Yes, I know, it's all the wrong way round! But this is what I have to do, the room is primarily a living room, it is part of the B+B guest space at times, so I need to work around it. First and foremost, how much space should I have behind speakers for them to work well, and how much should I not have them backed into a corner? Which speakers will be the most forgiving of being backed up to a wall, or near a wall, or into a corner? You will be getting the idea by now that I'm not free to stand the speakers very far from the walls! The AV unit is a Marantz SR6009, the speakers are yet to be chosen, the focus is musicality. The room is acoustically neutral, about 5m wide x 4m deep x 2m high. I'm thinking a 4.1 or 5.1 set up, I really don't have space for any more channels, and I'm thinking of up to £1500 budget for the speaker array. I know purists will tell me to stick with stereo kit for music, but I do love the extra depth that surround sound gives stereo music, which is why I'm using an AV unit rather than a stereo amp. Given this, does the advice to use identical speakers on all channels hold, or should emphasis be placed on the fronts?
