merci pour la video :) une petite question sur les watts que j'ai du mal comprendre. lorsque qu" un fabriquant d'enceinte autonome annonce une puissance de 300 wats es ce vraiment 300wats ???car ici je vois 45wats qui me semble tres !!! cela est il dur de fabriquer un ampli maison de 300wats?
thanks for your attention. In this amplifier, an IC is used, which is designed for 4 outputs with a power of 45 watts and an impedance of 4 ohms. It requires 12 to 24 volts of electricity. Of course, the higher the voltage, the stronger the output power. Regarding the 300W amplifier, I can say that it is not difficult, but the type of amplifier and its voltage are important. I will try to make a video about a suitable circuit with this power in the future. 👍
Of course, to have a good sound from the speakers, be sure to put them in a suitable box. This video is just a tutorial on how to make a 3way crossover and at the end we will take a simple test of its output. Of course, I made another video where I installed the same crossover in a speaker and I recommend that you watch that video as well. I put the link here for you. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VUqTXF9uPqQ.html
Excellent tutorial, one question: Can this circuit be used for a 12" speaker, a 4" speaker and a 2" tweeter? The question is the values of the coils and their impedance. greetings.
Thank you for your support. You saw in the video that I tried on woofer 12", midrange 6.5"and tweeter 3"and a total power of 200 watts. Of course, I had these speakers at the moment. But this circuit is set to 4 ohms impedance and it will definitely have a good performance in your desired system.
Hi dear friend. You asked about the 150 watt circuit and I gave the wrong answer. I apologize for this. I made a video about the 300 watt crossover circuit. I recommend that you watch the video that is better for the speakers you want.
Calculate the output of your home speaker in terms of RMS. The same crossover can be used in most of them. For example, 1000 watts is approximately 250 RMS.
I also recorded the video with a mobile phone and unfortunately, the bass sound in the microphone of mobile phones is a little bad. Thankful. Your opinion is valuable for us
It can support up to 150 watts. If the tweeter sound frequency is too high, you can replace the capacitor 2.2uf instead of 0.47uf. You can also add 4 meters of wire with the same diameter for the woofer coil to make it bass sound better.
