Default Ported sub, do I need to combine measurement ?

I wonder , let's say i'm using REW and want to measure a TL design low freq response , do I need to combine/averaging the measurement at driver (center) and port (center) ?
Or do I measure halway both , or .... ?

thanks

1/8" away from center of dust cap and flush with center of vent. Then combine.

I'd recommend impedance measurements to find the tuning.

For LF measurement, I'd say you need to drag the box outside and run the sweeps.

Here's why: Nearfield cone measurement doesn't appear to reveal system tuning
