AD-21NW151 – 21” Neodymium Subwoofer for Extreme Power

The AD-21NW151 – 21” Neodymium Subwoofer for Extreme Power for professional audio systems that demand deep bass, high power, and uncompromising performance. Whether you’re outfitting a touring rig, a large venue, or a custom sound system, this driver delivers exceptional clarity, power, and durability with every note.

At the heart of the AD-21NW151 lies a 152mm (6-inch) In/Out voice coil, engineered to handle extreme heat and continuous high-power usage. With a massive power handling capacity of 6000W (continuous max) and 3000W RMS, this subwoofer is built to perform at the highest level, even in the most demanding environments.

Delivering a sensitivity of 97 ± 2dB, the AD-21NW151 offers powerful output with reduced energy consumption—making it an efficient choice for systems that prioritize both performance and power management. Its frequency response range of 30Hz to 1500Hz ensures that it covers the deepest lows and essential low-mid frequencies with precision and authority.

The driver features a lightweight yet robust Neodymium N45 magnet (145×60×15mm), which provides a strong magnetic field while keeping the overall weight lower than traditional ferrite-based alternatives. This results in better heat dissipation and enhanced transducer efficiency, especially in portable or flyable sound systems.

The aluminium basket adds structural integrity and helps manage thermal buildup, ensuring long-term reliability under pressure. Weighing just 21.2 kg, the AD-21NW151 balances power with portability, making it ideal for both touring and fixed installations.

Whether used in subwoofer enclosures, line arrays, or high-output PA systems, the AD-21NW151 offers the professional-grade performance needed for concerts, festivals, clubs, or cinema setups. Its low-frequency accuracy and superior power handling ensure a tight, thunderous bass response that enhances the full audio experience.
