The following adjustments are made using the above procedure:

sysTem orienTATion

As described earlier, the loudspeaker’s two low-frequency drivers 
operate over different frequency ranges. For proper stereo 
imaging, it is necessary that the midrange woofer (LF2) be in the 
inboard position (closer to the other speaker). The proper setting of 
the system orientation jumper bars can configure a single Project 
Everest system as either a “left” or “right” system. It is necessary 
that both bars be set in the same position. Improper sound will 
result from staggering the bars. The bars select which woofer 
receives the low-frequency signals and which woofer receives 
the  midrange  signals.  One  system  should  be  set  to  “left”  and 
positioned as the left speaker. The other system should be set to 
“right” and positioned as the right speaker.

hF drive/LF drive

These jumper bars allow you to set the loudspeakers for normal 
operation (using a single stereo amplifier or pair of mono amplifiers) 
and bi-amp operation (using two sets of stereo amplifiers and an 
external dividing network). The shorting bars are set at the factory 
for Normal (single-amplifier) operation, so move the shorting bars 
only if you are bi-amping the loudspeakers.
