Clean crisp smooth sound without distortionthat is what you get with an AudioControl electronic crossover. Keep in mind that the most common recommendation for crossover frequency is 80 Hz.

Provides the best technical accuracy with the least complications and harmonic distortion.
Car audio crossover frequency. It is designed to take one signal and create specific output alerts. Most car audio systems use a 12 dB or 24 dB slope. And as I mentioned earlier -12dB per octave -12dBoctave is very common for both car and home audio systems.
Car Audio Crossovers. The modules which control the crossover the subwoofer and the Programmable Frequency Match circuit are underneath the top cover of the unit. The result is mostly high fidelity sound and enhanced sound quality.
A 12 dB slope is most suitable for sedans and coupes that have subwoofers installed in their trunk. Lets look at the sub say you have it crossed at 70Hz LP then 1 octave is 70 to 702140 Hz. Wherever the crossover controls are try setting the lowpass crossover for the subwoofer and the highpass crossover for the midtweeter amp somewhere between 70 and 90Hz.
The trace in yellow is a low-pass filter and the trace in green is a high-pass filter. Crossovers are often described as two-way or three-way which indicate respectively that the crossover splits a given signal into two frequency ranges or three frequency ranges. R L - is the impedance of the load speaker you will be using.
How to set crossover frequency for car audio system. To determine the crossover frequency a certain amount of capacitance will give you use the formula. Low Pass High Pass Band Pass for 4 Ohm Load.
R L 6283 x L F. Here are two crossovers both of which are set to 300 Hz. More about this later.
Listen to it play for a bit and determine in what range currently sounds the best. C - is the capacitance value in Farads - to convert to Farads divide the value shown on the side of the cap in uF by one million. That means that your sub will be playing at -24dB at 140 Hz.
If the crossover slopes can be adjusted set both the low- and high-pass slopes to the same setting probably 12 or 24dB per octave. An audio crossover is a handy electronic tool. Slope or Q-Factor determines the rate at which the audio systems volume will diminish as the frequency extends past the crossover point.
Set the front channel or front and rear if using both crossover switches to HP or however theyre labeled for the high pass function. The subwoofer does not have a supplied passive crossover use a Low-Pass Filter to block the high frequencies from being sent to the subwoofer. Set the crossover point around 10 Hz below the lowest frequency your speakers can produce without issue.
If adjustable try switching the slope and listen for any improvements in sound quality. Divide and conquer is the key to efficient use of amplifier power and effective use of each and every speaker. These indicators are composed of high- mid- and low-range frequencies.
Using a small screwdriver turn it. A slope of 12 dB per octave is a more gradual cut off. Low-pass and high-pass filters are denoted in hertz Hz whereas slope is denoted in decibels dB.
The most commonly used slope options found in car audio are 12 dB per octave or 24 dB per octave. It is measured in decibels dB per octave and the most common slope options used range between 12 dB per octave and 24 dB per octave. To determine the crossover frequency a certain amount of inductance will give you use the formula.
Low-pass filters do the opposite they pass audio information below the crossover frequency. The signals are then transmitted to the sound system of your rig. It is not a brick-wall style filter.
0159 C x Rh F. Now a crossover in simple terms is a setting that. Rh - is the impedance of the load speaker you will be using.
They split up an audio signal into two or more frequency ranges so that the signals can be sent to loudspeaker drivers that are designed to operate within different frequency ranges. To help you understand the incredible flexibility and control of the 4XS please refer to these block diagrams for both 2 and 4 channel operation. The crossover you use say a 4th order LR will cause a 24 dboctave drop in response at the crossover point.
As I mentioned earlier the slope controls the steepness of a crossover filter or how strongly it reduces blocks sounds you dont want to reach your speakers. Unfortunately understanding how they work and accurately setting crossover frequency for various speakers can be confusing. High-pass crossovers allow information higher than the set frequency to go to the speaker.
Adjust the crossover frequency control to the lowest setting this is usually around 50Hz for most amps. Advanced programmable and steep slope filtering trim frequencies to minimize.
