OP here,
Gosh, I never thought to provoke so many heated comments. Thanks to all who made positive comments and suggestions.
My living room is 14x19, speakers are on the short wall ,about 3 ft out from the wall and 3.5 ft from the side walls, very slightly toed in. I listen about 8 ft back. There are 3 windows with heavy curtains, Carpet over wood floor, no room treatments. Tonal response is good.
the speakers are in phase according to a test record. As to polarity I have no idea how to test individual components and doubt that it can be changed on any component.
Again thanks to those who gave advice.
