Right, I'm narrowing my choices down after much work time used reading opinions here. I have a Kenwood 5050 amp, and a pair of Mordaunt Short MS3.10 3 series which I'm gonna use for my fronts. I'm looking at either the mission 77ds or Mordaunt short MSB20 bipolar for the rears (which I'm going to have to put on the back wall just behind and to the side of the sofa). Which is better for this? (I'm leaning towards the missions, but not sure if it's better to stick to one manufacturer.) Also looking a the Mordaunt short MS 905C for the centre. Will this be compatible with my fronts, or are they just too old to match? Can anyone help, PLEASE. I've got a credit card burning a hole in my pocket.
