Above shows what is possible (more or less) in terms of pressure. It shows the horn will not provide pressure below 50 cycles. And this is likely to be true. It will not magically appear out of nowhere. This does not exclude possibility that in some rooms due to modes it might sound full till 40 Hz. But 17 never ever.  


Hey Josh, what space have you simulated this horn radiating into?  I ask because they are obviously designed to be fired into corners and the walls/ceiling used to further load the driver and extend the horn: another fold if you like.  You may find that a 20Hz quarter mouth horn such as this one may get lower than 50Hz when it is loaded into pi/2 space.
