Welcome to Upgrade-Sound Website!
German Visaton's DIY Loudspeaker Kits offer excellent, test-winning sound quality at very attractive price, and in the design YOU wish. Huge Visaton portfolio More than 500 loudspeakers, kits and accessories	Finnish DSPeaker's products tackle the weakest link of your audio chain: 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.
