Why don't you like bandpass? FLH = BP4 with a flared port. TH = BP6 with dual flared ports.

I will, and thank you again Sir

It's the traditional 4th, 6th, 8th type bandpass I don't care for. I prefer stuff with a little flare flair.

Pressure on the cone is a much more complicated story than just compression ratio. Any cabinet design that increases the efficiency of a cabinet is increasing the coupling between the air and the driver, which is going to generate higher cone pressures.
That is true, the grater the loading the higher the pressure, which is key to efficiency, and no, it's not all about the compression ratio, but it never hurts to consider keeping it as low as possible given driver lifetime and in extreme cases even distortion.

What is of greater importance is how even you spread the forces on the cone, to me it seems pretty straight forward that a symmetrical dual path design will show a more even cone loading then a single path one, all else being equal, and the forces themselves are not dangerous unless you limit the excursion at the cost of proper cooling.

All I know is I prefer the sound of BP4 or BP6 over sealed and BR. I'm tired of the sealed 2-15's in my truck now. I want 6-8's or 8-6.5's in a BP4. I had 4-6.5's in a BP4 in my previous. My son has that box in his apartment at University of Cincinnati.

BP1Fanatic being a BandPass Fanatic is an obvious observation
