The Alesis M1A 520 USBs (bit of a mouthful that one) are a powered pair of monitors that will connect to your computer directly over USB for ultimate ease of use. Handily, they also manage to double as an audio interface for your computer, with two 1/4" jack inputs tucked in round the back of the speakers so that you can record a single stereo source or, indeed, two mono sources. Anyway, back to the speakers themselves.... Alesis have managed to pack in a lot of performance for a speaker at this price point. They sound detailed, punchy and deliver a surprising amount of bass for such a small cabinet. All in all, it seems Alesis have built a loudspeaker which competes with much more costly designs.
These monitors are ideal for someone who has started creating music on their computer or to compliment a budding digital DJs setup. In fact, if you just need a great sounding, great value monitor speaker and don't already have an audio interface then these are what you've been looking for.
