Its motor is optimized by JL Audio’s Dynamic Motor Analysis (DMA) technology, reducing distortion and improving transient response, producing clear and articulate bass. With a 4-inch voice coil and a linear excursion (Xmax) of 18.5 mm (0.73 inches), it ensures high output and efficient power handling. Sensitivity is 86.7 dB SPL (1 W \/ 1 m), with a free-air resonance (Fs) of 35.34 Hz.\n\u003c\/p\u003e\n\n\u003ch3\u003eMarine construction and durability\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eM7-12IB-S-GmTi-4\u003c\/strong\u003e is built to withstand saltwater marine environments. It features UV inhibitors, corrosion-resistant polymer baskets, marine-grade synthetic spider suspensions, and gold-plated brass binding posts.
