The connection circuit diagram of speaker and high bass frequency divider

Published:2011/4/14 2:19:00 Author:Ecco | Keyword: speaker , high bass frequency divider

The connectionmethod of speaker and high bass frequency divider is shown as the chart 212: The inductors and the bass speakers connect in series, capacitors and the tweeter connect in series. The capacitor is used as AC capacitor that made by two small-capacity capacitors, inductance coil can be self-made. If it's a 10-inch box speaker, and the power is between 5 ~ 10W, the inductance coi could choose the size of 0.85mH. If chosen an empty skeleton with the core diameter in 3cm, it can be made by the line with the diameter in 0.8 to 1.0 mm and rolled with 300 laps.   (View)
