You have identified the tricky parts -the transistion between the front and back horn as well as the throat of the front tractrix horn. A one to one throat with the front horn works best with my coaxials and a short 1.25" straight 'ring' at the throat is required to improve the lower end of the front wave response by a half octave. The back chamber is tricky and in my system I find a tapered transmission line with 7 liters of volume lined with felt to a 560 cm2 round throat and the back horn is quite enjoyable. Maintaining a near point source with 105 db sensitivity 50-16k was the goal. The coaxial is the Beyma 15DX. It is OK as a direct radiator but when properly horn loaded it blossoms
Bass below 60 cycles? The front mono hornsubs are also used with nearfield direct radiator stereo subs placed to the sides and behind the main listening area. The side subs are delayed and driven with their own amplifier. Setup correcty (not too difficult) the room sound much larger in the bass and the low end matches the rest of the system in sheer size and power.
