Your Sequel II'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 1).
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
and, consequently, small refined adjustments can result
in noticeable sonic improvements.

As you can see from the illustrations, your Sequel II
speakers project a controlled dispersion pattern. Each
Sequel II is a four foot line source beginning two feet
above floor level (See Figure 2). This vertical dispersion
profile minimizes interactions with the floor and the
ceiling.
Figure 1 Figure 1 Figure 1 Figure 1 Figure 1. Martin-Logan Sequel II's deliver a 30 degree wave
launch dispersion pattern distributed horizontally.
Figure 2 Figure 2 Figure 2 Figure 2 Figure 2. Your Sequel II speaker system is a 4 foot line
source when viewed vertically. Actual height above the floor
is from two to six feet.
