Hi all I dont seem to be able to purchase the 5.1 set anymore! I understand that you can use the 6.1 package as a 5.1 setup. I would like to know the maximum distance the 2 rear suround speakers can be apart? If Ive got to buy the 6.1 package I would like to use it but Im restricted to wall mounting the speakers coz I have a 2year old son ! Im really only going for this package coz of its style and its in my price range <£500! if anyone knows of any packages similar let me know.
