LOW IMPEDANCE (8
Ω
) CONNECTIONS
Low impedance models are fitted with two terminals for the (+)
and (-) incoming amplifier feed and two terminals paralleled to the
next speaker.
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 are
combined in parallel.

70/100V CONNECTIONS
70/100V Models use one terminal for the Common (-) connection
and the other three terminals for the transformer power taps. Note
that the Q4T offers taps at 15W/7.5W/3.75W (below left) while
the Q5T offers taps at 25W/12.5W/6.25W (below right).

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. See chart below.
