Knowing most of the start of the art testing equipment back in the day the amp was more than likely a Phase Linear 700B or possibly a Carver PM1.5 although were more a mid 80's design.
I much prefer a setup done by ear, I don't care what computers/machines say, it's my ears that I have to please. Not some readout.
Things such as YPAO I love as it automatically sets up delays and timings, the rest, I couldn't give two hoots about it.
Like red wine, I don't care what the label or pricetag says, if I like it then it's the best red on the planet.
EDIT My setup is used for 95% music, maybe if I watched many more movies I might have a different outlook regarding software based setup.
I believe you've set the fronts (JBL Pro 4311) to 'LARGE' correct?
If so, and looking at the frequency response of the 4311 monitors as published by JBL Pro, the SPL output drops like a cliff from 50Hz down to almost nothing by 30Hz. My understanding of the full frequency band is 20Hz to 20kHz. The Dolby specs has significant lower frequency range (believe this is around 8 Hz) so unless there is a sub to supplement the last octave and you've enabled bass management by setting the fronts to 'SMALL' on the Yamaha receiver, there's nothing to hear.
I.e. lack of bass.
If you do not have a sub, Yamaha will divert the LFE channel (the 0.1 in 5.1/7.1 soundtracks) to the fronts which are not capable of reproducing those low bass frequencies. For 2.0 channel music things are not that bad, provided certain precautions are taken as noted below.
You might be okay if the volume limits are imposed such that the system wont get too loud. In this case it's a good idea to implement volume control to protect both the speaker from over excursion and prevent the amp section of the receiver to clip or go into thermal protection mode.
Some compression tests at the maximum desired listening volume should be carried out to check if the volume limits have been set correctly.
Then tune the receiver's setting to one's listening tastes.
