L1-C1 and L2-C2 (see the last circuit wiring schematic in the figure). For the mid-range, there a two pairs of caps-inductor, i.e. For the tweeter, capacitor-inductor pair should be selected based on f2 (10 kHz). For the tweeter, you have to choose the capacitor value for f2 (10 kHz) at 8 ohm, a 1.4 uF capacitor will be needed.įor the second order filter (12dB/octave roll-off), f1 (200 Hz) should be used for selecting the capacitor-inductor pair for the woover.

You’ll need a 70uF capacitor and a 0.18mH inductor to be wired in series with the mid-range speaker. Look the value of capacitor using the f1 (200Hz), and look the value for the inductor using f2 (10 kHz). For the mid-range speaker, you need a capacitor and an inductor to be wired in series. Connect this inductor to your woover in series. You’ll find a 9mH value for the inductor. If you want a first order filter (6dB/octave roll-off), look at the table for 200Hz, 8 ohm. Let’s define the crossover frequency f1=500Hz and f2=10KHz. Let say you have an 8 ohm woover, 8 ohm mid-range speaker, and an 8 ohm tweeter. For the tweeter, you need to wire the inductor in parallel with the tweeter, then connect the capacitor in series.ĭesigning A Crossover Network for Three-Way Speakers Systemįor three-way speaker system, you need to define the first crossover point f1 for transition between low frequency and mid frequency, and the second crossover point f2 for the transition between mid frequency and the high frequency. One capacitor should be wired in parallel with the woover, and then connected in series with the inductor. Provide two 13uF caps and two 1.8mH inductors. Look at the second table (12dB/octave) 1 kHz, 8 ohm, and you’ll find 1.8 mH and 13uF value for the inductor and capacitor. If you need a second-order filter for your crossover network, then you need to provide two caps and two inductors. For this case you’ll get 1.2mH for the inductor and 20uF for the capacitor. Then you look-up the table to find the value for the inductor to be installed in series with the woover, and the capacitor to be installed in series with the tweeter. First you have to select the crossover frequency, say 1 kHz. Let’s say you have a 8 ohm woover and a 8 ohm tweeter. The first order crossover network is the simplest, need only a capacitor for the high pass and and an inductor for the low pass.ĭesigning A Crossover Network for Two-Way Speakers Systemįor 2-way speaker system, in case of the first order filter, you just need a capacitor and inductor. The circuit configuration of the circuit is simple, as shown in the figure below. This point is called crossover frequency point. To give a flat response, you need to set the corner frequency of each filter at the same point, so the response of will cross-over (overlapped) in the transition area of each filter band). Sometimes when you have only two speakers in a set with a woover and a tweeter, then you need only a low-pass and high pass filters. You need a low-pass filter crossover network for woover or sub-woover, a band-pass filter for mid-range speaker, and a high-pass filter for tweeter. First order crossover network will give 6dB roll off curve for the frequency response, and the second order one will give 12dB/octave roll-off. Both first order and second order passive filter will be explained in this article. This articles describes how you can design your own crossover networks for your Hi-Fi speaker set. Crossover network for speaker can improve the quality of the sound, reducing the distortion level caused by excessive signal beyond the speaker’s frequency response.
