Speakers - or loudspeakers - are the final link in your audio chain. By means of vibrating membranes, the electronic sound is converted into audible sound. Speakers should be of a very high quality since they have to perform a difficult task. Most loudspeakers contain multiple speakers to ensure that every frequency of the spectrum is perfectly audible. An amplifier is needed to deliver the right amount of power. Sometimes loudspeakers are equipped with built-in amplifiers to match exact specifications.
