I was about to but a pair of Misson 70DS speakers to act as centre rears to go along with my 70DS surrounds. I've just discovered they don't exist any more, so I'm a bit stuck now. Any suggestions? Because of an awkward window, I was going to mount the rear centres very high (few inches below coving) firing downwards (the Missions upside down). I was contemplating raising the surrounds to the same level. If I don't have them that high, I'd have to make do with a single speaker. It is a reasonably large room (20'x19'), and the rest of my kit is: Denon 3803 receiver 2x REL Q200E subs Mission 733i fronts Mission 73C centre Mission 70DS surrounds Once I've sorted out the rear centres it is time to tackle the fronts & centre, as I really feel I need a bit more mid-bass "punch". I'm using a projector, so I'm tempted to get 3 of the same speaker. Thanks in advance for any thoughts.
