Welcome....what's the rest of your system (RP)? Did the sales guy give you the speakers you paid for? Are they installed yet? Two in-wall and four atmos speakers amongst a complete RP home theater system might sound fine. But.....it is usually recommended to keep them all the same. Depends on the cost and if it's a hassle, might hardly notice any difference.
Picked a great estate sale in WPB mostly vintage jazz and classical recordings
and a few rock records including this Allmans lp on the Bold label out of FL which
i am currently listing to. Interesting version of Mellisa.
