CX 100


Product Description

CENTO 4” Pro

100 (4) mm (in.) | Coaxials | 120 W | 4 Ohm

Coaxial loudspeakers represent a major design challenge due to the critical nature of their acoustic output, being installed in an OEM placement often unfavorable to reproduction. For this reason, in order to achieve high performance, a great engineering effort was put into place, promptly addressed by our R&D team. The Cento two-way coaxials CX 100 features the new 24 mm (0.9 in.) Tetolon® dome tweeter that delivers a more musical and detailed sound compared to the more traditional plastic materials. The dispersion has been optimized for off-axis listening. The  SPP-M cone (Semi Pressed Paper-Mica) ensuring superior acoustic and damping characteristics.
