It can be hard deciding on the best home cinema package, every room is different and then there are just so many variants. The very best suppliers will have a demo room with a large range of loud speakers including in-wall types. There should be lots of other types too, say from B&W and Monitor Audio, plus sub/sat systems and standard box speaker designs. Plus of course, different receivers from the likes of Onkyo, Arcam, Pioneer, Denon, Marantz and Yamaha.
