Hi, I'll soon be buying a pair of Epos stand-mounters for stereo use and also for the main channels in surround. I'm just wondering whether anybody with experience of the above speakers can tell me which would be better? I think the original M12 has been around a while now, but I can find a used pair for around £250. Or I can go for a new pair of M5s which I can get for around £310. I know the current M12.2 speaker is a step above the M5, but would just like to know if the original M12 is up to scratch? Also, would the M12 work as well in a small room? This is the reason I am changing to a stand-mount design. Thanks for any help.
