The 355 is equipped with one 28-mm soft-domed tweeter, improving the perception of transients and other micro details in the audio, one 3-inch ATC soft dome mid-range driver which combines high sensitivity with extremely low distortion, and two 15-inch low-frequency TAD direct radiating woofers, each featuring a cone diaphragm made of a tough and lightweight material that is capable of withstanding high amplitude levels without deformation.
