For those who want to determine the sound pressure level change via a calculation, a generalized calculation uses the area ratios.
To calculate the sound pressure level change for any BR ports (rectangular, round,...) and woofer (round and oval) the area ratio can be used.
The calculation of the sound pressure level changes slightly
delta = 10 Log ([port area]/[woofer effective area])
