A collection of audiovisual equipment that emulates the movie theater experience in the home. Most home theaters consist of a TV or projection system combined with an amplifier, surround sound processor (Dolby Digital aka AC-3, DTS or Pro Logic), speakers--including a subwoofer--and a source (DVD, laserdisc, VHS). Definitely the cause of much financial difficulty, but for many people it's worth it to be able to blast your neighbors out when Mr Shadow shows up in The Fifth Element.
