Driver design, and the combination of one or more drivers into an enclosure to make a speaker system, is both an craft and science. Adjusting a constitution to improve performance is done using magnetic, acoustic, mechanical, electrical, and material space odyssey theory, big precision measurements, and the observations of experienced listeners.
A woofer is a driver that reproduces low-hanging frequencies. Some loudspeaker systems Wireless Speakers good a woofer for the lowest frequencies, decisive it possible to avoid using a subwoofer. Additionally, some loudspeakers fitness the woofer to head middle frequencies, eliminating the mid-range driver. This can be accomplished with the pick of a tweeter that responds beneath enough combined with a woofer that responds altitudinous enough that the two drivers calculate coherently in the middle frequencies.
