AD-21SW152 – 21″ Neodymium Subwoofer Driver with 6400W 

Engineered for professionals who demand exceptional low-frequency performance, the AD-21SW152 – 21″ Neodymium Subwoofer Driver with 6400W 21-inch subwoofer designed to deliver earth-shaking bass with clarity, control, and efficiency. With a continuous maximum power rating of 6400W and RMS power handling of 3200W, this driver is built for extreme SPL applications in large-scale sound reinforcement systems, concert setups, and premium touring rigs.

At the core of the AD-21SW152 is a 152mm (6-inch) In/Out voice coil, built to withstand intense thermal loads. It ensures clear, distortion-free sound even during long, high-output sessions.

The large voice coil pairs with a neodymium N45 magnet (150×50×15 mm) to deliver a strong magnetic flux. This combination enhances driver efficiency and performance. Despite its power, the unit remains lightweight—making it a portable solution for mobile PA systems.

It also aids in efficient heat dissipation, which helps protect internal components during continuous, high-output sessions. Despite its powerful performance, the AD-21SW152 weighs only 15.2 kg, making it a lightweight and reliable choice for demanding live shows and fixed installations alike.

With a sensitivity rating of 98 ± 2dB, the driver ensures high output levels with minimal amplifier strain. Its 8-ohm nominal impedance and 5.3-ohm DC resistance offer broad compatibility with industry-standard amplifiers and crossover networks, giving sound engineers the flexibility they need in complex configurations.

The AD-21SW152 features a robust aluminium basket that enhances structural integrity and supports long-term durability. It also helps dissipate heat efficiently, which protects internal components during high-output operation.
