Maximizing Performance of Loudspeaker Ports
Too abrupt a change in velocity still leads to losses. Optimally, the flare rate should minimize turbulent eddy formation and early boundary layer separation is what I gather from it. You didn't mention if you were talking about ports or not, but I still figured you could gather information from that paper.

Cubic expansion laws are generally pretty good for nozzles, although a speaker makes a different than normal boundary condition. But you want to know your Reynolds numbers, albeit we want them low. So "low Reynolds number nozzle design" will give you a few NASA/NACA papers for your consumption.
Do you have a CNC to fabricate the nozzle is the better question! Otherwise, probably okay to use the off the shelf ones.

I didnt mention a port, but yes I need the info for ports too! I'm designing a Skram like subwoofer, and I'm looking into all the ways to optimally design the vents AND horn mouth. Thanks for the link!
