It is exactly 10dB higher for the in-band frequencies (40Hz-120Hz for cinema, pink noise)

An easy way to do this is measure the level of the band-limited pink noise of 40Hz-120Hz on your left speaker.
Then measure the LFE channel -- it should be 10 db higher for the same band-limited pink noise.

(this is assuming you have good L/C/R that can properly produce down to 40Hz)

Thank you for the quick reply. So have the +10gain on and run the test again but for the LFE have a LP of 120Hz as well?

I have the JBL LSR 4328P x 5 and Sub is LSR 4312P
