Room Acoustics and Dispersion Interactions

Controlled Horizontal Dispersion

Your Quests launch a 30 degree dispersion pattern when viewed from above. This horizontal dispersion field gives you 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.

Controlled Vertical Dispersion

As you can see from the illustrations, your Quest speak- ers project a controlled dispersion pattern. Each Quest 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. Martin-Logan Quests deliver a 30 degree wave launch dispersion pattern distributed horizontally.

Figure 2. Your Quest speaker system is a 4 foot line source when viewed vertically. Actual height above the floor is from two to six feet.
