Horizontal-only playback rigs are the most commonly deployed and most extensively researched Ambisonic speaker systems, because they constitute an economic next step after conventional stereo. They can reproduce full-sphere content, but elevated sources will be projected onto the horizontal plane, and sources at zenith and nadir will be ...
Folded-horn bass guitar rigs have remained rare due to their size and weight. As well, since the 1990s, most clubs have PA systems with subwoofers that can handle the low range of the bass guitar. The more common use of tweeters in traditional bass guitar amplifiers in the 1990s helped bassists to use effects and perform more soloistic playing ...
As shown in the bass management block diagram, a 5.1-channel audio system consists of five discrete, full-range main channels (front left, center, front right, surround left, and surround right), plus a band-limited low-frequency effects (LFE) channel for added bass (this corresponds to the .1).
Using a crossover to separate the sound into low, middle and high frequencies can lead to a "cleaner", clearer sound (see bi-amplification) than routing all of the frequencies through a single full-range speaker system. Nevertheless, many small venues still use a single full-range speaker system, as it is easier to set up and less expensive.
Tri-amping is the practice of connecting three channels of amplification to a loudspeaker unit: one to power the bass driver , one to power the mid-range and the third to power the treble driver . The terms derive from the prefix bi- meaning 'two', tri- meaning 'three', and amp the abbreviation for amplifier .
Another way to get an extended range is to add strings. The most common type of bass guitar with more than four strings is the five-string bass. Five-string basses often have a low-B string, extending the instrument's lower range. Less commonly, five-string instruments add a high C-string, extending the higher range.

As well, a bass player with a four string electric bass can use an octave pedal to obtain low notes that would normally only be obtainable with a five-string bass with a low "B" string. A harmonizer is a type of sophisticated pitch shifter that combines the altered pitch with the original pitch to create a two note harmony based on the original ...
