Nevile Thiel (rip) gave me great advice once to counter standing wave problems. To use odd multiples rule.
Position your speakers so the bass driver for best standing wave countering is at 1/3rd of the room length or if this can’t be done 1/5th or 1/7th. Same goes for the width.
Unfortunately floor to ceiling is pot luck.
I have mine which can go down to 20hz -3db at 1/5th length and 1/7th width, and it worked a treat.
Cheers George
