my existing set up is
rti10's frt l/r connected w14g at 6' and bananas
csi3 cen connected w16g at 5' w/bananas
mon50's surr connected w/16 gauge from 28' to 35' w/bananas
mon30's rear surr connected w16g from 28' 32' w.bananas
new epic valor sub not calibrated yet w/spl at 8' w/rca
now i am not completely set up with avia or an spl but i was wondering if i should dump all the mon's and csi3 for a csi5 and rti8's to go 5.1
and whether my sub should have a better cable or my rear speaks for that matter.
the room is 14' by 18' by 8'
driven by an onkyo 605 ( should i get an amp? )
i know there is a lot of info lft out but please advise on any improvements or suggested upgrades
