I have a strange set-up request. Our work is about to purchase a Promethean Whiteboard (those interactive things they have in schools these days), which is driven by a computer sat in the corner, and hooked up to a projector, which projects onto the whiteboard, and then you can control the presentation by touching the whiteboard.
What I need to find is a set of speakers (at least 2, but a surround sound setup of about 4 speakers (Sub optional)) that can be mounted on the wall. The room is about 30 metres x 15 metres. I am interested in knowing if I need computer speakers, or normal hi-fi style speakers (I think computer sized speakers would look odd mounted on the wall.)
The budget would be as little as possible, but not to exceed $500, as we are a charity. This would include a soundcard if needed, as we use Realtek on-board sound in the computer I imagine will be used to drive the system.
Any advice on purchases would be greatly appreciated, and any general advice too.
