Cool, but 1 minor hitch.
It doesn't 'fix' the room.
It corrects the bass at 1 location. If you are primarily a solo listener this is a terrific way to go. If you need to cover more area, than other systems which measure several points and provide an average correction may be more desirable.
Bass. Can't live with it. Can't live without it.

This was sent to me by email from Tweek Geek. I have no idea who else might sell the unit or their pricing.


"Average correction", leo? You prefer grading on the curve?

For the single location listener, this bass correction device is pretty hot. The sweet spot will only be so large. For persons who need a larger sweet spot, one of the systems which take multiple measurements and 'average' them may work better.
It is even possible that in making the bass better at your listening spot, you make it worse somewhere else....as if that mattered to the single listener.

Are you and I reading the same page, leo?

"Ease of Use
The 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.


Compensating for Room Modes with the Anti-Mode
The calibration program self-generates sweep-like measurement signals and picks up the data with included microphone. The process will autonomically define parameters of the room modes ... This will eventually lead to the designs of custom-fitted Anti-Modal Filters, AMFs. Up to 24 distinct AMFs can be designed, although far less are usually ever needed for one position. The extra AMFs give the algorithm more freedom when extending the effective area of the compensation for more globally improved results.

Just went to there site and had a quick look.
Indeed....multiple points!
Now, the sweet spot can be quite a bit larger.
If I had 300$+ to 'test' I'd be tempted. My irregularly shaped room would be a nice challenge with good payoff.
Did the back panel have 0degree and 180degree outputs?

The online literature claims the unit distinguishes itself by also making multiple corrections for phase and time anomalies.

I know nothing about this unit, leo, what I read is what you can read. I just thought this might be an interesting addition to this portion of the forum since someone might find this unit useful. I can neither endorse nor denouce this unit since I have no hands on experience with it.

If it works as advertised, it's a pretty good deal, especially if someone wants to move furnishings a lot.
