Galaxy Audio G-1200 - Manual (Page 8)

EXAMPLE 2 USING GALAXY HOT SPOTS:
Z= = 8 Ohms for two HOT SPOTS
16 x 16
16 + 16
Z= = 5.33 Ohms for three HOT SPOTS
8 x 16
+ 16 8
Z= = 4 Ohms (the total load)
5.33 x 16
+ 16 5.33
As long as all of the speakers have the same impedance rating, the equivalent impedance
of the system is the rated impedance of one speaker divided by the number of equivalent
speakers.
