If you are going to bi-amp, it makes much more sense to design the
crossover to go before the amplifiers - it's much easier to produce
filters using ICs than large inductors and capacitors.
3-way speaker, but two amps. I'm considering a cabinet which will roll off
the mid naturally, so no low-end cut, just a mid/top crossover. The bass
would have some kind of filter before the amp.
That doesn't sound like a very good solution.
Better to use an active crossover (4th order Linkwitz-Riley) before
the poweramps and make the B110 have a flat response down to
an octave or so below the crossover frequency.
I have a scan of the R50 crossovers from my old B139/B110/T27
project if you are interested.
Why not make replicas of the LS3/5a crossover for your new boxes.
I believe they enjoyed a certain reputation once!
