Optimize your stereo system with Anti-Mode 2.0 Dual Core

Speaker-room interaction is typically the most important performance-limiting factor of any high-end audio system. Every listening space introduces errors that can be in the magnitude of dozen decibels or even more. These errors are most pronounced at the bass and lower midrange regions, where the classic acoustic treatment loses its effectiveness.

Anti-Mode 2.0 Dual Core is DSPeaker's award-winning loudspeaker optimization system capable of perfecting the acoustic performance of any full-range stereo audio system. It is based on our new Anti-Mode 2.0 algorithm which refines the popular Anti-Mode algorithm even further.

Features include:

Anti-Mode 2.0 Dual Core can be connected to almost every audio system. Please see the connection example page for more information.
