18 Sound 12MB720-8 Midbass Driver 500 Watts AES 1000 Watts Peak Compact 2-Way Reflex Enclosures 8-Ohms PRO Audio Car Motorcycle Component Speaker

The 18 SOUND 12MB720-8 is a high-performance midbass driver from Eighteen Sound, known for its sensitivity and power handling capabilities. || Here are some of its key features || • Sensitivity: 100dB 1W/1m, which indicates a high efficiency in converting power into sound. || • Power Handling: 500 watts AES, with the ability to handle up to 1000 watts on a continuous program. || • Voice Coil: 75mm (3") Interleaved Sandwich Voice Coil (ISV) for a linear motor assembly and reduced eccentric behavior when driven hard. || • Frequency Range: 90 - 4000 Hz, suitable for a wide range of midbass applications. || • Cone: Curvilinear paper cone made from high-strength wood pulp, designed for linearity and control of bell-mode resonances. || • Suspension: Multiroll suspension made from a linen-like material, offering resistance to aging and fatigue. || • Demodulating Rings: Single Demodulating Ring (SDR) designed to reduce intermodulation and harmonic distortion and improve transient response. || • Magnet Material: Ferrite, optimized using FEA CAD resources to maximize flux density in the voice coil gap and improve cooling || • An exclusive treatment has been applied to the cone giving it water repellent properties. || • This driver can be used as either a bass/mid driver in compact 2-way reflex enclosures or as a dedicated midrange driver in multi-way touring and fixed installation concert and arena systems. Its design ensures excellent performance and durability, making it a reliable choice for professional audio applications || SPECIFICATIONS || Nominal Impedance : 8 ? || Minimum Impedance : 6.4 ? || Nominal Power Handling : 500 W || Continuous Power Handling : 1000 W || Sensitivity : 100.0 dB || Frequency Range : 90 - 4000 Hz || Voice Coil Diameter : 75 mm (3.0 in) || Winding Material : copper || Winding Depth : 15.0 mm (0.59 in) || Magnetic Gap Depth : 10.0 mm (0.39 in) || DESIGN || Surround Shape : M-roll || Cone Shape : Curvilinear || Magnet Material : Ferrite || Woofer Cone Treatment : Weather protected || Recommended Enclosure : 25.0 dm3 (0.88 ft3) || Recommended Tuning : 60 Hz || MOUNTING AND SHIPPING INFO || Overall Diameter : 310 mm (12.2 in) || Bolt Circle Diameter : 295 mm (11.61 in) || Baffle Cutout Diameter : 283.0 mm (11.14 in) || Depth : 142 mm (5.59 in) || Flange and Gasket Thickness : 13 mm (0.52 in) || Net Weight : 7.8 kg (17.2 lb) || Shipping Weight : 8.3 kg (18.3 lb) ||
