AD-12X403M – Powerful 12-Inch 400W RMS

The AD-12X403M – Powerful 12-Inch 400W RMS  is a premium-grade 12-inch professional woofer, crafted to deliver maximum power, clean sound, and long-term reliability in demanding audio environments. With advanced engineering and durable components, this woofer is ideal for high-performance PA systems, live stage setups, bass cabinets, and full-range enclosures that require consistent output and clarity.

Engineered for power, the AD-12X403M boasts an impressive 400W RMS power rating and can handle up to 800W peak power, ensuring exceptional sound pressure levels and punchy audio delivery. At its core is a 3″ (75.8mm) CCAW voice coil, which offers excellent thermal resistance and efficient power transfer. This allows the woofer to maintain sonic accuracy and stability, even during long and loud sessions.

The speaker covers a frequency response of 55Hz to 3000Hz, delivering tight, deep bass and smooth midrange output. Whether you’re pushing low-end bass in DJ setups or building a full-range speaker cabinet, the AD-12X403M ensures a rich and dynamic soundstage.

Its 96 ± 2dB sensitivity makes it highly efficient, reducing the need for high amplifier power to achieve strong output. This feature makes the woofer ideal for setups where performance and energy efficiency matter equally.

The rugged aluminium basket offers strong structural support and improves heat dissipation. This makes the woofer ideal for long hours of use at high power levels. It has a nominal impedance of 8 ohms and a DC resistance of 6.2 ohms. These specifications ensure compatibility with a wide range of amplifiers and crossover systems.
