Home theater systems are great for amplifying any type of sound. Thus, they are excellent choices for either listening to music or singing karaoke because both of these activities do require sound to be amplified. For singing karaoke, you’ll want the sound of your voice or whomever is singing to be amplified. Listening to music is all about the sound of your music, and a great home theater system will do an amazing job at amplifying the sound of your music to the room you’re in and, if it’s loud enough, even through your entire house!
