"So, to sum up; It's small enough to tuck out of the way, sturdy, simple for technophobes, effective enough for technophiles, as cheap as it currently gets and it works. That makes it an easy recommended buy."

Stereophile, April 2009

Anti-Mode 8033 is selected to Recommended components listings under Signal Processors category in the special issue of wth "500 recommended components". In addition the 8033 received rare "$$$" marking for it's exceptional price/quality rating.

"Where we have found a product to perform much better than might be expected from its price, we have drawn attention to it with "$$$" next to its listing."

Stereophile January 2009, "Music in the round by Kalman Rubinson"

"When I restored the 8033's EQ, each pedal tone became distinguishable. There was similar salutary effect with low percussion and winds, and, of course with film sound effects"

"In summary, the DSPeaker Anti-Mode is a dandy little device for taking care of the major influences of room modes. It is incredibly easy to use and reasonably priced"

HI-FI World August/2008

"Bass rhythms became tighter and unwanted 'thump' was lessened, making the bass more fluid and natural"

"Calibrated subwoofer sounded clearly more balanced and accurate. Also the integration to the main speakers improved, and localization of the subwoofer diminished"

"Anyone can use it, and the result is always consistently successful"

Hifimaailma 2/2008 (in Finnish), Automatic calibration systems review (Audyssey, MCACC & YPAO)

"For example the Anti-Mode 8033 tested in previous issue, was compared to these systems completely superior tool for adjusting the subwoofer"

Anti-Mode 8033 Automatic Subwoofer Equalizer

A typical listening room resonates in low frequencies. Because of this, even the best subwoofer may not sound good enough. Much of the frequency 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.

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. Input to the device is taken from the line level subwoofer output of the (pre-)amplifier. Output is connected to the line level input of the subwoofer.

  • Measures combined frequency response of the speaker and the room
  • Measurement microphone is included

Connecting 8033 to stereo pre-out or speaker-outs

DSPeaker stereo to mono cable for 8033 (sold separately)
DSPeaker speaker-level stereo to mono RCA for 8033 (sold separately)

Connecting Anti-Mode™ 8033 to stereo pre-out is now easy and simple.  While ordinary Y-cable is not suitable for signal summation, the new accessory sums two RCA signals (stereo) to one (mono) signal that can be used with 8033.

A special high-to-low-level adapter is now also available, which enables connecting 8033 directly to a stereo speaker-level output.

Car power adapter (accessory)

Car adapter for Anti-Mode™ 8033 enables the Anti-Mode 8033 device to be used with Car Hi-Fi systems. Adapter has been designed for standard 12V systems. Standby current 5mA in room temperature.
