See www.aes.org and look for papers by Floyd Toole. The NRC is Canada's National Research Council. Dispersion is important to tonality as well since it involves the speaker's power response.
Differences can be heard and it doesn't take a golden ear audiophile to be able to appreciate it. Actually most commercial arrays are far more expensive than what we charge and our kits are about the same cost as what you would pay to Madisound or Parts Express. It takes some $ to make a decent array and unfortunately too many builders try to do it really cheap and end up with a bad sounding speaker. Too many posts start with "I bought all these XYZ drivers for a few dollars - how can I make a good line array?"
