Good explanation and it makes sense. The only point I would take issue with is the matter of smearing over multiple drivers. Assuming line array theory is properly considered, that's not a phenomenon that bears out in measurements. That becomes a problem only when the wavelengths become small enough as to cause decoupling of the drivers. It's certainly problematic in some designs. For woofers crossing over at 250Hz it's not a problem. For mid-range drivers, special care should be given to physical placement and crossover points. I'm of the opinion that arrays are basically pointless for mid-range and higher frequencies in a residential setting. I appreciate the usefulness of picking a larger drivers for mid-range duty for it's dispersion, but at the bottom of a driver's pass band they're implementation is usually omnidirectional. I'm not sure there's a replacement for a decently sorted room.
