JBL MS-10SD4 Slim

The JBL MS-10SD4 SLIM subwoofer is a 10-inch (250-millimeter), high-performance car audio subwoofer. It has minimal installation depth – just 2-3/8 inches (60 millimeters). Its dual 4-ohm voice-coil design permits a variety of connection options. Its advanced components include a reinforced flat-piston polypropylene cone, progressive spider, dual-roll fabric surround and nonmagnetic, cast-aluminum frame. Power handling of 500 watts RMS (1,000 watts peak) makes this subwoofer an excellent choice for virtually any system configuration.

Shallow Mounting Depth

The MS-10SD4 SLIM subwoofer requires just 2-3/8 inches (60 millimeters) of installation depth, little more than the height of a credit card. This minimal installation depth vastly increases the number of places where you can install one or more this sub. Under seats, in rear-seat or trunk side panels (with custom enclosures), or behind a truck seat against a cab wall – wherever you want to put this subwoofer, it requires very thin installation depth.

Flat-Piston Polypropylene Cone

A subwoofer cone is a diaphragm of a piston that moves air. JBL engineers reconfigured a traditional conical diaphragm as flat, rigid polypropylene material that fits in the compact MS-10SD4 SLIM subwoofer chassis and has a lightweight and stiff composition. The result is an effective low-frequency diaphragm that reduces unwanted mechanical distortion under movements up to its linear-excursion (Xmax) limits.

Dual-Roll Laminated Fabric Surround

A dual-roll laminated composite surround in the MS-10SD4 SLIM subwoofer offers a low profile and tremendous UV (ultraviolet) resistance. Its polyurethane/fabric blend exerts additional restoring force on the cone at high excursion, making its low-distortion bass even better.

Progressive Spider

Like its surround, the MS-10SD4 SLIM’s progressive spider allows progressively more resistive force as the cone reaches higher excursion. It also helps to keep the voice coil centered in the magnetic gap during the delivery of the important bass notes.

High-Q, Wide-Range Sub-Bass Performance

JBL engineers went off the charts for this revolutionary high-Q design with a very low compliance (Vas) to offer extremely effective bass performance in a small space. The low, easily moving compliance of the suspension, combined with the innovative surround and progressive spider to control cone movement as excursion is increased, gives the MS-10SD4 SLIM subwoofer unique mechanical attributes that revise conventional subwoofer thinking.

Small Sealed And Vented Enclosure Volumes

The MS-10SD4 SLIM subwoofer provides amazing bass from a modest enclosure volume. We recommend just 0.5 cubic feet (14,161 cubic centimeters) for sealed designs and 1.0 cubic feet (28,321 cubic centimeters) for vented designs. Vented enclosures provide greater output than sealed enclosures given the same power, so the vented enclosure will work with smaller amplifiers.

The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.
