The Compaq Premier Sound PS110 Speakers are designed to exceed the customer's expectation of audio quality in small, compact, cost-effective loudspeakers using the following advanced technologies: wide frequency bandwidth down to 60 Hz allows for controlled, smooth, "high-fidelity sounding" bass, an amplifier capable of transmitting 18 W per channel so distortion is controlled at both typical as well as low frequencies levels that require more power.The transducer (speaker component) has excellent performance through its long voice coil, exceptionally large magnet structure and increased power handling capability. Bass reflex loudspeaker enclosures contain the transducers and amplifiers that are specifically designed to enhance the bass output in a small space. The 10 stages of fixed equalization "shape" and "push" the music back so that a listener sitting 2-3 feet away is not blasted by the music, but rather hears a natural sound reproduction.
