MartinLogan pmn DISPERSION INTERACTIONS

Your Clarity launches 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 5). 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 spectral domain. Consequently, small refined

adjustments can result in noticeable sonic improvements.

As you can see from the illustrations, your Clarity speakers

project a controlled dispersion pattern. Each Clarity is a

26” inch line source beginning 25" inches above the base.

This vertical dispersion profile minimizes interactions with

the floor and the ceiling (see figure 6).

Due to dispersion limitations of small electrostatic panels,

your Clarity loudspeakers are equipped with NAC (natural

ambience compensation) drivers 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

unnoticeable. Listeners sitting off-axis outside of the listening

window will find that high frequencies are accurately ren-

dered and comparable to those provided on-axis by the

Clarity’s ultra-precise electrostatic driver (see figures 7 & 8).
