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

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.

Wouldn't there be issues with matching to the B139 where the filter kicks
in?


I have a scan of the R50 crossovers from my old B139/B110/T27
project if you are interested.

That would be handy - I'll email you.


Why not make replicas of the LS3/5a crossover for your new boxes.
I believe they enjoyed a certain reputation once!

Indeed they did. How would they fare with a 20W valve amp? I have to say
that I am on something of a minimalist thing with this...
