The DSPeaker 8033S II is perfect for integrating subwoofers in high quality two channel systems. It comes with a mic and automatically adjusts your subwoofer to remove room coloration's that plague all rooms.

A typical listening room resonates in low frequencies. Because of this, even the best subwoofer may not sound as good as it can. 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 subwoofer is placed close to walls or corners of the room.

The Absolute Sound Golden Ear awarded Anti-Mode™ technology eliminates the resonances of the speaker and the room by equalizing both amplitude and time domain responses using very accurate digital signal processing 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 uses regular RCA connectors, which can be found from vast majority of home theater equipment and 2 channel gear. Input to the device is taken from the line level subwoofer output of the (pre-)amplifier. Output is connected to the RCA line level input of the subwoofer.
