DSPeaker Anti-Mode 8033 Automatic Subwoofer Equalizer

A typical listening room resonates at low frequencies. For this reason, even the best subwoofer cannot sound good enough. A large part of the audio content is masked by resonances, introducing unwanted characteristics (such as "sluggishness" and "boominess") to the sound. This problem is particularly pronounced when the subwoofer is placed close to the walls or in the corners of the room.

GoldenEar's award-winning Anti-Mode™ technology eliminates speaker and room resonances by equalizing both the amplitude and time-domain responses using highly precise digital signal processing filter structures and anti-phasing technology. This allows the listener to hear frequencies down to the subwoofer's crossover point. Transient response is also dramatically improved, making the bass sound faster and more controlled.

The Anti-Mode™ 8033 is very easy to use. The calibration process is fully automatic: it generates frequency sweeps to the desired calibration point (or multiple points) and measures the combined transfer function of the subwoofer-room system.

The Anti-Mode™ 8033 uses standard RCA connections, as found on the vast majority of home theater equipment. The device's input is taken from the line-level subwoofer output of the (pre)amplifier. The output is connected to the line-level input of the subwoofer.
