Query: Great small, portable speaker system

This is perfect as an affordable, small, iPod speaker system. A previous review noted a muffled sound -- I noticed at a low volume it does seem a little bass-heavy, but using the remote you can easily adjust the treble and the bass so that problem was easily fixed. Other than that, it's not very feature heavy, but it does what it's supposed to, and it sounds well and is much louder than I expected.
