Yeah think thats what i'll go for, with the centre recessed and L&R either side of the chimney wall, now to decide t101's or t301's either side of the tv and 101c or 301c? As the 301's are more expensive might start off with a 3.1 system and move to a 5.1 later when funds allow.
Also the sofa will be right against the back wall, what would be the best option for rears if i do go for a 5.1 system
MA Radius 225 would work too like in the picture, so using three of those like those M&K MP7. If you lean toward T-serie then 301 as mains and 301c as center! Don´t go with the smaller model for the LCR, this is important!
Mount the T101 surrounds little bit higher to get them further away from ears. It´s tricky but not much you can do..
