Vertical standing waves are a phenomenon that occurs in
nearly all speaker enclosures. Responsible for uneven,
boomy or sucked out bass response, vertical standing
waves generated inside tall fl oor-standing cabinets are
extremely diffi cult to control. But not for Pioneer. We
have developed unique acoustic simulation technology,
ABD (Acoustic Balance Drive), which allows us
to calculate the infl uence of the cabinet's vertical
standing waves on the speaker frequency response,
taking into account bass drivers and port locations.
Using this software, the port and bass drivers of
the EX Series are placed in the best position
to cut this infl uence to a minimum. This new
technology allows the fi rst vertical standing
wave to be totally canceled and the infl uence
of the second one to be signifi cantly reduced.
The result is precise and dynamic bass with
no low midrange coloration.
