☑ What Capacitor Do I Need For A Tweeter

Even in hi fi use the minimum slope required for even moderate protection of a tweeter is 12db 2nd order while for professional use 18db 3rd order and 24db 4th order slopes are preferred. This will tame the tweeter down.

Tweeter 6 Ohm With Crossover Capacitor

Use 10 ohms for the woofer impedance and 35 ohms for the tweeter.

What capacitor do i need for a tweeter. The larger the ohm number you use will result in less output from the tweeter. You may or may not like the results. For piezo tweeter theoritically no cap is needed as piezo itself is capacitance in natural.

With an impedance of 4 ohms and a crossover frequency of 500hz you need an 80uf capacitor. Maybe try a 2 ohm to start. Now click the capacitance button to see the resulting value.

To use this calculator enter the amount of capacitance in the first two boxes they can be different values this is how you obtain the odd values in the charts above. Heres a chart for the 1st 2nd and 3rd order component values for crossover frequencies from 50hz to 10khz. Anyone know what size capacitorresistor do i should use for these horn tweeters.

If youre planning to build a passive crossover for these i suggest you use 3000 hz as the target assuming those spec. It takes the combination of a couple unique drivers and the willingness to accept some major compromises to do so. You can try adding a non inductive 1 4 ohm wire wound resistor in series between the plus wire and the tweeters input plus terminal.

Size of capacitor vs frequency it blocks. I designed a speaker earlier this year that uses a single cap and padding resistor on the tweeter with the woofer run wide open. Assume 8ohm impendance is used and the cut off freq is 900hz so you need to use around 22uf capacitor.

For best results you should use a non polarized or bi polar same thing capacitor rated at 100 volts or more. 375 square super horn tweeter frequency response. For magnetic tweeter the nominal impendance is around 4ohm to 8 ohm.

Then pick a series or a parallel connection. 1 it protects the tweeter from the application of too much power at low frequencies and 2 it helps us shape the response of the tweeter to match the response of the midrange. 4 20khz spl 94db at 1w1m low distortion light weight highly.

From what i have read it would seem i need to install some kind of series resistor to get the cleanest sound from these piezo horn tweeters. This does two things. You can see the green line is virtually unaffected there is virtually no decrease in the signal level above 2khz.

On the following graph the green line shows how the signal level drops off rolls off as the frequency decreases. In a simple passive crossover we use a capacitor to limit the amount of low frequencies that make it to the tweeter. Those are the impedances at 3 khz according to their plots.

Using only a capacitor is a recipe for a blown tweeter.
