Use n a for unused speakers in this calculator. The total impedance will be calculated for the entered speakers. Constant voltage speaker systems refer to networks of loudspeakers which are connected to an audio amplifier using step up and step down transformers to simplify impedance calculations and to minimize power loss over the speaker cables they are more appropriately called high voltage audio distribution systems. You will also notice the astounding distances that 70 volt distributed systems can go. In this case we show three values of loss.īoth entries are numeric. Sum all of these power taps and ensure the amplifier s wattage rating is not exceeded. The click on calculate for the required power calculation.

11 0 5 db 21 1 db and 50 3 db for 4 and 8 ohm speaker impedance. To use it enter the quantity of speakers the the wattage power tap used. Total amplifier power is reduced due to impedance mismatch.

Remember calculations are only to be used as a guide. On my side i am trying to calculate the impedance of a ceiling speaker tannoy cvs6 on which the rotary switch shows 70v and 100v and at certain positions the dots on the speaker indicate both 70v and 100v half power. 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. Speaker Impedance Power Handling And Wiring Amplified Parts Speaker 8ω speaker 8ω ω 4 70v 25v com speaker 8ω speaker 8ω 8 ohm series parallel speaker system wiring examples note that polarity is important amplifier output 8ω 4ω 70v 25v com result.ħ0v speaker impedance calculator. The voltage is constant only in the sense that at full power the voltage in the. Select the correct tap setting for 25v 70v or 100v speakers based on the wattage required to produce the desired sound pressure level for your application allowing for some additional power headroom.
