MartinLogan E2 - Manual (Page 26)

The passive high-pass settings can be adjusted by changing
the red and black jumpers found in the high-pass section of
the ESL/Transition tower passive crossover.
WARNING! Before changing the passive-high
pass options be sure to turn the amps off and
unplug the Statement e2 ESL/Transition tower.
The design of these jumpers accommodates different lis-
tening distances to the speaker (distance between listener
and speaker). The unit is shipped in 15ft mode. If the user
is only 10-feet away the jumpers need to be changed.
The jumpers are located near the side of the crossover
located in the ESL/Transition tower bases (see figure 54).
There are red and black jumpers that are either connected
or not connected through the screw terminal block (see
figure 56 & 57).
WARNING! Never connect the red wires to the
black. wires.
The 4 options are (from least output to most output):
10-Foot Mode (figure 58)
—Red not connected and black connected.
—0dB
All-Closed Mode (figure 59)
—Red connected and black connected
—200Hz–300Hz +1dB
All-Open Mode (figure 60)
— Red not connected and black not connected
—3dB peak at 300Hz
15-Foot Mode (default—(figure 61)
—Red connected and black not connected
—200Hz–300Hz +1dB
—3dB peak at 300Hz
Figure 55 demonstrates how these different settings effect
the frequency response.
Note:
— The ten-foot mode has been set to 0db.
— The all-closed setting raises the output from 200Hz to
700Hz by 1db
— The all-open setting adds a peak of 3db around 300Hz
— The 15-foot mode adds both of the above changes
