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.

Listening tests were performed to evaluate the improvement in the off-axis frequency response obtained by using very high slope filters. In the case of FIR filters, a very compact form of coding has been developed which requires only one convolution to give both the high- and low-pass filter outputs. The filters have been tested on the TM32020 digital signal processor. The subject of finite-duration impulse response (FIR) and infinite-duration impulse response (IIR) filters used to implement loudspeaker crossover filters is addressed.
