11 Listening Position

Just as loudspeaker positioning and room treatment can address the issues of standing waves, flutter echo, reflections, and bass reinforcement, careful attention to listening position is crucial to achieving accurate sound stage placement, tonal balance, harmonic structure, focus, and image size. In order to fully benefit from the Sentinel Active Reference System's outstanding resolving potential, one must consider the three dimensional location of the listening position in relation to the system and room.

Path Length Symmetry

In the previous chapter, it is recommended to maintain left/right symmetry in the listening room to preserve a balanced acoustic "space." Similarly, if the listening position is severely off to one side, there will be a significant difference in the path length of sound emanating from the loudspeakers. The resulting time differential will disturb the overall left/right balance and cause a phase shift in the information coming from one channel relative to the other channel. Depending on the frequencies involved, some sounds will arrive at the listener's ear to some degree out of phase and cause cancellations or drop-outs in the frequency spectrum. Therefore, it is important to maintain a listening position that is reasonably symmetric to the room and centered between the loudspeakers.

Time Alignment

The front planes of the Sentinel Active Reference System have been carefully sculpted to establish accurate driver time alignment. In Figure 10.1, notice that the acoustic centers of the drivers are situated so that the wave front converges precisely at the listener's ear. In order to achieve this convergence, it is recommended to place the listener in a comfortable chair or sofa with the listener's ear about 110 cm above the floor and a minimum of two, and preferably three meters or more from the system.
