The Turbosound TCS218B is a dual-18" passive subwoofer engineered for permanent installation applications where serious low-frequency authority is part of the brief — medium and large worship spaces, club rooms, performance venues and high-output corporate AV environments.

Why dual-18"

Two 18" LF drivers in a tuned cabinet deliver twice the cone area of a single-18 sub at significantly higher efficiency than band-pass designs in the extended low end. For fixed installs that need authoritative reproduction of cinematic content, live worship music or full-range music programme without piling sub cabinets on the floor, the dual-18 form factor is the engineer's choice.

Engineering highlights

• Two 18" high-excursion LF drivers in a reflex-loaded enclosure
• Heavy-gauge birch-plywood cabinet for low cabinet resonance under sustained low-frequency drive
• Protective steel grille and durable semi-matt finish for installed-environment longevity
• Multiple M10 rigging points for permanent flown, ground-stack or in-wall installation
• Industry-standard 4-pole twist-lock speakON® connectors and barrier strip for distributed wiring
