JL Audio CP208LG-W3V3 Loaded Sub Enclosure
Enclosed Subwoofer System with Dual 8W3v3-4 Subwoofer Drivers, Black Carpet (500 W, 2 Ω) – Ported Enclosure
This incredible MicroSub™ JL Audio CP208LG-W3V3 loaded subwoofer enclosure system delivers the kind of output and extension that is normally possible with only much larger systems. The key to its performance lies in the precise tuning of its dual 8W3v3 subwoofer drivers, each in separate airspace, with an efficient slot-ported design.
Extensive interior bracing permits the use of thinner wall material that maximizes the enclosure’s internal volume relative to its exterior volume. The port for each driver wraps around two walls of the enclosure to produce the necessary low tuning frequency that ensures excellent extension and response smoothness. The two flared port entries/exits, one on each end of the enclosure, further enhance sound quality by minimizing air-flow noises through these ports.
This JL Audio CP208LG-W3V3 subwoofer system is shipped wired, loaded and ready to connect via a five-way binding post terminal.
Finish: Black, high-grade automotive carpet with silver “JL AUDIO” embroidery on front baffle. Steel mesh grilles are included to protect the subwoofer drivers.
Flared Slot Port
While ported enclosures deliver important efficiency advantages over their sealed counterparts, they also present unique design challenges. In car audio, the desire for lower tuning frequencies from small enclosure volumes leads to long port lengths that often require compromising the port area. These compromises lead to higher airflow speeds through the port, which can create noise as the air is driven across the edge of the port. The flared port design minimizes these airflow effects by providing a smooth transition for the high-speed air flow, rather than an abrupt termination. The result is less noise and cleaner-sounding bass.
With the JL Audio CP208LG-W3V3 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.
