CORE C2.20
Unleashed Authority. Built To Last.
Description
Flagship punch in the CORE lineup—the CELTO Acoustique C2.20 unleashes 2 × 1200 W @ 8 Ω (2000 W @ 4 Ω) via advanced Class TD topology for superior efficiency. Engineered for high-output installations and touring systems needing authoritative drive without compromise. Higher gain (42 dB) and faster slew rate (>30 V/µs) provide lightning transients and headroom to spare. Same proven protection and preamp circuit as siblings, now with even greater thermal stability. Linear toroidal PSU and copper heatsink cooling handle sustained high power effortlessly. Full Neutrik connectivity and flexible operating modes make integration seamless. At 19.5 kg, it's the heavyweight champion that still fits standard racks. The C2.20 delivers the kind of power that makes speakers thank you—and audiences stay longer.
