CONNEC TION & OPERATION
Low Impedance (16Ω) Connections
Low impedance models are fitted with two terminals for the (+)
and (−) incoming amplifier feed.
Speakers may be wired in parallel as shown below. Ensure
that the total impedance of connected speakers does not fall
below the minimum impedance of the connected amplifier. The
following table shows the net impedance when several speakers
(16Ω) are combined in parallel.
No. of Speakers in Parallel Combined Impedance
2 8Ω
3 5.33Ω
4 4Ω
5 3.2Ω
6 2.67Ω
7
2.29Ω
8 2Ω
70/100V Connections
70/100V Models use one terminal for the Common (−) connec-
tion and the other three terminals for the transformer power taps.
NOTE: Power taps are labeled for 70V operation. Connection
of 100V amplifiers requires use of the next lower wattage tap to
prevent damage to the speaker.
Connect speakers in parallel as shown below:
Select the power tap by dividing the amplifier’s available power
by the number of speakers to be connected. Always select the
next lower wattage tap. For example:
200W amplifier ÷ 20 speakers =10 Watts;
use the 7.5W terminal
