Satisfactory output of the complete system comprising the audio crossover and the loudspeaker drivers in their enclosure(s) is the design goal. Such a goal is often achieved using non-ideal, asymmetric crossover filter characteristics. [5] Many different crossover types are used in audio, but they generally belong to one of the following classes.
From about 1900 to the 1950s, the "lowest frequency in practical use" in recordings, broadcasting and music playback was 100 Hz. [9] When sound was developed for motion pictures, the basic RCA sound system was a single 8-inch (20 cm) speaker mounted in straight horn, an approach which was deemed unsatisfactory by Hollywood decisionmakers, who hired Western Electric engineers to develop a ...
"DMS" is the contraction for "domestic monitor system", and is designed to be driven passively in the home setting – it incorporated a crossover within the loudspeaker cabinet. The Isobarik PMS ("professional monitor system") loudspeaker launched in 1977, destined for the professional market is without the internal crossover.
It is designed to be amplified by 10 dB on playback and summed into the signal going to the subwoofer. The LFE channel for movies has a frequency range extending to 120 Hz, and some AV receivers apply a 120-Hz low-pass filter during playback, and this frequency is independent of the settings of the low-pass and high-pass filters that are ...
Bi-amping - An active crossover with two amplifiers.. Bi-amping and tri-amping is the practice of using two or three audio amplifiers respectively to amplify different audio frequency ranges, with the amplified signals being routed to different speaker drivers, such as woofers, subwoofers and tweeters.
From this point, connections are made to the loudspeaker drivers – usually through audio crossover networks. In bi-wiring, each loudspeaker has two pairs of connectors and two cables are run from the same amplifier output to the speaker cabinet: one for the high frequency or tweeter driver and one for the low-frequency driver (through two ...

A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]
