Hi all, am now in my new house with a great size lounge. Have arranged my naim audio system for my hifi and the PJ is being installled this weekend after the room is painted and the wires channeled into the walls. Going to try for 7.1 with two MandK K5s for the rear centres. Have asked before about rear di/tripoles. Thought M and K were the only make of these but am told b and w do them too. Should I look at tonally balancing bearing in mind I already have naim mains and a ruark centre. Also and more importantly, if I do away with the 7.1 idea and put the settee on the back wall, do I still want tripole/dipole speakers or do they need a distance of wall between them and the wall of the room as I can imagine one of the mids firing straight at the wall. and finally (sorry) the room is now fairly big, and the house is costing me more than I expected (as ever), will the K4s (£500) be good enough in terms of room filling ability or should I look to the one step up at £800 unles someone can suggest a cheaper place or an alternative from another manufacturer. Thanks as ever.
