Speaker Impedance Calculator Online
The following application will calculate the load of a given set of speakers wired in some combination of series parallel or both series and parallel. The calculator can be used for 2 3 or 4 speakers wired in parallel.

Simply type the impedance of each speaker into the white boxes or use the drop down values.
Speaker impedance calculator online. If a speaker impedance rating is 4 ohms that speaker is typically a high end audiophile speaker that needs an amplifier that has the ability to provide more power. This means that given the same output voltage the current demand on the amplifier will be increased. Get help for the speaker box designer determine the dimensions of your speaker box based on the calculated volume determine if your driver works best in a sealed or ported enclosure calculate the displacement volume for your driver read the speaker box design tutorial close.
A loudspeaker producer will likely build a 4 ohm speaker be he knows what type of amplifier would be needed for it to get the appropriate sound. Any values left blank will be ignored by the program. Comment request god knows how all those formulas work but i had to find the impedance of a circuit with 18 ohms resistance 100mh of inductance and a 50hz supply.
Welcome to speaker impedance. This is just a simple fact. In reality the impedance will vary with frequency and more factors such as coil temperature come into play.
The speaker ohm rating is an indication of the speaker s ac impedance which varies with the frequency of the input signal. Remember calculations are only to be used as a guide. A schematic of a impedance.
In this case 16 ohms. When speakers are connected in parallel the impedance is reduced. Use n a for unused speakers in this calculator.
An impedance equalization circuit also know as a zobel circuit can be used to counteract the rising impedance of a voice coil caused by inductive reactance. This website calculates the nominal impedance created with different combinations of wiring speakers together. The cause of this impedance rise is due to the speaker s voice coil inductance l e.
Speaker zobel impedance equalization network circuit calculator. This is why the spec sheet indicates this speaker to have an 8 ohm nominal impedance. This variation of the speaker s impedance can be seen on the speaker s spec sheet impedance curve.
Purpose of use homework. Please enter the impedance not the dc resistance for how you plan to configure them. The total impedance will be calculated for the entered speakers.
If your amplifier will drive a 4 ohm load the best pick is the one that generates a 4 ohm load. If your amplifier will drive an 8 ohm load and there is no 8 ohm match with all for speakers you can use the next value impedance greater than the limit on your amplifier. Put in values where you plan to put a speaker.
The impedance change with a parallel speaker connection is only slightly more complicated than the series connection.
