Anti-Mode X4

Regular price$4,250.00


The new DSPeaker Anti-Mode X4™ preamplifier/DAC combines an uncompromising selection of audio electronics with more than a decade of expertise in acoustics and signal processing. It was designed with one purpose in mind: to elevate to a new high what is possible in stereo sound reproduction in the domestic environment.

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.

The Anti-Mode X4 covers a wide variety of use scenarios, ranging from the traditional "2.0" two-speaker configuration to more exotic installations featuring a number of subwoofers with multiple listening seat optimizations. The best cross-over frequency is automatically determined for speakers and subs.

A modern, easy-to-use graphical user interface is provided. Room response graphs can be inspected in full detail without the need to resort to personal computers or other additional equipment. A built-in graphic design tool is included for all types of sound enhancements.
