CAUTION
Signal levels exceeding 130% rated signal voltage can dam-
age the speaker. Consequently, an incorrect tap connection
may cause speaker damage. This means that if a 25V tap
is selected when a 70.7V amplifier is being used, speaker
damage may result. Therefore, be sure to select the proper
taps for the amplifier voltage/input power level combination
being used.

Two screws are included for attaching the speaker to the electrical
