Dear Ralph,
I think one 12" Phy-HP full range drive unit with twin TW37 would overcome the high frequency extension issue. What do you think?

Are you talking about the Phy-HP Open Baffle or Supravox field coil 15" in an Onken box?
I have listened to the Phy-HP Open Baffle system two decades ago but it has
coaxial drive unit on it. I can feel the bottom limited around 40Hz.
I think an low pass filter for the 15" field coil Onken bass system is necessary.
The attached diagram is for EMS (Ferin) B15EX drive unit
