the characteristics of your listening room, by using advanced DSP technology and latest psychoacoustic know-how. |

| Reduce the disturbing acoustic characteristics of your listening room without expensive renovations
with simple, self-calibrating DSPeaker products  | DSPeaker Anti-Mode 8033
Unparalleled Efficiency and Ease of Use
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.
