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 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 ...
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.
The fundamental principle of bass management (also called LFE crossover) in surround sound replay systems is that bass content in the incoming signal, irrespective of channel, should be directed only to loudspeakers capable of reproducing it, whether the latter are the main system loudspeakers or one or more subwoofers.
Class XD (crossover displacement) is a proprietary and patented [1] amplifier technology developed in-house by Cambridge Audio.. First appearing in 2006 in the Azur 840A integrated amplifier, the Crossover Displacement design sought to combine the performance of a traditional Class A design with the efficiency of Class B but without the linearity and distortion limitations of Class AB.
In 1975 Ed Long [1] in cooperation with Ronald J. Wickersham invented the first technique to Time-Align a loudspeaker systems. In 1976 Long presented "A Time-Align Technique for Loudspeakers System Design" [2] at the 54th AES convention demonstrating the use of the Time-Align generator to design improved crossover networks for multi-way loudspeakers systems.
In 1986 Celestion introduced the System 6000, a double-dipole subwoofer system with active audio crossover to complement and enhance the SL series. In 1992 the Model 100, a final variation of the SL design, came to market. It featured a conventional, but highly refined MDF / wood veneer cabinet, dual inputs, updated mounted plates, improved ...
While this is the case, the subwoofer is not on a separate output as it is with 5.1 and higher audio. Instead, a low-pass filter (crossover) within the speaker system removes high and midrange frequencies from the sound card's output for the subwoofer. Games see a "4.1" speaker system as quadraphonic because DirectSound itself offers no ...
