Here is a screen shot of the Recording of the Front 2 Channels.

+3dB on all channels.
With LFE Driven 60Hz Full Scale.
All Large vs Rears set Small and Crossover at 150hz.

By the way there is 7.6dB of headroom. If anyone can figure out how that is arrived at I'd love to know.

In theory the signal should be Full Scale +10dB (split among all the large channels).

If you think listening to music is fun, try learning an instrument.
