The ELAC Vertex In-Ceiling Passive Subwoofer delivers powerful low-frequency reinforcement in a discreet architectural design that integrates seamlessly into modern interiors. Engineered to fit between standard ceiling joists, this passive bandpass subwoofer features a custom 6.5-inch dual voice coil driver capable of producing impressive bass performance from a remarkably compact enclosure. A flexible yet rigid port tube minimizes turbulence and unwanted port noise while allowing versatile installation options. Designed to pair perfectly with the Vertex IC-V31 in-ceiling speakers, its trim-out system supports both round and square grilles, enabling a clean visual match with contemporary small-aperture lighting. Ideal for distributed audio and home theatre applications, the Vertex In-Ceiling Passive Subwoofer provides impactful, well-balanced bass without compromising room aesthetics.
