JBL engineers designed the MS-10SD4 SLIM shallow-mount subwoofer to produce exceptional, precise bass from an amplifier capable of delivering up to 1000 watts of power.
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.
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.
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.
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.
A proprietary cast-aluminum frame on the MS-10SD4 SLIM subwoofer ensures a rigid chassis for the sub’s moving parts. Since cast aluminum is nonmagnetic, more of the sub’s magnetism is focused on the voice coils to control the cone’s rapid, piston-like movement and reproduce even the most complex bass sounds faithfully.
Dual voice coils in MS-10SD4 SLIM subwoofers offer the best range of wiring and system configuration options. Wire the voice coils in series for an 8-ohm load. Wire the voice coils in parallel for a 2-ohm load. When you’re using multiple subwoofers, the dual voice-coil configurations allow dual, triple and even quad subwoofer designs that match perfectly with the optimum amplifier load.
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.
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.
MS-10SD4 SLIM subwoofers feature spring-loaded connection terminals for both voice coils, ensuring ease of connection for a variety of wire-gauge sizes. The sub’s push terminal also makes easy work of connecting series or parallel voice coils, or wiring to other subwoofers.
