Driver Complement
Driver complement describes the types, sizes and arrangement of sound-producing drivers in a product.
It provides more detail than a total driver count. Different drivers can cover different frequency ranges or share part of the same range.
Driver Complement — Loudspeaker
For a loudspeaker, the complement identifies components such as woofers, midrange drivers and tweeters in one cabinet. Several drivers can serve one frequency band, so their number need not equal the number of ways.
Compare each driver’s role and nominal size rather than treating a larger total as an automatic improvement. A passive radiator is not an electrically driven unit and should remain clearly identified. Keep a single cabinet’s complement separate from the total across a stereo pair.
Driver Complement — Headphone
For headphones, driver complement describes one earpiece. It can identify one full-range driver or several drivers using the same or different transducer technologies to reproduce the signal.
Compare the per-earpiece arrangement and the role of each driver. Do not double the count to represent the pair or assume several drivers are necessarily separate audio channels. The complement alone does not describe frequency response, crossover quality or how consistently the earpiece fits the listener.
