Can BassBox Pro measure the response of a loudspeaker?
No. BassBox Pro is not a measurement system. It is a speaker box designer. It models or predicts how an open-back driver will perform in a box with a focus on its low-frequency response. It does not model sealed-back drivers like tweeters. It also allows the frequency-domain portion of acoustic measurements of drivers and listening spaces to be entered or imported to augment the accuracy of its Thiele-Small model.
