500 Hz to 2 kHz
The Bass Range Covering about 1.5 octaves, from 80 Hz to 250 Hz, this range of frequencies determines the fatness and fullness of the instrument's sound. Equalization is usually applied centered around two frequencies, 100 Hz and 200 Hz. For guitars and bass, the 100 Hz range tends to add body and fullness. A mid-range speaker is a loudspeaker driver that reproduces sound in the frequency range from approximately 300 to 5000 Hz. It is also known as a squawker. A mid-range driver is called upon to handle the most significant part of the audible sound spectrum, the region where the most fundamentals emitted by musical instruments and, most importantly, the human voice, lie. Best Answer: In a two-way system there is a woofer and tweeter that together produce the range of frequencies. In a three-way system a mid-range speaker produces a mid-range of frequencies. This places less burden on the woofer and tweeter, typically reducing distortion. However a carefully designed crossover network is normally required for good results.  The audio spectrum is the audible frequency range at which humans can hear. The range spans from 20 Hz to 20,000 Hz and can be effectively broken down into seven different frequency bands, with each having a different impact on the total sound. Midrange: 500 Hz to 2 kHz. The midrange determines how prominent an instrument is in the mix. Boosting around 1000 Hz can give instruments a horn like quality. Excess output at this range can sound tinny and may cause ear fatigue. The Mid Range The Mid Range band of frequencies covers two octaves from 500 Hz to 2 kHz. This range can give a horn-like quality to instruments (500 Hz to 1 kHz) and a tinny sound (1 kHz to 2 kHz) or a telephone-like quality (all of the range). Equalization usually centers around 800 Hz and 1,.5 kHz. Covering about 1.5 octaves, from 80 Hz to 250 Hz, this range of frequencies determines the fatness and fullness of the instrument's sound. Equalization is usually applied centered around two frequencies, 100 Hz and 200 Hz. For guitars and bass, the 100 Hz range tends to add body and fullness. The 60hz-90hz range is where we notice the greatest perceptible changes in bass response.. Try a test tone and see just how well you hear 20hz or even 32hz, compared with the same volume of 60hz or 90hz. Mid-Bass. (Approximately 140hz-400hz). Mid bass has lots of instruments included in its frequency range.  In statistics, the mid-range or mid-extreme of a set of statistical data values is the arithmetic mean of the maximum and minimum values in a data set, defined as: The mid-range is the midpoint of the range; as such, it is a measure of central tendency. Low Midrange: 250 to 500 Hz. The low midrange contains the low order harmonics of most instruments and is generally viewed as the bass presence range. Boosting a signal around 300 Hz adds clarity to the bass and lower-stringed instruments. Too much boost around 500 Hz can make higher-frequency instruments sound muffled. Midrange: 500 Hz to 2 kHz. The midrange determines how prominent an instrument is in the mix. Boosting around 1000 Hz can give instruments a horn like quality. Excess output at this range can sound tinny and may cause ear fatigue. The woofer driver is responsible for low, bass frequencies. Deep, pulsating notes come from the woofer. In technical terms, the range of a woofer is between 20 Hz, the lowest range of human hearing, and 1,000 Hz. However, some woofers that have to cover part of the mid-range can operate as high as 5,000 Hz. Subwoofers are a type of woofer that plays the very lowest frequencies. They operate from 20 Hz up to 120 Hz Midrange frequencies would be 500Hz to 5,000Hz, and high frequencies would be 5,000Hz-20kHz. However, the range is often further divided into sub categories such as midbass and upper midrange. Familiarity with these ranges enables us to determine how a speaker should sound based on the Frequency Response Graph.
