The toroidal inductors are wound on
powder metal circular cores. These inductors are much smaller
than air core inductors and better than traditional iron core
The capacitors are polypropylene.
There is provision for on-board attenuators to equalize tweeters
and woofers with differing sensitivities. For example it the
tweeter has a sensitivity of 94 dB and the woofer is 90 dB, a 4
dB attenuator can be installed in the tweeter line.
We can make these for frequncies of 1000Hz and up. The power
rating depends on the frequency. At 1KHz the rating is50W, at
4KHz it is 100W, at 16 KHz 200W.
Dimensions of the board are 6.5" x 6.5"
Please specify crossover frequency and speaker impedance when
We can also build custom crossovers like the one below.
This one is the
XM47-2AA, 2 way stereo
passive crossover. It has large powder-iron core inductors,
polypropylene capacitors and speaker L-pads.
Unit shown below has 100 Hz crossover point for 8 Ohm speaker
and power rating of 100 W.
