Space is at a premium as I'm on a motorcycle - anyone know a single amplified cheap speaker I can use for presentations with a macbook air? I do not need stereo - audeio/videos are all voice speech content
How small is too big? How loud does it need to be?
Best option retaining the ability to stuff into a backpack (albeit awkwardly) would be a soundbar of some sort, but price and needs very a lot in that market.
