There are many different types of speakers available that can deliver excellent sound. Most models come as 2 speakers for stereo reproduction. There are some kits that include 3 speakers, the 2 speakers for left and right channels, plus a subwoofer that reaches super low frequencies. You ll find that some of these kits can compete with the performance of your home stereo system. For the most part, though, it isn t necessary.
Most computers can deliver very good stereo sound.
They use 2 speakers and an enhancement circuit to deliver a wider audio spectrum that feels like surround. Some higher priced models may even offer Dolby Digital Surround, which distributes sound into 5 distinct channels for home-theater applicability. These would require 5 or 6 speakers and offer a great experience when viewing DVD software on your computer system. Theoretically, the greater number of watts is believed to improve clarity of sound. With speakers this compact, wattage is only a small factor.
