Here's an idea: FRFR auto response correction.
We all know by now that "Flat Response" is far from being what most, if not all, "FRFR" speakers really produce. So why not use a process similar to profiling for generating an auto correction EQ for FRFR speakers? It could be as easy as:
1. Select your microphone (from a list of the most common ones like SM57, SM58, etc)
2. Point it at your FRFR speaker from your standing position at ear level
3. Press a button on the KPA and let it do its magic
And voilá! *real* FRFR response from *any* speaker
