I think it is about right. The 6C33C for upper base has 100K
biasing resistor and 20K to ground in Lpad. That would make ~60Hz. This high
pass that unload the LF from the horns that it can’t handle is very important
as you do not want driver to pressurize the horn by sound that could not be
passed by horn. You need to go with high resolution RTA and plot a low knee of
the horn decay, full range. Then you need to get the filter and run it just to
be barely visible at the plot. Then drop a half of the octave and it would be
your crossover point.Rerurn to Romy the Cat's Site
