Yes. Sounds like the cabinet is now tuned to 25 Hz, which is too low
for the B139 driver. Hence, the curve dips badly in the 30-35 Hz area,
where it needs the port to support the active driver, and picks up
again briefly at the lower 25 Hz resonsnce before collapsing.

Yup, this is consistent with my subsequent fiddling with a design tool.
Should I be putting socks in the vents? :-)

Only if you want to *smell* the bass. Now if you used a pair of Felicity
Kendall's nickers that would be a different thing entirely.

I would need two pairs for stereo...

I usually do - I find that reflexes generally have 'loose' bass,
although this isn't inherent in the technology.

I'll take the one pair, then - could you send them in a plain wrapper? ;-)
