Thanks. You are right. One cannot have a 5.1 studio.

In a studio, the ideal could be five matched full-range (25Hz -
25kHz) speakers in a 5 channel 'composition', studio, and, a surround
with LFE if the studio is designed for commercial 5.1 type work.

The situation faced by composers (and studios) who wish to create a
multi-speaker environment is one that appears to have no standardized
response. (Twenty years ago, few ea studios had subwoofers ...).

As a composer setting up (or modifying) a home studio, should I think
of having an amp between the output of my mixer (if I still use one),
and my speakers? If I am using an amp and powered speakers, how does
the volume control function?

If I wish to create a five-channel (n-channel) piece, I would use the
sub as a way of extending the range of my monitoring system.

In doing the mix / distribution, my thinking is that the signals are
full range, but the speakers aren't, therefore a sub-woofer channel
is extracted from the five channels being sent to the monitors.

In concert, we have a stereo source into the splitters, and a feed is
taken from the post-fader AUX sends so that as the overall signal
level changes, so does the amount of signal being sent to the sub(s).

Best
