I'm fine, thank you. I don't post very often on this forum but I'm always lurking.

Do you know what Xmax is, at least approximately? Is there going to be just one of these drivers in the cabinet, like for a 2-way?

Paul can you please do 2 models for comparrison? One with driver and port in ideal alignment and one with driver at one end and port at other end. I have a design that that may be more attractive but it would require the driver and port all the way at opposite ends. Thanks

I've been playing around with modeling for a B.R. In order to eliminate the dip in the mid/bass ,the volume can't be more than 1 cu. ft. and the tuning needs to be 47hz

I'll see what shakes out, but IME locating the driver at literally the very beginning of the line is seldom very good unless it's for subwoofer duty where the driver is crossed below 200 Hz.

My modeling will tell me what the tuning frequency needs to be as well as the cabinet volume. That does not mean what you've stated is incorrect, however.
