Extreme output. Intelligent control.

The Waveshaper W221A combines dual 21″ transducers, Powersoft IPAL amplification and real-time DSP control to deliver maximum acoustic performance through intelligent control.

Waveshaper technology shapes the electrical and acoustic waveform in real time. Differential pressure sensing continuously monitors the transducers, allowing an ultra-low-latency control loop to dynamically optimize the amplifier signal according to the actual behavior of the system.

The result is extreme low-frequency output with precise control of cone excursion, improved efficiency and consistent performance under demanding conditions. Large-area bass-reflex ports minimize air velocity and compression, while integrated sliding and stacking rails support fast, secure deployment.

Powersoft IPAL closed-loop control with real-time differential pressure feedback.
Dual high-excursion 21″ transducers for extreme low-frequency output.
Dedicated amplification: up to 8,500 W per channel, approximately 17 kW total.
Ultra-low-latency DSP optimizes amplifier output and controls cone excursion.
Large bass-reflex ports reduce air velocity and compression while reinforcing the enclosure.
Four DSP presets, including Cardioid for multi-unit setups. Touring enclosure with sliding and stacking rails.
