About the Anti-Mode 8033

The DSPeaker Anti-Mode 8033 is a single-channel audio processor designed to correct subwoofer bass response in home theater and stereo systems. It eliminates bass-masking standing waves and room resonances by equalizing both amplitude and time domain responses using precise digital filter structures and anti-phasing technology. The device features fully automatic calibration—simply place the included measurement microphone at your listening position and press a button to generate frequency sweeps that measure the combined transfer function of the subwoofer and room. The Anti-Mode 8033 then creates custom digital filters to correct the response, resulting in faster, punchier, and more controlled bass that extends down to the subwoofer's cutoff frequency. Installation is straightforward, connecting between a preamplifier's subwoofer output and the subwoofer's line input via standard RCA connectors. The device has received critical acclaim for delivering exceptional improvements in bass precision and definition at an affordable price point.
