FCS21P-V3 2500W Active Sub $1995 Each
The Freq City Sound FCS21 redefines what’s possible in low‑frequency performance. Engineered for demanding stages and large venues, this 21‑inch active subwoofer delivers powerful, punchy, and full deep bass that stays smooth and controlled — from tight club mixes to massive outdoor festivals.
With 2,500 watts RMS of Class‑D power, the FCS21 moves serious air while maintaining clarity and musicality. Its output is fast, even, and accurate, ideal for reproducing the full impact of kick drums, bass guitars, and synth low‑end with effortless authority. The built‑in DSP has been meticulously tuned by Freq City Sound engineers (each with a “black‑belt in Smaart”) to get the most out of the enclosure right out of the box.
The result: chest‑pounding output that’s clean, detailed, and precise — performance you can trust night after night.
