Ths S622TR's 6-1/2" polypropylene cone woofer provides impressive bass, while its 1" silk dome tweeter (mounted in an acoustic back chamber) has smooth and extended performance. Both the woofer assembly and the tweeter pivot to direct sound at listeners for clear sound, even with less-than-ideal placement. The RotoLockÆ mounting system makes installation quick and easy and a perforated aluminum grille allows the speaker to blend into the decor.
