Re: System advantages/disadvantages
I think these discussions are on topic, headroom requirements for different musical and mix styles and levels are huge. For instance, when we used to provide sound for Prince, with Rob Colby mixing we would bring in double the LF of our usual systems which matched LF drivers one to one with low mid drivers, while his previous (deaf) engineer used our normal set up and clipped the high mids!
The levels you currently mix at (not unusual for young audiences for the last three decades) require a system with ten times the output power as would be required for the levels I typically mix at covering mixed age audiences.
The low frequency response you prefer requires about double the LF drivers and amps as what seems typical of most systems I see in use.
Albums played back through a system with a "haystack" LF response will of course be LF heavy. Looking at the response of the recording in the spectrograph or RTA in Smaart will tell what it looks like without the boost. Don't confuse average with peak, even if the LF looks 10-16 dB louder on average, if there are any mid or high peaks within 6 dB of the LF peaks, a system would require only a 6 dB difference in output potential to reproduce them, not 16.
Measuring the spectra of music typical of the artists you work with is a good starting place to determine what system expansion route is appropriate. Not all genres require tons of bass, but if they do, don't leave home without it :^).
