I want to make the sound "flat". What equipment do I need to
measure it?

You need

a signal source
a calibrated microphone
analytical hardware or software

(snip)

And one more thing - the actual room you intend to use it in.


Generally, that's pretty hard to avoid.

A "flat" speaker may sound terrible in a room due to furnishings,
carpet, or other features. It's not quite as simple as plugging
it all into a computer - you have to fine tweak it along the way.

Agreed.
