It feels pretty good when the driver mfg'er backs you up
I was actually thinking that 2 boxes would be better anyway. That way they are lighter and you can be more flexible with placement.
What kind of enclosures do you want to do? MDF boxes, sonotubes, or maybe even something else? If you didn't want to bend the ports you could go with a sonotube design. You could go with a slot port too.
