MartinLogan Aeon i [11/24] Nac dispersion

Dispersion Interactions 11

Your Aeon i’s launch a 30-degree dispersion pattern when

viewed from above. This horizontal dispersion field gives a

choice of good seats for the performance while minimizing

interactions with side walls (see figure 7). Make sure both

speakers stand exactly at the same vertical angle, otherwise

the image can be skewed or poorly defined. The wave

launch of both speakers is extremely accurate in both the

time and the spectral domain. Consequently, small refined

adjustments can result in noticeable sonic improvements.

Controlled Vertical Dispersion

As you can see from the illustrations, your Aeon i speakers

project a controlled dispersion pattern. Each Aeon i is a 37-

inch line source beginning 17.5 inches above the base.

This vertical dispersion profile minimizes interactions with

the floor and the ceiling (see figure 8).

NAC

Dispersion

Due to the dispersion limitations of small electrostatic panels,

your Aeon i loudspeakers are equipped with NAC (natural

ambience compensation) circuit to fill in off-axis high-fre-

quencies. When the NAC is active, listeners sitting on-axis in

the listening window will find the effects of the NAC virtually

unnoticable. Listeners sitting off-axis outside of the listening

window will find high frequencies accurately rendered and

comparable to those provided on-axis by the Aeon i’s ultra-

precise electrostatic driver (see figures 9 and 10).

vertically. Actual height above the base is from 17.5 inches to 55.5 inches.
