10B-STD, 10B-SUB and 10B-LR Crossovers Frequency/Resistor Tables
The 10B-SUB (for sub-woofer applications) and 10B-STD ("standard" for general purpose
applications) are exactly the same except for the set of crossover frequencies available via the
front panel controls. The 10B-LR, however, is a very different crossover. All three crossovers
are housed in a single rack height cabinet and all three are stereo units.
The 10B-SUB, since it is intended for sub-woofer applications, has a low frequency set
of crossover points, between 40Hz and 500Hz.
The 10B-STD, intended for general purpose bi-amp or tri-amp applications, has a much
broader set of crossover frequencies spaced between 70Hz and 4500Hz.
The 10B-LR employs Linkwitz-Riley filters (24dB/octave) and has no front panel
controls for setting the crossover points. Instead, the crossover points are determined by eight
pairs of resistors. Each pair of resistors is located on a separate programming board (10BLRPB) and each channel contains 4 programming boards. The circuitry for each channel is
located on its own crossover board, and each crossover board contains both a low pass and a
high pass Linkwitz-Riley filter. In some cases, the programming boards are dispensed with
and the pairs of programming resistors are soldered directly onto the crossover channel
boards. Since a Linkwitz-Riley filter is formed by cascading two 2nd order filters, use only the
2nd order tables in the 10B-LR Frequency/Reisistor Tables beginning on page 22 for
determining the correct resistor values.
Due to ongoing difficulty in obtaining precision polystyrene capacitors in all values, we
have had to substitute capacitor values from time to time. Therefore the 2nd order low pass
capacitors (C1a, C1b, C2a & C2b( may be either 20nF, 22nF or 24nF. Also, please note that
C1 is actually formed by paralleling two capacitors of the same value. Parallel capacitors are
also used, on occasion, to produce other values of capacitance where needed. The value of
two capacitors in parallel is equal to the sum of the two capacitances. Also note that
sometimes a parallel capacitor may be soldered to the underside of the channel board, so
remove the board (after disconnecting the power, of course) and check.
Since the crossover point of a filter is determined by the combination of the capacitor
and resistor values, altering the capacitor values slightly can be easily compensated for by
similarly altering the relevant resistor values. Therefore, there are several tables for use with
different sets of capacitors. Always check all capacitor values with those listed at the
beginning of each table before attempting to change any of the installed components.

Formulas for 2nd order LOW pass filter are as follows:
PI = 3.14159 C = 1 / (2 * PI * Fc * R)
C1 = 1.414 * C C2 = .707 * C
R = Ra = Rb = 1 / (2 * PI * Fc * C)
Fc = (1 / SQR(C1 * C2 * Ra * Rb)) / (2 * PI) = (1 / SQR(C^2 * R^2)) / (2 * PI)
Formulas for 2nd order HIGH pass filter are as follows:
PI = 3.14159 C = Ca = Cb = 1 / (2 * PI * Fc * R)
R = 1 / (2 * PI * Fc * C) R1 = .707 * R
R2 = 1.414 * R
Fc = (1 / SQR(Ca * Cb * R1 * R2)) / (2 * PI) = (1 / SQR(C^2 * R^2)) / (2 * PI)
