With my limited crossover knowledge I am unsure...
Not only would it change the impedance wiring them together, but the reason most only use a single woofer is that the woofer is not only doing bass duty, but midrange (up to 1.2khz) as well. basically, the sweet spot is dead center between the compression driver and the center of the woofer. the XO helps to voice the two together so that single point, is the point source. If you add another driver either above the horn or below that other woofer, then it changes that reference point completely, thus changing the XO schematic completely. Does this make sense?
Eessentially, the benefit of the danley synergy horns is ALL frequencies being reproduced are all coming from the exact same horn, and that is why they sound so good. With a horn woofer combo like this, you are getting the next-best thing to a full on point source, but since the midrange is still being done by the woofer, doubling that sound source to two different locations is a no-no for some, inluding myself.
A 2.5 way design where you do both drivers below the horn, one doing midrange duty AND bass, and then the lower one doing just the bass duty. Still requires changing the XO, but can be done. What is the benefit? A little higher sensitivity down low.
A larger horn with a 2-way compression driver that could potentially get down into the 3-400hz range therefore not requiring as much directivity out of the woofers, but go ahead and drop $700 on a 2 way compression driver, one for each speaker, and you are already at $2100, not including anything else...You first!! haha.
