WF-LP:
In addition to functioning as a selectable low-pass filter, this section also provides part
of the phase correction and response compensation of the network. By shifting the
phase appropriately within the crossover region, it is possible to achieve “phase link-
age” with the tweeter, producing a seamless blend or transition between the two drivers.
This relationship is affected by the distance and angle of both drivers relative to the
listener, but also by their proximity to each other. Since in this case, most of the manipu-
lation of the overlapping region is being done in the tweeter high-pass filter, less varia-
tion of the woofer low-pass is necessary. Subsequently there are basically two possibili-
ties for the LPF:
• LP1 = low Q 1

L4 = 0.39mH
SIGNAL LINK:
The signal link jumpers provide a parallel connection between the input sides of the two
terminal blocks, allowing a single input connection to be made without the use of extra
terminals or wiring.
Caution:
These jumpers
must be removed when used in a bi-amp configuration to prevent
possible damage to amplifiers.

TW LEVEL:
In general, this section provides precise level adjustment for optimum performance or
personal taste. However, it also allows for “tilting” of the filter frequency response in
order to compensate for the natural high frequency roll-off associated with off-axis lis-
tening angles. In other words, tweeter level jumper selection will have a specific effect
upon both Q and cut-off frequency of each high-pass filter configuration. This effect can
be seen in the filter transfer function graphs for the various system types. If the TW-HP
section is set to bypass in favor of an electronic crossover, the off-axis feature will no
longer function, but basic level adjustment will still be possible.
