i am after a home cinema system but i dont know which one is best for me. i either want a 5.1 system with wireless back speakers or a 2.1 system. my room is 21ft long but only 11ft wide. can anyone recommend any and are the 2.1 systems any good. i have listened to the bose 3.2.1 and the sony dav-x10 in a shop and they sound good to me, but i have never had a cinema system before.
