The Hertz Cento CS250 is a 25 cm 10 inch passive subwoofer engineered to deliver powerful low frequencies from ultra-compact sealed enclosures. It features a polypropylene cone and dust cap, a 35 mm six-layer pure copper voice coil on a high thermal resistance glass fiber support, and a compact magnetic assembly with an integrated cooling system for extended high SPL use.

The CS250 is optimized for sealed boxes starting from 16 liters and for installations that require reduced mounting depth because it lacks a rear decompression hole. It accepts common amplifiers with a 4 ohm configuration and includes a terminal block with solid push connectors that accept cables up to 8 AWG; an optional CG 250 metal grille is available for protection and finishing.
