A good speaker stand is a vital part of any good home theater system or audio system. Not only will a good stand make the speakers look better, it also can dramatically improve their performance. A quality speaker stand is designed to perform two important tasks: elevate the speaker to the proper height, and remove excess energy from the speaker cabinet. 

Why is it necessary to elevate the speaker? Because high frequencies are directional, the high frequency driver, called a tweeter, should sit at a height equal to or just above the listener's ears. Proper tweeter elevation improves high frequency sound and adds an openness and ambience to the performance you can't get any other way.
