Use all the same type in your system.

Speaker wiring 70 volt transformer systems. Attached to each speaker in a 70v system is another transformer that transformers are wired in parallel across the amplifier output making wiring simple 1 connect your speaker wiring to the common and 70 volt output terminals on the distribution amplifier. Some advantages of 70 volt systems. A step up output transformer in the amplifier provides the high 70v output signal.

A 70v output is available on bogen amplifiers and is the primary type of output for paging systems. An 8 ohm secondary connects to the speaker and the multi tap primary connects to the 70v or 25v amplifier output. No changes to the power taps on the speaker transformers are required. The transformer in the 70v amplifier is designed such that the voltage from the amplifier is greatly increased in the secondary usually 70 7 volts at maximum but the current is greatly reduced.

The t725 can be tapped at 4 2 1 1 2 1 4 and 1 8. All speakers with step down transform ers rated for 70v systems are connected to this output. If a system has a 100 watt 70v amplifier and more speakers are added so the load is greater than 100 watts the next larger amplifier maybe a 70v 150w amplifier can be used to replace the 100w amplifier.

Because the speakers tend to be fairly far apart phase of the individual speaker is not. These use the same concepts however they use 100v transformers instead of 70v transformers. You don t need to work out impedance. Other output types 25v 16 and 8 ohm.
