If I understand your question/proposal correctly, this is what the Klippel system does when it generates the Estimated In-Room Response...

I beg to differ. Although in the case of the Kii, the processing is both causing the latency and modifying the low end...

The latency is a result of the signal processing necessary to make the time domain response so nearly perfect.

To get a perfect step response would require bass extension to DC. Short of that, you end up with sort of a right triangle shape. The...
