The term spinorama derives from rotating the loudspeaker to gather response data

Evidence

The measured product is an Infinity Prelude MTS (ca. 2000), a hybrid design with an active woofer that reliably achieved high subjective ratings in double-blind evaluations. Its extended bass was a contributing factor. The family of curves in Figure 2.9(d) is the full spinorama—a name that has no specific origin, but which is obviously associated with the fact that the loudspeaker is rotated, “spun”, to collect the basic data set. — Toole, Floyd E, Sound reproduction- the acoustics and…, 204
