Perhaps if you cannot here much difference there is a reflection that over powers the places you have tried . A mirror placed on surfaces should show you if you are accurately finding the reflective points in your room . After i switched to very wide dispersion components i got reflection . (077,2441,harstfield lenses.)
when i used stuff a touch more beamy i did not . (Cat eye 076, 2344) its an ideal time to see if placement benefits your cause the most , then room treat( try the mirror to help guide ) , then position speakers again , you will never be done . This is a forever hobby .
