Sound system for a 3x3m cinema room

[deansplit]

Hi, any advice for a good value sound system for a 3x3m cinema room. I have just bought a BenQ W1070+, looking for a cheap (ish! - in context of the quality of the projector) sound system. The walls aren't sound proofed or anything, this is merely a projector in a dark room.

Thanks for any help.

The room size and shape will be your enemy. Don't be too ambitious and keep things smallish. Maybe an antimode with sub? Room treatment would help.

Was looking/thinking of the PIONEERS-HS100. Too ambitious? What sort or treatment would help, carpeting the walls? Is there a special type?
