The XM46 has a single channel (mono) filter on a single circuit board. Each board can be configured as a low-pass filter or a high-pass filter. The high quality of components is responsible for a very good sound quality. Because of the passive design the signal-to-noise ratio is very high. The noise generated by the crossover is lower than for the electronic crossovers. The use of large ferrite pot-cores for the inductors is responsible for the low harmonic distortion levels. The circuit needs no power supply and is ideal for incorporating into other equipment, like power amplifiers, etc. We can also provide these crossovers assembled into a cabinet, with or without output level attenuators. The cabinet version has the four filter boards inside.
A filter slope of 24dB/oct is standard, but other
slopes can also be provided. Each of the low-pass and high-pass
sections can be provided with 1st, 2nd, 3rd or 4th order slope
and any xover frequency. Hi-pass and lo-pass can be the same or

XM46-A......Passive crossover board, mono high-pass or low-pass.
XM46-AA.....Passive crossover in cabinet w. level controls, stereo.
XM46SB-AA...Passive crossover in utility cabinet, 2 filters.
When ordering please specify the crossover frequency.
We have frequencies from 20Hz to 20KHz available.
The XM46SB is the same
filter, but in a small metal utility cabinet.
The size is 4.5"w x 9.5"l x 2"h . See below. The box holds two channels.
This can be for example two low-pass filters or two hi-pass filters or one low-pass and one high-pass.
Second, third or fourth order filters, high pass or low-pass , 80Hz and higher cutoff frequency.
Each channel has a 12 position level control attenuator with 1dB steps.
Fully Balanced high pass filter:
