- 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.
Mai to crossover ghar or kese banaye dekhne aaya thaa pr aapne to physics padha di🙃
Very interesting and useful video. Thank you very much for your initiative.
You are a very sincere person who shares his knowledge for the benefit of all. People like you are hard to find. Best of luck!
Sir such a complicated subject but you explained it in very easy way... Great Sir...
Thanks and welcome
@@WhatIThink sir TA8225h ic ke bare me bataye
Awesome Explanation Sir.. Please upload more videos on audio amplifier related topics...
This video is very much helpful for me. Because coil building is a very difficult job... and you explained it nicely in this video. Thank you so much sir. I bulit amplifiers from my childhood... it is my hobby. Please make videos on MOSFET and VALVE amplifier boards , how they work.
Sure I will
Sir maine aapse ye question Crossover Live question answer main pucha tha but passive mention nahi kia tha. Bahut bahut dhanyawaad aapke video ke lie.
Hi!
Can you give information how to select impedance of speaker/ woofer/ tweeter and size. Ex 8 in, 10 in etc.
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.
वाह सुधीर जी
आपने बहुत मेहनत की है इस क्रॉसओवर को बनाने में।
बहुत बहुत धन्यवाद
Best sir🙏🙏🙏🙏🙏♥️♥️♥️
Excellent Sir....want crossover for center speaker. 2 mid-range - 8 ohms drivers and 1 tweeter - 12 ohms. Can you share how to calculate? 12 db
Mid-Woofer driver is Fountek FW100B
Tweeter - 12 ohms from my old sony center speaker
Thank you Sir. Very very informative for audio hobbyist .
👌👌👌
Nice video that s informative
Now we want a modern time crossover
Like active crossover
Using simple op amp and single ic 2.1channel amp using tda 7377 low power and tda 7388 high power that is very simple operation no extra components requires and cheap in price
Thanks 🙏🏻
Thank you for the information. U r simply superb. If college professors explain like this there will be no knowledge less engineers in India. Keep up the good work.

Sir, passive crossover mein lagne waale resistor ki watts kaise nikale? Koi simple explanation de dijiye example calculation ke saath.
सर, आपने बहुत अच्छा तरीका समझाया है🙏
परन्तु एक #प्रश्न- बुफ़र 60W का है तो ट्विटर 25W का लेना है🤔 अगर स्पीकर भी जोड़ा गया है तो 100W के एम्पलीफायर के साथ तीनों को क्रमशः कितने W का लेना चाहिए ताकि 100W एम्पलीफायर पर अच्छा रहेगा।
100 watt amp ke saath 50 watt woofer 25 watt speaker aur 10 watt tweeter.
sir ek que hain coil se related agar hamme speaker ka coil banana ho to ky formula use krna hain speaker coil to bnalete hain but dusra copy krke but agar khudh apne calulations acording double magnet ya single magnet m coil design krna ho to kaise kr ..................sir plz reply dejiyega

I have tried 3 different cross over but there is significant drop in sound. Pls let me know in case any crossover available without impacting the loudness of sound.
Use active
@@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
Sir......calculator me impedance jo hain..... O wala full speaker box ka impedance hain? Yea fir sari speaker ka jo ohm hain o hoga....
Jesa mere box main mid tweeter woofer sare cis 8 ohm ka hain..... 2 woofer 1 mid 1 tweeter
Mera box ka total dc impedance hain 4 ohm..... To ab me calculat kis ohm ko pakar ke karu? Batayiye plz
From Bangladesh love you sir
Sir please tell can we use passive crossover with whuzi audio mt21 amp or we have to use a better amplifier? And how to calculate overall resistance and rms of speakers with crossover?
lovely
The most awaited and informative video. Thank you sir for the way you explained. Cleared all my doubts.
Very important video with very great youtubeer
mast video
Please correct me if I am wrong. I think all speakers have a upper cut off and lower cut off frequency..here you are doing with just one cut off frequency .Please clarify .
In 2 way crossover cutoff frequency will be same for both but one will be high pass and other will be low pass.
@@WhatIThink .I am talking about the speaker itself..I think ,any given speaker will have two cut off frequencies..high and low .
Bahut hi badiya
