I would recommend doing this: NOTHING. Adding or presupposing what should be done may be too much. 1) Get used to the sound, which means ample break in. 2) Work with positioning the speakers in the room, contrary to non OB speakers, moving them even 1/2" towards or away from the back wall will affect bass (OB bass gets lighter as you move towards the corners of the room). 3) Once you feel like the speakers are dialed in and you are loving the sound, then just listen! Over time, something may bother you sound wise, THEN, depending on the severity of what you hear and have ruled out speaker position and break in, would be the time to play with room interaction, cables, etc.
In the mean time if you can, watch Dennis Foley's videos on You Tube (Acoustic Fields). He has a wealth of information on why room interaction is paramount.
Have fun!
