I adjust and move my speakers 2-3 times a week. Different recordings benefit from different setups, so I don’t think there is one right way. Also, am I in the mood for a wide soundstage or feeling close to the singer, with the instruments in the background?
I play with 5 to 7 feet apart 2-3 feet from back wall, toe-in enough that I can see the outside of the speaker walls. Your room size, speakers are vastly different though.
Now setting speakers farther off the wall, what does it do ?
for rear-ported speakers it would reduce the bass, as far as I know
