Ultra-rigid Highly Oriented Polyolefine makes an ideal cone material — it's 30 times stronger than polypropylene and extremely light. Sony's XS-W1621 6-1/2" speaker features an H.O.P. woofer that reacts quickly and accurately to low-frequency bumps and surges without distorting. A built-in paper cone tweeter plays warm highs. Extra mounting tabs allow this speaker to fit a 6-3/4" opening. Grilles included.
