2. Bi-wiring - Wikipedia

   en.wikipedia.org/wiki/Bi-wiring

   Amplifier and loudspeaker with two elements and crossover networks. Top: normal connection. Bottom: bi-wiring. Loudspeaker bi-wired using banana plugs. Bi-wiring is a means of connecting a loudspeaker to an audio amplifier, primarily used in hi-fi systems. Normally, there is one pair of connectors on a loudspeaker and a single cable (two ...

3. Bi-amping and tri-amping - Wikipedia

   en.wikipedia.org/wiki/Bi-amping_and_tri-amping

   A single amplifier can usually power a woofer and a tweeter only through a post-amplifier crossover filter, which protects each driver from signals outside its frequency range. Bi-amping of speakers requires double the channels of amplification and can be accomplished using two ordinary amplifiers in either a vertical or horizontal arrangement.

4. Vehicle audio - Wikipedia

   en.wikipedia.org/wiki/Vehicle_audio

   Some head units have built-in stereo amplifiers. Other car audio systems use a separate stand-alone amplifier. Every amplifier has a rated power level sometimes noted on the head unit with the built-in amplifier, or on the label of a stand-alone unit. Coaxial speakers: These are the most common type of car speakers and are often factory-installed.

5. Audio crossover - Wikipedia

   en.wikipedia.org/wiki/Audio_crossover

   A passive crossover splits up an audio signal after it is amplified by a single power amplifier, so that the amplified signal can be sent to two or more driver types, each of which cover different frequency ranges. These crossover are made entirely of passive components and circuitry; the term "passive" means that no additional power source is ...

6. Class-XD Amplifier - Wikipedia

   en.wikipedia.org/wiki/Class-XD_Amplifier

   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.

7. Loudspeaker time alignment - Wikipedia

   en.wikipedia.org/wiki/Loudspeaker_time_alignment

   However, there is a type of crossover called the LR4 or LR2 crossover, which has certain unique features that make time-alignment worthwhile for speakers that use it. This particular crossover has the property that at the crossover frequency the electrical summing is flat (i.e., there is no peak or dip) and the signals being sent to the woofer ...

8. Crossover distortion - Wikipedia

   en.wikipedia.org/wiki/Crossover_distortion

   The term crossover signifies the "crossing over" of the signal between devices, in this case, from the upper transistor to the lower and vice versa. The term is not related to the audio loudspeaker crossover filter—a filtering circuit which divides an audio signal into frequency bands to drive separate drivers in multiway speakers.

9. Bridged and paralleled amplifiers - Wikipedia

   en.wikipedia.org/wiki/Bridged_and_paralleled...

   Any conventional stereo amplifier can be operated in bridge or parallel mode provided that the common loudspeaker terminals (normally black) are connected and common to the ground rail within the amplifier. This would turn the stereo amplifier into a mono amplifier. Some two channel amplifiers, or stereo amplifiers, have the built in facility ...
