Passive speakers need to be driven by a power amplifier. In this category of our shop you will find powerful amplifiers for every application. Besides the traditional Class AB amplifiers, digital Class D amplifiers dominate the market today. The advantage lies in their high efficiency. Comparatively little power is lost as heat, which also dramatically reduces the size and weight of the heat sinks. Modern switching power supplies are also very efficient and light. Together, this allows for extremely high power in a handy format. Subwoofer power amplifiers in particular often require high power. In the range of several thousand watts, Class H power amplifiers become necessary. Of course, you will find all of this here - and from top-class manufacturers such as: Crown, DBX, QSC, Dynacord, Yamaha, Bose, Lab.Gruppen and others.
