then figure the length of that freq.( 1000 hertz being I think
1.3 feet) your goal is to phase match rarefaction with compression.
so I'm guessing you would need a larger port to not produce phase issues
but being low freq's it is much easier to not have phase issues being that the big
freq's are much stronger than the little ones .

with all that curvy **** it looks like you might make a fine whistle
with your phase unless you figure out how to phase the whistle

but then again if you figure out how sound bounces, meaning the time speed and angle and time it takes for the sound to turn around from
a stop or angle.

you know even if you did this it would really be good for one freq
and possibly it's multiples

but then again what do I know

maybe if you added multiple ports expressing each freq. and their multiples it might work

the only sub I have ever been impressed by was the blue sky
the only thing that impressed me was the fact that it was barley on

but then again I have not heard to many pro subs.
