Boom! Physics to the rescue! Of course, it matters what frequency you really want to peak when it gets to the listener - the lower frequencies have longer wavelengths (by definition), so it depends. If you want the peak at a frequency that is shorter than the reflected distance (source to back to listener) it might be better to have them facing slightly upwards, or forward from the very back, or some other innovation.Originally Posted by Huflungdung5342
In some cars (like my Pathfinder) it doesn't make much difference what you do, especially if you listen to music with varying bass frequencies. Some will be at perfect resonant wavelengths, some will be too long, some will be too short. Physics will explain it, but your ears will tell you what sounds good and what doesn't.
