Enter the minimum safe operating impedance for your amplifier in the white field above (this is 2 ohms per channel for most amplifiers). When you click the ; 'enter' button, the proper speaker impedance will be calculated for each configuration.

Speaker Impedance vs Power Outpu ... As we said earlier, the impedance of a speaker is its opposition to the flow of A.C. current. The lower the impedance, the higher the current flow (all else being equal). ... Most car audio equipment is designed to operate into lower impedance loads (4 ohms or less).

If you go back to our example of 8 ohm speakers, we found that a single speaker had a total impedance of 8 ohms (duh....), two 8-ohm speakers had a total impedance of 4 ohms (8/2); three speakers had a total impedance of 8/3 ohms, or 2.67 ohms, and 4 speakers totaled 8/4 or 2 ohms.

The blue line in the graph above shows the actual impedance of a speaker that is rated as "8-Ohms." As you can plainly see, at 75Hz the speaker's impedance is 40 Ohms. At around 100Hz the impedance drops to just over 5-Ohms.

A simple way to check the impedance is to measure the DC resistance of the voice coil with a Volt-Ohmeter. If it measures more than 4 ohms but less than 8 Ohms, you call it an 8 Ohm speaker. Same for the 8 to 16. For more information on Impedance or Z, see our Let's Talk Speakers Q & A page.

The power rating of an amplifier may be stated for various load impedances; the units for load impedance are ohms. The most common load impedances are 8 ohms, 4 ohms, and 2 ohms (if you have an old vacuum tube amplifier the load impedances are ... Also, tube amplifiers use an output transformer to interface to the speaker;

The frequency response of a loudspeaker system depends on how the system is "loaded" in much the same way that the output from a power amp depends on the load impedance. The power amp drives an electrical load specified in Ohms. ... Half Space = 2 pi steradians (commonly specified speaker load); If you imagine putting...

Speaker Ohms Calculator - Connect extra speakers to your guitar amp safely. ... To calculate the total impedance (Ohms) when connecting speakers in Series is straight forward, just add the impedance (Ohms) of each speaker together. E.G. If you have two 4 Ohm speakers in series, the total impedance would be 2x4 = 8 Ohms.
