If they have been factory reset that's the 'normal' sound without calibration.
Get an appropriate mic, watch the video and notice the mic positions and (personally) I would set up only two or three standard positions at first. One for Narrow, music listening, and one for Wide TV watching, others dependent on room layout.
You don't sound like a 'switch it on and leave it' type of person so once you are familiar with the process, my guess is you may want to experiment with adjusting the positioning of the 50s and ( to my ears anyway) speakers and associated equipment do change sound over time especially if furniture and furnishings are changed.
Good luck. They are exceptional speakers.
