B&C Speakers 12MH36 12 inch Woofer Cone TWP Waterproof Both Sides Pro Audio Sound System Midbass LF Drivers 3-inch Copper Voice

The B&C Speakers 12MH36 is a robust and precision-engineered 12-inch midbass woofer crafted for professional audio systems that demand high output and reliability. With a power handling capacity of 400 W RMS and 800 W peak, this driver is built to deliver powerful sound with minimal distortion, thanks to its aluminum demodulating ring and high sensitivity of 101 dB. Its 76 mm copper voice coil, wound on a glass fibre former, ensures efficient thermal management and consistent performance across a wide frequency range of 50 Hz to 3000 Hz. Structurally, the woofer features a double roll surround and radial cone shape, enhancing stability and acoustic control. The ferrite magnet, T-pole design, and single spider suspension contribute to its mechanical integrity, while the TWP waterproof cone treatment on both sides makes it ideal for use in demanding environments, including outdoor and touring setups. From a technical standpoint, the 12MH36 boasts a resonance frequency of 53 Hz, DC resistance of 5.2 ohms, and motor force factor of 22.3 Tm, all contributing to its low distortion and high efficiency (4.8%). It supports 5.0 mm linear excursion and 7.0 mm mechanical limit, with a moving mass of 54 g and inductance of 0.83 mH, making it well-suited for vented enclosures, as indicated by its EBP of 265 Hz. In terms of installation and logistics, the woofer has an overall diameter of 316 mm, a depth of 133 mm, and fits into a 282 mm baffle cutout with a 296 mm bolt circle. It occupies 3.3 dm (0.12 ft) of air volume and weighs 7.6 kg, with a shipping weight of 8.5 kg, securely packaged in a 360 360 200 mm box. Altogether, the B&C 12MH36 stands out as a high-performance, durable, and versatile component trusted by audio professionals worldwide.
