Query: pretty good

This is a pretty good shelf unit. it's TINY - kinda like 3 rubic cubes in a row.the subwoffer makes the sound much better.the L & R speakers are good sound quality, but not great.the Ipod adapter is a little funky when you plug it in, it sort of fast forwards your song, and displays some interface message.you start the song over and it's fine. otherwise it plays great.good value for the money, good for a small room or kids, but if you want really good sound, or have a big area, you may want something different.
