Most, if not all minisystems, come with at least one set of speakers. If you ve already invested in speakers and still wish to purchase a minisystem, you ll want to make sure that they ll be compatible with the system before making the purchase. Average human hearing spans a range of 20 to 20,000 Hz. A subwoofer emphasizes those frequencies on the low end of our hearing spectrum. Adding a subwoofer adds a certain bigness or dimensional depth to the overall sound.
Some systems have an integrated subwoofer or an output for an optional subwoofer.
Usually, external subwoofers come with an integrated amplifier while integrated units have a separate amp channel. The place for subwoofers is usually on the floor in a home audio system. Most systems have an output port for an additional subwoofer. How high or low a system is priced reflects the quality of the components and overall accuracy and clarity of the sound. Because of the mere nature of minisystems and the way they are built, when you buy any minisystem, you get a lot for your money.
