John, are you sure about the direction of inaccuarcy of the the Radio Shack SPL meter? It actually underestimates the sound level at lower frequencies as evidenced by correction tables. So if the sub is calibrated to 75 dB along with everything else, it will be around 2dB "cold", not "hot", compared to the satellites. I too prefer the bass effects to come as a briskly felt surprise rather than an ever present boominess. The openning battle scene in Master and Commander is one of my favorites for testing the capabilities of the EP-500.
