So I upgraded my home theater system I upgraded from a denon 2400h with 2 r-26f towers with a r-25c center channel and r-15m and 2 rp-140sa and r-12sw. I upgraded to a denon 4500h with 2 rp-280f and a rp-450c my question Is can I use my r-26f towers as rear surrounds with my rp-280f as my front stage? Since I all ready have them. But don't know how it will sound with mixing reference with reference premier lines. Any input would be great thanks I should have all my speakers by Friday.
