The Genelec 7040A is an active studio subwoofer from the 7000 series of Genelec, designed for precise low‑frequency control in small and medium‑sized studios. Unlike monitors such as the 8040B or 8050B, this is specifically a subwoofer — it doesn’t reproduce the entire spectrum but covers the low‑frequency range, working in conjunction with main monitors (for example, the 8010A, 8020A, etc.) in a 2.1 system.
