The Stylus 470s are also coated in a UV-resistant PolyGlass enclosure, making them completely weather-resistant.
It is the Stylus 470's 7 1/2" cone bass/midrange driver which gives it its lower 75Hz low end (the Stylus 370, by comparison, has a 6 1/2" cone bass/midrange driver which provides it with an 80Hz bass end). The 1" dome tweeter that gives the Stylus 470s their high end is the same high-frequency driver that is present in each of the speakers in the Stylus line. The Stylus 470 outdoor speakers are available in black or white.
