How does subwoofer integration work?

There are four aspects to the DEQX approach to subwoofer integration:

1. Nearfield correction of subwoofer response
2. In-room measurement of the subwoofer(s) and parametric EQ correction
3. Timing measurement to correctly set the delay between the subwoofer and speakers
4. Steep slopes to minimize localization and interaction.

It’s not rocket science but it works remarkable well, when done well.
