In this video I have explained about Passive Crossover. How to make passive crossover yourself for 2 way or 3 way speakers. I have also explained about the different orders of crossover. By using these methods you can easily make a good and low cost crossover for your speakers.

Audio crossovers are a type of electronic filter circuitry used in a range of audio applications.[1] 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. 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. Crossovers are used in loudspeaker cabinets, power amplifiers in consumer electronics (hi-fi, home cinema sound and car audio) and pro audio and musical instrument amplifier products. For the latter two markets, crossovers are used in bass amplifiers, keyboard amplifiers, bass and keyboard speaker enclosures and sound reinforcement system equipment (PA speakers, monitor speakers, subwoofer systems, etc.).
Crossovers are used because most individual loudspeaker drivers are incapable of covering the entire audio spectrum from low frequencies to high frequencies with acceptable relative volume and absence of distortion. Most hi-fi speaker systems and sound reinforcement system speaker cabinets use a combination of multiple loudspeaker drivers, each catering to a different frequency band. A standard simple example is in hi-fi and PA system cabinets that contain a woofer for low and mid frequencies and a tweeter for high frequencies. Since a sound signal source, be it recorded music from a CD player or a live band's mix from an audio console, has all of the low, mid and high frequencies combined, a crossover circuit is used to split the audio signal into separate frequency bands that can be separately routed to loudspeakers, tweeters or horns optimized for those frequency bands.
Passive crossovers are probably the most common type of audio crossover. They use a network of passive electrical components (e.g., capacitors, inductors and resistors) to split up an amplified signal coming from one power amplifier so that it can be sent to two or more loudspeaker drivers (e.g., a woofer and a very low frequency subwoofer, or a woofer and a tweeter, or a woofer-midrange-tweeter combination).
A passive crossover splits up an audio signal after it is amplified by a single power amplifier, so that the amplified signal can be sent to two or more driver types, each of which cover different frequency ranges. These crossover are made entirely of passive components and circuitry; the term "passive" means that no additional power source is needed for the circuitry. A passive crossover just needs to be connected by wiring to the power amplifier signal. Passive crossovers are usually arranged in a Cauer topology to achieve a Butterworth filter effect. Passive filters use resistors combined with reactive components such as capacitors and inductors. Very high performance passive crossovers are likely to be more expensive than active crossovers, since individual components capable of good performance at the high currents and voltages at which speaker systems are driven are hard to make.
First order
First-order filters have a 20 dB/decade (or 6 dB/octave) slope. . First-order filters are considered by many audiophiles to be ideal for crossovers. It also uses the fewest parts and has the lowest insertion loss (if passive). A first-order crossover allows more signal content consisting of unwanted frequencies to get through in the LPF and HPF sections than do higher-order configurations.
Second order
Second-order filters have a 40 dB/decade (or 12 dB/octave) slope. This order is commonly used in passive crossovers as it offers a reasonable balance between complexity, response, and higher-frequency driver protection.
Third order
Third-order filters have a 60 dB/decade (or 18 dB/octave) slope. Third-order acoustic crossovers are often built from first- or second-order filter circuits.

Hi! Can you give information how to select impedance of speaker/ woofer/ tweeter and size. Ex 8 in, 10 in etc.

[@ig_ignite150]

That depends on ur amplifier's output. Whatever amplifier u are buying, firstly check his datasheet and see on which impedance he is performing best. Then chose ur respected speaker of desired impedance.

[@celebrationsllc]

@@LofiPlay9998 thanks bro but active crossover is always not possible due to seperate wiring and infra cost.

Passive crossover will always result in some audio power loss at those components. So either use more powerful amplifier, or use active crossover
