I have a sub I built years ago with a Tumult and 4 Adire 15" PRs that has been sitting in storage until I got my hands back on it today. Frankly speaking I've always been unhappy with its performance. I'm trying to figure out why it sucks. Step one is to measure it and compare it to the predicted model. Dragging it out into the middle of a field and measuring it ground plane isn't practical. So... I can close mic measure (with REW) the driver with and each of the 4 passive radiators and then add them all together and get a reasonably accurate measurement of the sub (assuming I'm consistent with the distance between the mic and each driver / PR) right?
