One of the things anyone who purchases a home theatre systems should do it optimise the speaker outputs (if the system allows this). Doing this requires the use of a sound-pressure-level meter.
Optimising your speakers will make a significant difference to the sound of your system and give you the best quality sound.
Many systems emit a series of test tones you can use along with the meter to do this. It’s well worth the effort.
