A speaker physics question.

I hear you OG but if you yell hello in a cave and it hit's a wall parrallel to you it will come back. Same with yodelers in the Swiss alps so if you direct the sound in an orderly manner out of the cab instead of letting it rattle around inside you'll reinforce the SPL and eliminate that sound waves bouncing around in a wooden box sound. Here is a couple I'm working on the first one is 40W by 24D by 36H The second one is 48W by 24D by 36H. I reread what you said and I agree that the sound waves expand as they leave the source but only because they are not directed by a hard surface, For instance when people are talking in a boat on a calm lake. Even if they're way out you can almost hear what there saying because their voices are directed along the hard flat surface of the water. By loading do you mean creating some back pressure? Because I would think the basket does that to a degree on the back of the speaker.
