floor or the ceiling. No deleterious interference from these surfaces is created (as in virtually all other kinds of speakers).
Another advantage of the line source is that the vertical spectral content of music is virtually the same throughout the length of the line source. Hence, the seating height does not matter with this speaker; unlike point source speakers where it is important for the ears to be aligned in relationship with the tweeter.
A third important advantage of a line source is that it attenuates at
For example, with a sensitivity of 91dB/watt at 1m, the Genesis 2 is about average for large loudspeakers. At 2m, the G2 line source can deliver 89dB/watt, at 4m 86dB/watt, and at 8m 83dB/watt. For the equivalent point source loudspeaker, it will be 85dB/watt at 2m, 79dB/watt at 4m, and 73dB/watt at 8m. Hence, for a listening distance of 4m (about 12ft) the line source will appear to be almost twice as loud as a point source loudspeaker. This is the great advantage that a line source loudspeaker will have over a point source loudspeaker in a large room – particularly when the seating distance is over 4m from the loudspeaker.
The second great advantage of the line source over the point source is that the change in loudness is much less over a small change in distance. Hence, it results in a much larger sweet spot as small side to side changes in seating position result in less of a sonic change than with the point source loudspeaker.
The Genesis 2.2 is also a dipole radiator. The midrange and tweeter drivers are mounted on a rigid acrylic panel with no enclosure. This has two advantages: firstly, it eliminates any enclosure or boxy colorations caused by cabinet vibrations or resonance.
Secondly, the dipole creates a cardioid radiation pattern (like a
Hence, in conjunction with the line source, the G2.2 has no first reflection from the floor, ceiling or sidewalls. The net result is that
