Isobaric (most commonly “push-pull”)

An enclosure that uses two woofers mounted face to face, one wired reverse polarity.  This alignment effectively cuts the vas in half.  The general rule of thumb for an isobaric enclosure is twice the woofers, twice the power, and half the box size3.

Pros: Very small enclosures, increased power handling, driver non-linearities canceled out (lower distortion).

Cons: Very low efficiency, due to the small size of the recommended enclosures for our woofers an isobaric alignment is not practical.
