A typical listening room resonates at low frequencies. Because of this, even the best subwoofer may not sound good enough. Much of the audio content get masked by the resonances, introducing unwanted characteristics such as “slowness” and “boominess” to the sound. This problem is most pronounced when a subwoofer is placed close to the walls or corners of the room.

DSPeaker’s Golden Ear awarded Anti-Mode™ technology eliminates the resonances of the speaker and the room by equalising both amplitude and time domain responses using accurate digital filter structures and anti-phasing technology. This way, the listener can hear frequencies down to the cut-off frequency of the subwoofer. Transient response is also drastically improved in the process, making bass sound faster and more controlled.

Anti-Mode 8033 is very simple to use. The calibration process is completely automatic. It generates frequency sweeps to the desired calibration point (or multiple points) and measures the combined transfer function of the subwoofer / room system. 

Anti-Mode 8033 utilises regular RCA connectors, which can be found on the vast majority of home audio equipment. Input to the device is taken from the line level subwoofer output of the preamplifier. Output is connected to the line level input of the subwoofer.
