that its smoothest response was 15
degrees down from straight ahead (aimed
right at the listener’s knees!), all because
you didn’t pay proper attention to lobing
behavior.
We all know that speakers lobe. So why
not take advantage of that fact instead of
fighting it? That’s what our exclusive
Directional Vector Control (DVC™) does.
By flipping the DVC switch to “on,” we
electronically manipulate the crossover so
that the speaker’s midrange output lobes
down about 15 degrees from the speaker.
This is perfect for when this speaker is
mounted above ear level and you want to
use them for front-channel LCR duty. The
midrange sounds—which determine
directionality and intelligibility—are directed
down at the seated listeners’ ears, even
though the speakers are six or seven feet
above the floor. The following graph shows
the measured response of this speaker at
the listening position; red is DVC off, blue
is DVC on.
Therefore, between the low crossover point
of LRT and the up-down midrange lobing
of the DVC, we’ve engineered a speaker
that covers the listening area more
effectively, without the drawbacks and
compromises of ordinary high-crossover
pivoting tweeters, and without having to
resort to the expense of a three-way
design.
We’ve also included a Boundary control to
compensate for the upper bass/lower
midrange buildup that occurs when a
speaker is mounted near a ceiling or wall
boundary, and there’s a three-position HF
level control to adjust tweeter level for
varying room acoustics.
