Full-range speaker

Broadband speakers are speakers that cover the entire audible frequency range.

In contrast to multi-path systems, they do not need a crossover, but some are equalizing circuits such as series resonant circuits for frequency linearization necessary. In contrast to systems with multiple radiate sound from only one speaker, thereby resulting from different spatial arrangement of the individual components in multiway systems distortion, which manifests itself in better speech intelligibility omitted. In addition, full-range speakers are characterized by a significantly increased compared with conventional speaker systems spatiality, voice separation and image sharpness. Commercially they are therefore often used in theaters as additional rear speakers as nearfield monitors in studio or in radio and TV sets.

The conflict in the development and deployment of broadband loudspeaker chassis is that sufficient air volume must be displaced to low frequencies, for the reproduction of high frequencies but small chassis sizes due to lower moving masses and less strong sound focusing advantage. Thus, while in the professional sound great range chassis predominate ( classic example: theater speakers ), come in the field of Hi- Fi applications rather small to medium range chassis for use. To ensure a bass that is not too quiet compared to the often high-efficiency high - and mid-range of small full range, often one uses horn enclosures that allow a higher gain of the bass range as a bass reflex or transmission line cabinet.
