wow... 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

[/B]Alex, do you have any recomenndations for powered speakers ....you sound very knowledgable. Thanx

MarcK,
I don't know what the audience hears, but I agree with Donny, that the first person who must like the sound is myself - when my music sounds good to me, I can entertain my audience better, even if the audience does not know the difference between mono and stereo.
As for one-box setup, I have a Motion Sound KP100, which I am considering selling (and just sticking with my large system). The KP series of Motion Sound is designed to reproduce stereo sound from a single box (I am sure you can find many posts here on this topic). I find that my gigs are mostly in front of larger audiences, and most involve dance music, which is why I find that I am not using the KP100 lately.
The other single-box solution used to be Fender Keyboard SFX - really nice stereo separation, 160 watts. I heard it in a music store, and liked it, even though it was kind of expensive. Fender stopped making them, but you can still find them on Ebay sometimes. I have not heard anything negative about them, other than the fact that it is on a heavy side (but has wheels).
Regards, Alex
