Tannoy CVS 801S LZ 8" In-Ceiling Subwoofer Loudspeaker for Installation Applications - Low Impedance Operation Only

$0.00

The Tannoy CVS 801S LZ is a high-performance, low-impedance (8 Ohms) ceiling subwoofer engineered for professional sound systems where superb audio quality and deep bass are needed. It is ideal for background and foreground music in a variety of installation applications, including restaurants, hotels, houses of worship, and retail environments.

This model operates solely in low-impedance mode, connecting directly to an amplifier without the need for a constant voltage transformer. The subwoofer features an 8-inch polypropylene long-excursion driver with a durable butyl rubber surround, providing extended bass output and long-term reliability.

The robust construction includes a UV- and weather-resistant UL 94-V0 rated ABS baffle, a plated steel fire can enclosure, and a powder-coated aluminum mesh grille with dust protection. For safety, the CVS 801S LZ is certified to UL 1480 for fire-protected signaling systems and UL 2043 for air-handling spaces.

About the Tannoy CVS 801S LZ 8" In-Ceiling Subwoofer Loudspeaker for Installation Applications - Low Impedance Operation Only

The Tannoy CVS 801S LZ is a specialized in-ceiling subwoofer engineered to deliver dedicated low-frequency effects in custom installation projects where space and aesthetics are critical constraints. Designed exclusively for low-impedance operation, this 8-inch subwoofer is built around a high-excursion driver with a robust motor assembly, capable of moving significant air to reproduce deep bass frequencies typically associated with larger, floor-standing enclosures. Its round, low-profile chassis is constructed for seamless integration into standard ceiling cavities, allowing it to be concealed entirely behind a paintable grille. This design makes it an ideal solution for home theaters, high-end media rooms, and commercial spaces where the immersive impact of a subwoofer is desired without any visual footprint or floor space consumption, enabling a clean, uncluttered room design.

Acoustically, the speaker is designed to perform as part of a larger multi-channel or distributed audio system, providing the essential low-end foundation that smaller full-range in-ceiling speakers cannot reproduce. The driver is housed in a sealed, infinite baffle-style back-can that utilizes the ceiling cavity itself as part of its enclosure, optimizing its performance for extended, articulate bass response. This configuration allows it to handle significant power from an external amplifier, delivering tight, controlled bass that enhances movie soundtracks, music, and gaming experiences without the muddy resonance that can plague poorly integrated subwoofers. Its focused output ensures that low-frequency energy is effectively coupled into the room, contributing to a truly enveloping auditory experience.

Installation is streamlined for professional custom integrators. The chassis features a secure dog-leg clamping mechanism that grips the ceiling drywall or plasterboard firmly from behind, ensuring a stable, rattle-free mount. The included magnetic grille can be finished to match the ceiling exactly, rendering the speaker virtually invisible when not active. As it requires connection to an external amplifier, it offers integrators flexibility in system design, allowing it to be powered by dedicated subwoofer amplifiers or multi-channel AV receivers. The CVS 801S LZ represents a sophisticated tool for achieving full-range, high-fidelity audio in luxury installations where both performance and discretion are non-negotiable.
