Audibility versus volume is dependent on the frequency.

Easy reference here

When you calibrate all of your speakers(including the subwoofer) to 75dB on the meter the receiver is using a tone that is band limited and -30dBFS. Full range speakers usually get something like a 500hz-2000hz signal.....subs get 40-80hz. The reason the tone is -30dBFS is so you can calibrate everything at volume levels that won't be excessive.

After calibration the system should reproduce "reference levels" when the master volume display reads *00*. This assumes there are no limiting factors involved in the audio presentation.

Did you end up selling the empires, or are you going to run all four subs?

Out of curiosity, what size room are you housing these dual 30s?
