Hi there, I'm getting married later in the year and instead of getting a dj in to play The Birdie Song and Raining Men, I thought I'd do a big playlist myself from my Ipod. Has anyone got any advice on the best speakers to use for this purpose. The room for the music is about 30 by 50 foot so its not huge. Would a single unit be good/loud enough you reckon, or would I need some 'proper' speakers. Any help much appreciated.
