A STEREO is an audio system that contains two or more speakers and a receiver to amplify sound from a variety of sources. HiFi is short for high fidelity, which is a term used to describe audio systems that reproduce sound accurately and with minimal distortion. CD racks are shelves designed to store CDs and other media. A CD tower is a tall, vertical storage unit designed to hold CDs and other media.
