Hi, I'm looking to purchase a new system for my classroom (approx size 4m by 8m). I have a large Interactive Whiteboard and a projector (not a specific cinema projector) and use my laptop as a dvd player. I cannot decide to go for something like an all in one system stright out of the box or to purchase seperates. I run a film club once a week and at the moment we have 2 tiny speakers and no sub woofer. I would need the system to connect to my laptop so that i can play music and internet clips and assuemd this would not be a problem if i use the hdmi connection on the computer. My main problem was that when i looked at the all in one systems the speakers seemed fairly small and i was concered that the sound maybe lack a bit of base. I know this is probably an unusal request for help but kind of assuemd it might be like getting a system for a large front room. Any advice you can provide would be grately appreciated.
