Manual abstract:
Tweeter dispersion pattern in the crossover region. 90° 110 100 90 Sound from Speakers 80 70 60 50 40 30 20 10 20Hz 50 100 200 500 1K 2K 5K 10K 20K Figure 4. On- and off-axis frequency response of a conventional component system. When we listen to speakers, we hear a combination of the sound that comes directly from the speaker (the on-axis response) and the off-axis response, which arrives at our ears after being reflected by boundaries and other objects in the room. In large rooms, the walls and other objects are often located several feet from the speaker enclosure, so the intensity of the reflected sound is lower than that of the direct sound. In rooms, the direct sound in the "listening window" dominates the sound we hear. The off-axis sound is a secondary but important part of the overall sound of the speaker (see Figure 5). In cars, the boundaries are much closer to the speaker and to the listener, so the intensity of the reflections is more similar to the intensity of the direct sound. Additionally, the reflective surfaces in a car are so close that our brains can't distinguish between the direct sound and much of the reflected sound. Reflections contribute greatly to the quality of the audio experience in cars. Since it isn't practical to change the overall shape or size of the car to minimize the effects of the reflections, closely matching the on- and off-axis responses of the speaker system can help to ensure a smooth and balanced sound (see Figure 6). Reflected Sound Figure 5. Reflected sounds are attenuated at the listening position because the boundaries are far from the speakers and the listener. Reflected Sound Sound From Speakers Figure 6. The intensity of reflected sounds in a car closely match that of the direct sound, because the boundaries are close to the speakers and the listeners...
