"The speakers in question are horn loaded for every driver - treble, midrange and bass. The drivers are not positioned on the front baffle. The bass drivers fire into a labyrinth before reaching their horn which does not even have a front baffle. These speakers are not designed for precision time-alignment but are designed for high efficiency to emulate the volume of a live performance."
Well, there you go! I never mentioned time alignment. The horn matches the driver's acoustical impedance to that of the room while at the same time keeping the diaphragm's excursions to a minimum which is believed to reduce distortion and exponentially increases the system's efficiency. A driver's position on the baffle is always taken into account along with the crossover's design whether it be 1st, 2nd, 3rd or 4th order and if the drivers are wired in phase or out of phase and how effects step response and the ear's perception of the system's frequency response in the vertical axis which is quite audible with minute changes in the range of only a few degrees.
Regarding your assertion about time alignment Klipsch has provided a new outboard crossover available with the AL6 series that uses DSP to do just that and extend bass response another half octave if you want to bear the additional expense. Other manufacture's designs achieve their time alignment goals by angling the baffle, aligning the magnet structures, mounting the tweeter below the woofer or mid/woofer and I'm sure there are other techniques I haven't mentioned. All require that the speaker be positioned at the correct height and have the correct orientation at all axis' to be affective. You shouldn't always be so immediately dismissive.
