What enclosures and room do you have?
B139s need an enormous box to get decent bass.


The enclosures are the remains of the home-brews I acquired many years ago.
They're based on the KefKit3 - Concerto drivers, crossover and baffle, build
yer own boxes. About 14" deep, 2' wide, 3' high. I once calculated the
volume to be 135L. They also have a series of slots cut in the back (by the
original builder), which I think is probably a bad thing. The main speakers
are Kef Q Compacts, so the mid and top drivers in the old boxes are now
unused - they're just big reflex bass cabs, probably with added slotty mush.

The cabinets are the right size. Don't know how you tune the slots in the rear.
Not that it matters if you have a DSP to equalize the bass.
