JL Audio CS112G-TW3 #93312 Sealed ProWedge enclosure with one 12″ TW3 subwoofer
JL Audio CS112G-TW3 12” sub enclosure is actually a design marvel. JL nestled their shallow TW3 12” subwoofer into a sealed enclosure that takes up less room than conventional 12″ subwoofer boxes. This sub handles up to 400 watts RMS so it still delivers that fat low end you want, while its 2-ohm impedance makes it a perfect match for a mono amplifier.
JL Audio used their extensive engineering know-how to build a super-thin subwoofer that still offers big performance, compressing the sub’s motor structure without losing the extended excursion you need to deliver big bass. And for you, that means serious performance in a slender package.
While they may have cut the corners on the medium density fiberboard (MDF) enclosure, JL didn’t cut corners on quality. They incorporated their V-Groove construction to ensure rigid box joints that won’t leak air or resonate. Combined with the slim sub, this new design gives you a sturdy sub box that doesn’t take all your cargo space. JL finished off this ProWedge enclosure with a tough polymer grille that protects the entire subwoofer, unique for an enclosed subwoofer design.
V-Groove MDF Construction
This advanced cabinet-building technique uses CNC-machining to create precise panel joints that make enclosure assembly more efficient and exact.
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.
