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

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

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.
