Would be sweet if it could use the microphone to auto-tune the speakers by playing audio and listening to the result. Microphones are not perfect but a cheap microphone has much better frequency response than cheap speakers. If you assume the microphone is perfect you will get a pretty good result, probably better than a generic "laptop speaker" preset would be.

Omnidirectional electret mics are nearly dead flat right out of the box, and cheap.

You need an omnidirectional mic.
