I'm thinking of buying the Mission Cinema 70 surround speaker package from Richer Sounds (702e floor-standing front speakers, 70DS and 70C1 centre and rears) , to go with my fledgling Home cinema system. However, my room is small (in home cinema terms) at only 3.5*3.5 metres. So I'm worried these large speakers will swamp the room and make my movies sound dreadful. What does anyone reckon? Are there any better options for under £350?
