A crossover is a device that separates audio signals into different bands. The bands can either be, low, mid or high depending on the speaker set up. The bands are set to specific output divisions to highlight the tones to the best. The low tones are taken and directed to the sub, whereas the mid and the high are guided to the woofers and tweeters. If these different bands are not separated, they can cause muddling of sound or lag depending on the setup. Passive crossovers are very important and therefore should be put next to every speaker. Most home speakers have a two-way crossover which blocks the high tones from the woofer and the low tones from the tweeter in order sounds of high quality.
The following are the ways how you can determine the frequency of your home systems:
Checking the speaker frequency range
You can determine the crossover range by its slope and measure it in octave/dB. A steep slope results in a narrow range. For example, if you have a crossover of about 6 octaves and the crossover frequency is at 100Hz, and you want to raise the crossover to a magical rate, you should perfectly flat the DC to the light bandwidth speaker and play a tone of 100Hz through the speaker at a given level. Tune the pitch down to a sound of about 50Hz and the tone will be about 6dB quieter. A crossover regulates the range of frequencies that is shared by one or more speakers. Generally, a crossover makes a tone to get quieter when the pitch goes down.
Consider using the standard
80Hz is the default frequency of most systems. It is a frequency that is high enough to produce a bass requirement from a midbass speaker. It results from the design of bookshelf sized speakers that are of the better match for the commonly raised in trenched opinions about sizes of speakers that are aesthetically acceptable. Furthermore, an 80Hz frequency is not so high, and therefore the bass drivers have an easy time in giving responses to problems that occur due to inductance. The frequency is low enough and therefore it is hard for the sub to localize. If you have a system with an adjustable crossover point, it is advisable to make a brilliant choice that best fit your mains and sub.
Trying out the usual’s
When setting up a system for the first time, it is good to set a range of frequencies to try out the system. With bass management functions, it is good to have some critical listening and experimentation of your system to achieve the best sound results. Where the frequency range is known, the crossover point can be set roughly to 10Hz above the lowest frequency that the speakers can reasonably handle. However, where the ideal frequency of the speaker is not well known, it is advisable to use the system matching tool which usually contains the perfect recommendation of the system and give the best frequency of the system.
