When choosing an audio system for your home, first ask yourself what you are going to be listening to. Are you looking for an audio system to connect with your iPod® or digital music library? Is it for multi-channel movies or just improving how your TV sounds? If you want to watch movies, TV or play games in surround sound, then you should consider a 5.1 or 7.1 surround sound system. If you are looking to improve how your iPod sounds in your bedroom or desktop, consider a 2.1 or 5.1 multimedia system.
