416 or 515 for my new front loaded horn design? Help Please

[atilsley]

Do you like blondes or redheads? I prefer the 416B. Your mileage may vary.

With the lower Fs of the 416, I'm leaning towards this model so it can provide a low bass response, aka Model 19....but want to ensure I'm not giving anything away for the front loading aspect....which is really the primary purpose of this personal project.

Regards
