I pose the following questions out of ignorance rather than doubt.
Does the Tapped horn really meet the criteria for a horn either? Especially in the case of the PB-12 and the vortex where the mouth is so small. To answer my own question I assume it is because the TH does serve as an acoustic transformer even if the mouth is too small to have pattern control?
How does the TH differ from a transmission line?
How does the tapped horn avoid the problem the old scoops had with the rear wave arriving late and causing cancellations?
Is the TH truly a new alignment or a method of optimizing an old one?
With the sensitivity being relatively high on most of the models it seems harmonic distortion should be much lower than a front loaded design, but with the drivers exposed does that mean more distortion relative to a traditional bent bass horn where the drivers are buried behind several curves?
How does the TH avoid excessive group delay and messy transient response?
How much propagation delay is exhibited by the various TH models?
Some of the spec sheets include the statement:
"Low frequency pattern control extending well below 100Hz is achieved by adding a second subwoofer. Unlike many designs on the market today the TH achieves this control without compromising output or additional signal processing expense."Is this increase simply because of more mouth and surface area or is there an additional trick?
Why is the sky blue?
Where do babies come from?
Why do we drive on parkways and park........
