Yes if that is what I need to do.Are you asking me how to calculate -5dB of voltage in reference to 2.83V?
btw, when external data is being imported, from like a measured speaker incl baffle, don't only forget to select the right important data (infinity baffle), but also disable "diffraction at baffle" (disable all, so top, bottom, left and right) at the "baffle and position" tab.
Otherwise you will get bafflestep and other things on the data you already have.
