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.
