☑ Tweeter Capacitor Impedance

A crossover network can be used in a limitless number of ways to help tailor frequency response. It seems putting these two speakers in series will be better as it will give a net impedance of 12 ohms.

Myths Facts About Loudspeaker Crossovers Identifying

Even though the crossover network stayed the same the impedance variation of the standard tweeter was causing problems in the frequency response.

Tweeter capacitor impedance. The woofer impedance is low 4 ohms at low frequencies but swoops upwards as the inductor has more and more of an effect. Assume 8ohm impendance is used and the cut off freq is 900hz so you need to use around 22uf capacitor. The tweeter impedance is low at high frequencies 4 ohms swooping upward at low frequencies.

For this tweeter with a nominal impedance of 4 ohms ive chosen a 68 uf cap. Lets create a mental picture of the two filter halves wired in parallel to the same source. Finally there are lots of different kinds of caps.

Then enter the impedance of the speaker you will be using with this filter in the box below that. The dc28 a regular soft dome tweeter had a varying impedance but the pt2b tweeters impedance was nearly constant over all frequencies like a resistor. Finally click the calculate it button to see the frequency this filter will be 3 db.

A balanced dome driver is a semi dome with equal reproduction area given the cone and dome portions of the driver. To use this calculator enter the amount of capacitance you have available in the first box. Capacitor uf rh ohms.

For magnetic tweeter the nominal impendance is around 4ohm to 8 ohm. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer. Connecting my 4ohm speaker and 8ohm tweeter tweeter in series with a capacitor in parallel results in a net resistance of 267 ohms and will cause a problem for my amplifier.

Semi dome design is one with a dome placed inside a cone. There are notch filters which can remove peaks in response shelving circuits that can attenuate above or below a given frequency conjugate networks to flatten impedance curves and a myriad of other possible filters. For piezo tweeter theoritically no cap is needed as piezo itself is capacitance in natural.

Dome tweeters are used in most home speakers and provide a smoother and more accurate sound.
