    Crossover for BMS 4540ND

    Does anyone have schematics for BMS 4540ND (anywhere from 1200hz on up) for a 2 ways setup. I can tune my low frequency drivers to match the 4540nd. Thanks.

    The only usage of the BMS4540 on this board with a passive crossover is in the three way Isiris system, used with a DDS waveguide. Note that due to the complex impedance of a horn driver and waveguide within the driver operating range, a muli-part zobel is recommended for a passive crossover, otherwise the impedance variations put ripples in the frequency response.
