NHT Evolution System Television

C) The internal midrange chamber features non-

parallel internal surfaces that randomize stand-

ing waves, eliminating comb-filtering and

improving clarity and detail. The chamber is also

sized to the midrange driver so that it is acousti-

cally small. This further reduces the possibility of

standing waves.

D) The small footprint of the Neodymium tweet-

er allows closer placement to the midrange dri-

ver, improving mid-range coherence.

E) The tweeter is mounted to a solid aluminum

“Wonder” bar that acts as a massive heatsink,

providing high power handling and less power

compression.

F) The Wonder Bar is mounted to the tweeter

from the rear of the cabinet, further increasing

cabinet rigidity.

11.2 What is "Virtual" Focused

Image Geometry?

NHT's hallmark for many years was a uniquely

angled which we described as Focused Image

Geometry (F.I.G.). The angled cabinet focused

the mid-range and high frequencies into the lis-

tening room and away from room boundaries

increasing the ratio of direct to reflected sound.

This resulted in loudspeakers systems univer-

sally praised for their imaging and detail to a

wide listening area.

Evolution incorporates a "virtual" adaptation of

F.I.G. Rather than an angled cabinet, we

increase the energy at the listening position

using the crossover.

When Evolution monitors are vertically oriented

and the tweeters on the inside edge of the cabi-

net the null created in the crossover between

the mid and high frequency drivers is directed at

the sidewalls. The graph below shows the

decrease in energy, or reflected sound towards

the wall (C) and the compared to the direct

sound radiating at listening area (A & B). This

improves detail and provides a 3-dimensional

soundstage.
