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
