Product introduction:

finished welding power amplifier board, full-type wiring. Works directly with power, audio, and passive speakers. This product uses two TPA3116D2 digital amplifier chips as its core. One is channel power amplification, bridge drive subwoofer, small size, high efficiency, high power, etc. Materials used regardless of cost, the capacitance of WIMA, Siemens, and Nikon fever capacitors. High-quality Taiwan-made high-quality sealed potentiometer, original TPA3116 chip, dedicated bass audio chip. The board circuit is simple and reliable. Operating voltage single power supply 12V-24V. Left and right channel output 50W*2, the subwoofer output 100W,  efficiency can reach more than 90%. The small size of the board makes it very flexible and convenient to use and install. All components used for genuine device use can be long-term stable work.

Description:

It is recommended to use a 19V/4-6A power supply, then connect to the subwoofer, subwoofer 5-10 inch, impedance 2-4 ohm, speaker sensitivity about 90dB, and speaker power of 40W-200W. Left and right channels connected to a pair of satellites, speaker 4-6 inches, impedance 4-8 ohms, speaker sensitivity about 90dB, speaker power 30W-60W, can be a bookshelf box with two frequencies.

Power needs to be reached. Use a 24V/5-10A power supply, then you can use subwoofer 1, subwoofer 6-12 inches, impedance 2-4 ohms, speaker sensitivity about 90dB, speaker power 60W-200W. A pair of speakers with left and right channel satellite box 4-6 inches, impedance 4-8 ohms, speaker sensitivity of about 90dB, and speaker power of 40W-80W, can be two frequency bookshelf boxes.

Don’t need much output power, you can use power more than 12V-15V/3A-5A, then subwoofer 1, subwoofer 4-6 inches, impedance 2-4 ohm, speaker about 90dB Sensitivity, speaker power 30W-100W; left and right channels connected to you a pair of satellites, speaker 2.5-5 inches, impedance 4 ohms, speaker sensitivity about 90dB, speaker power 10W-50W, can be a two-frequency bookshelf box can.

Note:

the amplifier is connected to the speakers, not the speakers! The speaker is an accessory speaker, not the same as the speaker, the effect is different. If the loudspeaker is not set up as a loudspeaker, it sounds the same, but because the front and back cones of sound phase oscillation are opposite, the sounds are offset from each other (commonly known as an acoustic short circuit) and sound fainter. increase! And the speaker has no box, no resonant cavity, and can’t produce bass!

If building your own speaker, work through general speaker manufacturing tutorials, scientific calculations for proper box volume, guide tube size, frequency points for dividers, subwoofers with no frequencies, thick wood, and sound absorbing cotton. Please paste and take appropriate action. No work is left out.
