I'm in the midst of attempting to build my first ever subwoofer.
It'll be a sealed enclosure where my goal is to measure my room gain, then compensate the build Qtc to achieve the final Qtc once placed in the room.
I've read that the final Qtc can change, and most likely will change, once you place the subwoofer in the room.
Hence my understanding of aiming for a build Qtc is quite useless if the room alters the final Qtc once installed.
I think I know how to measure the room gain, a near-field and a far-field measurement, preferably at listening position and/or sweet spot, if you will, compare the two SPL results by looking at the scale.
However, what to do with the given/generated dB difference?
How do you add the difference into the build Qtc to calculate the final Qtc in the room?
Thanks, as always.
