Reference-Level Bass for Any System

Powered by Class H digital amplification and featuring an advanced 56-bit DSP, DN12 plays exceptionally impactful bass down to 25Hz.

Loud & Clear

DN12’s unique 3XR™ Architecture ensures that it plays louder and lower than ported subs without unwanted port noise distortion.

Blends Beautifully

Intelligent Phase Control™ provides 360 degrees of tuning, ensuring your bass blends perfectly with the rest of your system.

Custom Class H Digital Amplification

The advanced, ultra-efficient 1500W peak Class H digital amplifier delivers continuous power to cleanly reproduce sustained bass down to 25Hz. With real-time monitoring and adjustments to the sliding rail voltage, the DN12 delivers considerably higher power during short, transient peaks such as bass drum kicks and on-screen artillery blasts.

With three built-in performance EQ modes (Flat, Deep, and Loud), the Descend DN12 can be optimized to your room and listening preferences, and adjusted to match whatever you’re listening to.
