Input:
User Review: If you live in a dorm or a barracks, this is a nice speaker system to have. The right and left speakers are very small, making it very easy to find a place to put them. Also, the supports for these speakers are made of metal, not cheap plastic.
 The volume control is a problem area, however, which is why I flicked off a whole star. Every time you turn the speakers on you have to adjust the volume according to your needs. There is no visual representation of where you are when it comes to volume.
 One of the selling points of this speaker system is the fact that it is so easy to connect, right out of the box. In a matter of 2 steps I had my speakers hooked up to my Playstation 2, ready to go.
 Until you get your mansion and the money to buy the Nakamichi Soundspace 21, these Altec Lansing speakers should serve you well.
