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.

DSPeaker Anti-Mode™ X4 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 allow your loudspeakers to truly shine — in your home, in your unique acoustic environment.

The idea of the industry-leading automated Anti-Mode room calibration is simple: to make the loudspeakers and subwoofers work together with the room, instead of clashing against it. The benefits of the Anti-Mode correction include vastly improved clarity, tighter and deeper bass reproduction, the absence of unwanted "boominess", and a seamless integration of the main speakers and subwoofers.

The installation procedure is automated. Anyone can achieve superb results without any prior expertise or knowledge. After a brief calibration process Anti-Mode™ knows your listening space in great detail and designs custom filters tuned for your unique space. You may be very surprised to hear what your loudspeakers are truly capable of!

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.

In addition to the automatic correction, the user has full reign over extensive tone controls and custom filters. The preferred sound signature can be altered even in real-time, from the convenience of your listening seat. Different settings can be stored in memory for a quick recall at any time. Most functions can be accessed with the supplied full-aluminum remote or using the control wheel located at the front panel.

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.

Three high-end stereo digital-to-analog converters (DACs) are driving the primary, auxiliary, and headphone outputs. Combined with output range control and picking the best converters using an IC tester, the XLR outputs reach 126 dB dynamic range and less than 0.0008% total harmonic distortion. Both primary and auxiliary outputs are active simultaneously for speakers and subs, available in both XLR and RCA. The signal of the primary output is also provided as optical and coaxial SPDIF.

The headphone output is available for night-time listening and when you don’t want to disturb your household or neighbors. Headphone mode features a proprietary auralization technique which can make many recordings sound more natural and reduce listening fatigue.
