Hi Ian,
A voltage divider is necessary to maintain the desired curve ( since that single 5R series resistor triggers a HF droop//fall-off while the Lpad mostly resists the HF droop )
A 10R resistor across the HF "BiWire//BiAmp" terminals with a 4R series resistor off of the plus terminal of the HF inputs will offer something like 4db of extra attenuation ( when compared to the stock 0.0db setting ).
FYI, an LPad in the front position before the HiPass circuitry ends up offering the HF amplifier a constant 14ohm load ( from say 5hz up to @ 300hz then very slowing decreasing to just under 8 ohms up around 20K ).
- a pretty safe load for most amps.
- With loud listening those added LPad resistors will get very hot.
PS; Here are some visual aids.
- Read the bottom Legend for clues as to what curves are what.
