I have M60's, QSv8's and VP 160 speakers mated to a Emotiva MMC1 and IPS1 amp and processor. The Emotiva has "Side axis" capabilities, between the fronts and rear surrounds. I am wondering if a pair of Mirage in ceiling speakers between the 60's and the 8's would really "open up " the sound. I have a regular living room, 13x18. Any suggestions?
