We talk a lot about the science behind digital audio and electronics, but not so much about acoustics. I've been working on my speaker system lately and through trial and error, I've stumbled across something that works really well, but I'd like to understand the science behind it a little better.
My system is a blend of wide dispersing speakers and more directional horn loaded speakers. I understand the stuff about on and off axis, but I'm interested in the difference in sound between a wide dispersion speaker and a directional one when hearing them on axis. My theory is that wide dispersing is best for rear channel speakers, which have to bridge a wide space to create a phantom center in the rear, and a combination of directional and wide dispersing is good for the mains which have more sound localized hard left or hard right, but still have to bridge in the middle. For center channel a highly directional speaker is good to add presence to vocals and dialogue in movies. Voices seem to cut through better that way. I'm not sure how dispersion affects room reflections. Would it be similar to the difference between focused and diffuse light? I'm also wondering if horn loaded speakers are better in specific frequency ranges (i.e.: treble) or if they work the same with lower frequencies. Would it be possible to create a highly directional subwoofer? Not sure what application that might have, but it's interesting to think about.
There's definitely a difference in sound between a directional and a widely dispersed sound. Does anyone have any good resources for web links that talk about the differences and how to apply them in sound systems?
