This is for those who have access to Sonion drivers.
I have some new Sonion 2389D(Dual driver). This is the best midrange and upper midrange/lower treble driver ever made period.
I recently helped my friend build a pair as a true successor to Savant.
Build
Sonion 2389D(internal parallel) + 22ohms
Knowles ED30761
same as the savant tubing and damper
U-pad
R parallel or R2 = 50ohms
R series or R1 = 3ohms
i just used google images
hot is +
cold is -
well, its balanced so polarity doesn't matter. For those who are just new to Fixed impedance attenuating circuit, the driver first interact with parallel resistor to drop all impedance peak and rising response down to flat, and then series resistor to actually compensate the impedance loss
it provides constant load to amplifier
for this circuit, this is 4db attenuation with 20.44ohms flat impedance all over the place
this works like a charm
20.44ohm resistance(its same impedance for all frequency) with ~110dB of sensitivity
Attenuation pads are amazing if damping factor is kept low. They keep the FR intact and also eats up noise, distortion etc.
They also linearizes impedance and phase plot while keeping the required impedance we want
