Automatic Room & Speaker Optimizer

Anti-Mode X2 & X2D


Compact but extremely powerful room correction unit with
remote-controlled preamp.
Features a next-generation
Anti-Mode™ correction algorithm.


  • Connect up to 3+1 digital and analog audio sources

  • Supports stereo systems with an optional subwoofer

  • Anti-Mode™ 3 algorithm

  • USB type C connector for audio input

  • Very small size, fits anywhere

  • Plug and play: no expertise required to calibrate and use

  • Available in two variants *:

    • X2 with analog stereo output for an amplifier or powered speakers

    • X2D with digital outputs (optical & coaxial S/PDIF) for external DACs

*) both variants feature an analog output for a subwoofer

The latest addition to the DSPeaker product family, the Anti-Mode™ X2, is a versatile DSP powerhouse. It features an all new Anti-Mode 3 algorithm which will automatically optimize the combination of main speakers and an optional subwoofer with the acoustic environment.

A fully customizable tone control functionality is available, in addition to a state of the art digital crossover and a subsonic filter. Most of the functionality is adjustable in real time using the supplied sturdy remote controller. Multiple sound profiles are supported that allow quick access to previously stored sonic configurations.


Anti-Mode X2 is the perfect sound upgrade to any stereo home audio system. Add it as a processor to your existing set-up, or use it as a preamplifier and build your home theater around it!

Anti-Mode X2D replaces the analog stereo output with a S/PDIF digital stereo output in coaxial and optical Toslink formats, but keeps the analog subwoofer output for the 2.1 speakers + subwoofer configuration. This makes it possible to use an external DAC for the main channels.
