Well, the size box I was using was the one Mike P built...hopefully he can chime in.
I also modeled it as a member on another forum suggested...slightly larger box (14.2cuft) and lower (11.5Hz)...results in a 36" port that's 6" in diameter. For that configuration, a velocity of 17 is reached at about 15.5Hz, and the port velocity increases STEEPLY as the frequency goes down.
So...over what frequency range should I target port velocities < 17? Is it important throughout the frequency range, or only above some value (like 15Hz)? My apologies for the questions that everyone else probably already knows the answer to...
