the boats are a nice touch

I thought I'd reply here instead. The short answer is, yes but I'm not sure how. I've come up with a sketchup model for that BP6 sub I mentioned in the other thread which looks a bit like a WW2 pill box
the left port is from the rear chamber, so handles the low end, and the right port is from the front chamber, and so handles the mid bass (sort of, 40-70Hz). My thinking was to have both sources of PVL arriving from as close to the same location as possible.
To peel back the layers.... red line is the rear chamber port path, blue is the front chamber
and the driver itself, a good old infinity 1260w
I'm tempted build this purely because it looks quite amusing
more realistically I'll build it to scratch an itch to see whether this idea actually works and works well for efficient delivery of TR
Plan B is just a simple, shallow, sealed box and EQ it hard. If I don't use this NF then I will then build 2 more similar boxes, put my existing 2 UXL into them and simply stack the 3 of them in the front alcove.
For those not reading the ULF thread, this is a 6th order bandpass sub which is designed to go nearfield and hence deliver maximum particle velocity in the sub bandwidth. My thinking is that this will allow me to reduce the audible output and hence avoid any thickening of the bass delivered by the main subs/speakers.
Note that I'm not concerned by the phase rotation found in a 6th order bandpass because I will design an FIR filter that corrects this so it merges with the main sub correctly.
