Sonance Invisible Series 6.5-Inch Commercial In-Wall/In-Ceiling Loudspeaker in White - 40198

Sonance 40198 Invisible Series 6.5-Inch Commercial In-Wall/In-Ceiling Loudspeaker in White

The Sonance 40198 Invisible Series commercial in-wall/in-ceiling speaker combines concealed finish-over installation, Motion Flex driver technology and compatibility with 4-ohm, 70V and 100V audio systems. Rated for 100 watts RMS, it offers 170-degree hemispherical dispersion up to 10kHz to support coverage planning in hospitality and other guest-facing interiors. Wave Flex handles high-frequency reproduction and Air Flex produces bass, while installation beneath compatible wall or ceiling finishes leaves no exposed grilles or hardware. This is architectural audio that keeps the space, rather than the equipment, in focus.

Key Features

Truly Invisible Installation

Preserve the finished wall or ceiling instead of interrupting it with a speaker grille. Concealed construction supports surface treatments including drywall, select plasters, wallpaper, leather and wood veneer. Covering materials must be flexible and lightweight, with a maximum total finish thickness of 1/8 in (3 mm); 1-1.5 mm is optimal. That finish-over approach lets luxury commercial interiors retain their visual focus while integrating sound beneath the surface.

4-Ohm, 70V and 100V System Flexibility

The Sonance Laminated Core Transformer accommodates distributed-audio installations, with 4-ohm bypass for compatible low-impedance systems. Choose 30W, 15W or 7.5W taps for either 70V or 100V operation; a 3.8W tap is also available at 70V. For amplification planning, distinguish those transformer settings from the speaker's 100 watts RMS power-handling rating. Sensitivity is 84dB at 2.83V/1m, providing another defined reference for system design.

170-Degree Hemispherical Coverage Up to 10kHz

Broad sound distribution helps installers plan listening areas without treating every speaker as a narrowly focused source. Hemispherical dispersion spans 170 degrees up to 10kHz, and the broad-coverage design can allow fewer speakers. For hospitality and other guest-facing interiors, that distribution is useful when planning speaker locations across the space.

Motion Flex: Wave Flex and Air Flex

Separate mechanisms address different parts of the sound spectrum. Wave Flex uses bending-wave reproduction for high-frequency detail, while Air Flex pairs an air-pulse diaphragm with a 6.5 in carbon fiber woofer for bass. An acoustically isolated baffle brings these complementary technologies together behind the finished surface, supporting detailed reproduction without putting the drivers on display.

CDX Crossover and Frequency Response

From lower-level listening to higher playback levels, the CDX crossover is designed for warmth and clarity. It complements the separate high- and low-frequency driver technologies rather than making visual hardware part of the listening space. Published frequency response is 50Hz-30kHz (+/-3dB).¹

D.I.S.C. Finish Calibration

Finish thickness is part of the acoustic installation, not just a cosmetic choice. D.I.S.C. calibration measures the topping layer to help keep finishing and performance consistent across installations. For projects with multiple concealed speakers, it provides a way to check the material covering each speaker rather than judging the surface by appearance alone.

Plan for the Mounting Cavity and Wiring

A listed mounting depth of 3.39 in gives integrators a specific cavity requirement for wall or ceiling planning. Screw terminals with strain relief provide the wired connection. For projects requiring certification review, the documented standards are UL 2043 and UL 1480.

Footnotes:

¹ The product specifications and data sheet state 50Hz-30kHz; the installation manual states a frequency range of 50Hz-20kHz.

Measured performance figures reflect manufacturer testing under specific conditions and may vary with the installation, settings and use.

For wall installations, speakers should be at least 7 ft (2.13 m) above the floor.

The operating temperature range is -4 degrees F to 122 degrees F (-20 degrees C to 50 degrees C).
