I suppose the idea behind time corrected speakers is that each frequency arrives at the listener's ear at about the same time. I suppose we could move the subwoofer(s) into the next room. Inconvenient and peculiar.
2x6, the
speed of sound is independent of its frequency. In still air, like that found indoors, the only thing that can affect it is the ambient temperature and humidity. Some crossover designs can alter the phase of sound differently depending on the frequency, so time correction is important in that aspect. Outside of the speaker's cabinet, however, the only thing that needs to be done is to keep the drivers as close to equidistant from the listener's ear as is reasonable.
