The airmotiv 4 was designed for applications where accurate sound is required and space is at a premium. It's at home in a small studio (as a near-field monitor) or a home studio. Unlike most really small monitors, it delivers ample clean bass for close listening, or even for an entire room at moderate listening levels, without a sub-woofer.
Because of its small size and low cost, the airmotiv 4 also opens up all sorts of interesting possibilities. They make great computer speakers. You can connect a pair to a portable CD player or an iPod to make a fantastic mini-system for a small room or office, and they sound incredible when connected to a networked music client. You can connect a pair directly to a preamp or a DAC, or connect a set of five to a surround sound pre/processor, and they'll make a major improvement to the sound of your high-end TV.
