In the diagram, a 60 Hz crossover frequency has been illustrated, but this can typically vary between 40 and 80 Hz. The LFE channel is a separate channel that contains low frequencies only, and it was originally added to magnetic 70mm-movie soundtracks in the 1970s, to be reproduced through subwoofers. [ 5 ]
An N-way loudspeaker usually has an N-way crossover to divide the signal among the drivers. A 2-way crossover consists of a low-pass and a high-pass filter. A 3-way crossover is constructed as a combination of low-pass, band-pass and high-pass filters (LPF, BPF and HPF respectively). The BPF section is in turn a combination of HPF and LPF ...
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]

The Perry Preschool Project was a study on the impact of pre-kindergarten programs on outcomes for disadvantaged youth. The availability of high-quality pre-kindergarten education was found to have a statistically significant association with higher high school graduation rates, lower crime rates, lower teen pregnancy rates, and better economic ...
This frequency is known as the free-space resonance of the loudspeaker and is designated by F s. At this frequency, the voice coil is vibrating in the speaker's magnetic field with maximum peak-to-peak amplitude and velocity. The back EMF generated by this movement is also at its maximum. The electrical impedance of the speaker varies with the ...
Three dogs attacked their owner at a San Diego park Friday, killing the man and injuring another person, according to authorities and the Humane Society.
It was the first product released in the JumpStart series and, as its name suggests, it is intended to teach kindergarten students. According to the Knowledge Adventure founder Bill Gross, it is the first educational software program that covers the entire kindergarten curriculum. [1] It was ported to the Windows and Macintosh systems in 1995 ...
