Biamp Community IS6-218 Medium Power Dual 18-Inch Subwoofer (Black)...
Product Overview
The Biamp Community IS6-218 is a passive dual 18-inch installation subwoofer for low-frequency reinforcement in permanent sound systems. Part of the I SERIES Subwoofer 600 family, it provides deep, high-output bass for houses of worship, auditoriums, and large multi-purpose venues. This sub-bass loudspeaker integrates into flown arrays with matching I SERIES full-range models for cohesive system design.
Product Description
The IS6-218 is an I SERIES Subwoofer 600 dual 18-inch passive installation subwoofer rated at 1400W continuous (4 ohms). It is well suited to venues from houses of worship and auditoriums to arenas and themed entertainment where extended low-frequency reinforcement is required. Each cabinet is engineered with matching heights, face widths, and suspension points for integration into flown arrays alongside I SERIES full-range models. The IS6-218 is a direct-radiating subwoofer with large, balanced ports that optimize enclosure tuning and distribute air pressure evenly across the cones, reducing distortion and extending system longevity. Long-excursion ferrite LF drivers with FEA-optimized motors and symmetric-movement suspension provide deep bass. Drivers are loaded into individual air volumes within the enclosure, isolating their performance and allowing directional subwoofer techniques such as steered end-fire and cardioid patterns within a single cabinet.
Key Features
- Dual 18-inch ferrite LF drivers — Long-excursion drivers with FEA-optimized motors and symmetric-movement suspension deliver deep, controlled low frequencies.
- 1400W continuous power handling — The subwoofer handles 1400W continuous (5600W peak) for high-output bass reinforcement.
- Single or dual amp operation — The IS6-218 can be driven single-amp at 4 ohms or dual-amp at 8 ohms per driver.
- Isolated driver air volumes — Separate internal air volumes enable directional steering techniques and add driver protection.
- Flown array integration — Matched enclosure size and aligned suspension points allow seamless integration with I SERIES full-range models.
- High sensitivity design — High sensitivity minimizes power compression losses and reduces required amplifier size.
Typical Applications
- House of worship
- Auditorium
- Multi-purpose room
