A Speaker is an electromechanical transducer that converts an electrical signal into sound. A complete speaker system consists of an enclosure that incorporates one or more drivers and additional electronics. A speaker is one of the most variable elements in any audio system, and is responsible for marked audible differences between otherwise identical sound systems.

A speakers performance or accuracy in reproducing a signal without adding distortion is significantly poorer than that of other audio equipment. Most speaker systems require more than one driver, particularly for high sound pressure levels or high fidelity applications.

However, the speakers have a wide range of application, and their popularity has defined the increasing demand for expert evaluation. On the basis of the popular reviews, here is a brief guideline on the top three best speakers of 2007 -
