A333U 2.1 multimedia speaker |
The 2.1 speaker, the 5.1 speaker and the 7.1 speaker are the most commonly used surround sound products. Factually speaking, these are codes that explain the configuration of each speaker system. Whilst the first numeral represents the quantity of full range speakers the multimedia system comprises, the second digit stands for the LFE (Low Frequency Effect) channel of the system. Hence, a 2.1 speaker system consists of two full range speakers as well as 1 LFE channel and a 5.1 speaker system includes five multimedia speakers and 1 LFE channel and so on and so forth. The LFE channels are employed to carry very low bass sound on their channel and are very useful when there is no subwoofer as they facilitate flow of low bass audio to the main speakers.
