Speakers

Speakers turn the data that represents audio into sound you can hear. Speakers come in all shapes and sizes, and PC speakers are available in 2.0 (two speakers), 2.1 (two speakers plus a subwoofer), 5.1 (five speakers plus a subwoofer) and 7.1 (seven speakers plus a subwoofer) for increasingly immersive sound. There has also been a recent trend in using battery-powered Bluetooth-connected speakers for a listen-anywhere sound.
