But surely the isobarik process ("static pressure", i.e. having two
drivers working in tandem to ease the pressure load of an infinite
baffle) is completely designed to remove this air-brick effect? I
think their difficulty to be driven was caused by much more than the
driver/cabinet 'philosophy'.
Presumably 'passiv' is a Linnism? ;)
