Detailed description
Detailed description
The JL Audio M7-12IB-S-GwGw-i-4 marine subwoofer is a 12-inch (300 mm) woofer designed for infinite baffle applications. It features a Transflective™ LED lighting system and comes with a glossy white finish trim ring and sport grille.
Performance and acoustic design
This subwoofer delivers a continuous power handling (RMS) of 600 watts with a nominal impedance of 4 ohms, and operates within a recommended amplifier power range of 200 to 600 watts. Its sensitivity is 86.7 dB (1 W / 1 m). The M7-12IB is optimized for infinite baffle use, requiring a minimal air volume of 3 cubic feet (approximately 85 liters) behind the driver for optimal performance. It is also compatible with large sealed enclosures (minimum 0.056 m³, optimal 0.085 m³) or vented enclosures (0.14 m³).
Marine construction and durability
Designed for the marine environment, this subwoofer features corrosion- and UV-resistant construction. Its cone is made of mica-injected polypropylene with a synthetic rubber surround. The basket is manufactured from a corrosion- and UV-resistant polymer. The suspension system includes a 4-inch voice coil, ensuring a linear excursion of 18.5 mm (Xmax) and high power handling. The connection terminals are gold-plated and marine-grade. The DMA (Dynamic Motor Analysis) technology helps reduce distortion and produce accurate bass.
Integrated LED lighting
The M7-12IB-S-GwGw-i-4 subwoofer is equipped with a Transflective™ RGB LED lighting system that emits diffused light through the speaker cone. The lighting appears silver when off. The LED functionality requires a separate 12 V wiring for each speaker. For adjustable LED control and thousands of color combinations, an RGB controller is required (sold separately). A 750 mA fast inline fuse must be installed on the positive wire of each LED cable to protect the LEDs and speaker from excessive current.
Dimensions and physical specifications
The nominal speaker diameter is 12 inches (300 mm). The cutout diameter is 306 mm (12.0625 inches), and the mounting depth is 202 mm (7.94 inches). The total diameter of the subwoofer is 356 mm (14 inches). Its net weight is 11.5 kg (25.35 lbs). The free-air resonance frequency (Fs) is 35.34 Hz.
