When merging nearfield woofer and nearfield passive radiator, are you looking to match up the bottom ends of the tails like you would with a port merge?
The reason I ask, is I am taking both measurements 1/4" from the cone, but I am having to adjust the PR response up almost 4dB in order to get the tails to match.
First pic, nearfield of woofer and PR, a copy of the PR raised to match the tail of the woofer.
Second pic, summation with matching tails.
Third pic, summation with no level matching.
I know I need to add mass to the PR, but before I start those trials, I would like to make sure I am summing them correctly.
This is to be merged with the farfield of the woofer for use in a two way crossover.
