technially possible. it’s kind of redundant. you can do it with just two divers. it wont be true surround sound, but no headphone set is. the are all “surround” sound or simulated surround sound. they do it via time delay, because theres only two drivers. putting in 4 drivers wont work out as well, actually. the only speakers that have multiple drivers are the high end ear bud style ones for a full freq range responce.
