I forgot about the subs
Do you have an SPL meter??? ... if you don't, is a good idea to get one, you can calibrate all your speakers to have the same loudness (even if you auto calibrate, you'll use the SPL to check the set up).
To set the subs, you need to set one at a time (here is where you need the SPL) and after you set them; you need to check the response of them together
(If you don't set them right, one will sound louder than the other)
