The sensitive inner portion of the cone features a steep angle design that aids in its performance. The outer edge is flat and stiffer, producing more potent mid-bass frequencies that radiate evenly throughout the listening environment.\u003c\/li\u003e\n\u003cli\u003eThe voice coil is designed to be very light to easily achieve the highest frequencies while remaining durable enough to handle high power.
