Query: Very impressive. Big sound from a small system

I was uncertain at first if the quality of sound from this small system would do the XM radio justice. I was very impressed after I hooked up the system and heard the quality sound radiate from the Altec system.I decided on Altec due to its size (bigger Boomboxes are available but space hogs). Its stylish design fits nicely on my bookshelf and it's clean design goes well with any decor.One thing purchasers need to be aware of is that the antenna needs to be placed close..really close, to a window to receive the satellite signal. I have'nt found anything negative to say about this system, well done Altec Lansing. I'm giving it 4 stars simply for the fact I would have liked to seen more user controls on the system.
