoofer system, we harness the performance of the 12TW3 to deliver amazing sub-bass from an enclosure that is only 4.5 in. (114 mm) deep. This low-profile enclosure design has been carefully engineered to the optimum sealed enclosure alignment for the 12TW3-D4 and has been fine-tuned through extensive real-world listening. The PowerWedge™ subwoofer system is shipped wired, loaded and ready to connect via a five-way binding post terminal. Finish: Black, high-grade automotive carpet with "JL AUDIO" embroidered in silver on the front baffle. A steel mesh grille is included to protect the subwoofer driver. Construction: CNC-Cut High-Grade MDF Recommended amplifier power: 100 - 400W
Nominal Impedance: 2 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.

Dynamic Motor Analysis - DMA Optimized Motor

Summary:
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. Detailed Information:
Since 1997, JL Audio has been at t
