There are systems in this class that are sold without a DVD player and are designed to integrate with existing video setups where there is already one, such as a DVD recorder or a DVD/VCR combo unit. The speaker cabinets supplied with most systems in this class are generally fairly small compared to typical stereo speakers, and are meant for wall- or shelf-mounting in tight spaces. There are some systems in this class that are supplied with slim freestanding speakers that stand on the floor. This may be typical of higher-priced systems that are equipped with more powerful amplifiers or most of the "receiver-only" packages that do not come with a DVD player.
