Al,

The speed of sound is the same (depends on temperature and density) in the medium, e.g. air. The higher frequency results in shorter wavelength, and conversely, lower frequency sounds have longer wavelengths.

Donny, that writeup from Mackie is a bunch of BS. The difference in distance between the horn and bass to the front of the speaker is negligible. If anything, it would have been easier corrected by physically placing the woofer deeper inside the speaker.

In reality, when one plays guitar (or any other string instrument), the low-frequency notes are made by the entire string, while the higher ones are made by a short portion of the string. There is easily half a foot of difference between the two, but to our ear they sound pretty natural.

While you will quite possibly find coils and capacitors in the other speakers, they are used as filters/crossovers, rather than time delays.

While Mackie does use high-quality electronic components, they also use a fair dose of bull, which makes me suspect that they are not nearly as technologically advanced as they claim to be (or charge for).

Nonetheless, I hope you enjoy yours.

Regards,
Alex
