Vertex 6.5" In-Ceiling Subwoofer (Each)

ELAC Vertex IC-VS6-B In-Ceiling Passive Subwoofer (Each)

Designed for installs where you want real bass with minimal visual impact, the ELAC Vertex IC-VS6-B is a passive in-ceiling subwoofer built to fit between standard ceiling joists and disappear into the room’s design. Low frequencies are produced by a 6.5" dual-voice-coil (DVC) woofer in a bandpass enclosure, venting through a discreet port opening for clean, controlled low-end reinforcement.

Made for clean, modern installs

A key part of the IC-VS6-B system is its flexible port tube—easy to route during installation, yet rigid enough to help reduce turbulence and minimize port noise. The port coupling ring is designed so your trim-out can visually match ELAC’s IC-V31 small-aperture in-ceiling speakers using either a round or square grille, creating a cohesive look alongside contemporary small-aperture lighting.

Why you’ll love it

• Discreet low-end support: adds bass where floor subs aren’t practical
• Bandpass enclosure + port: strong output from a compact in-ceiling form factor
• Flexible port tube: easier routing with reduced turbulence/port noise
• System-matched option: sonically matched to ELAC IC-V31, but works to reinforce bass with other speakers too
• Round or square grille compatibility: helps cosmetically match lighting and ceiling speakers
