Bose EdgeMax EM90 – In-Ceiling Premium Loudspeaker (White)

Product Overview

The Bose EdgeMax EM90 is a commercial-grade in-ceiling loudspeaker engineered for edge-of-ceiling installation, allowing placement at the perimeter of a room rather than the center. This design makes it particularly effective in conference rooms, boardrooms, and commercial meeting spaces where HVAC ducts, structural elements, or aesthetic requirements prevent traditional center-ceiling speaker placement. The EM90 delivers wide horizontal coverage from its edge position, providing consistent SPL across the listening area. Available from Creation Networks, the EM90 is a premium solution for integrators specifying distributed audio in architecturally constrained spaces.

Product Description

← →

The EdgeMax EM90 uses a 90-degree dispersion pattern oriented horizontally from the ceiling edge, directing sound toward the center of the room where listeners are seated. Its coaxial driver configuration combines a low-frequency woofer with a high-frequency tweeter on the same axis, delivering coherent, time-aligned audio across the frequency range. The enclosure is designed for flush installation with a low-profile grille that sits close to the ceiling surface, maintaining a clean architectural appearance.

The EM90 features a transformer for 70V/100V distributed audio systems as well as a low-impedance direct connection option, giving installers flexibility to integrate with a wide range of commercial amplifiers and DSP platforms including the Bose ControlSpace series. The back-can is provided to allow installation in plenum-rated ceiling spaces where an enclosure is required by building code, supporting compliance in commercial construction projects.

Coverage from an edge position is a distinct advantage in rooms with obstructed ceilings or where even sound distribution from a single speaker location is required. The EM90 is frequently deployed in pairs or arrays along two parallel edges of a room to achieve even coverage without the symmetry constraints of traditional grid-ceiling layouts. Its white finish blends with standard commercial ceiling tile and drywall installations.

Key Features

• Edge-of-Ceiling Design — Installs at the room perimeter, directing audio toward occupied seating areas from a side-firing position.
• 90-Degree Horizontal Dispersion — Wide pattern ensures consistent SPL coverage across the listening plane without multiple speaker positions.
• Coaxial Driver Configuration — Time-aligned LF and HF drivers on the same axis deliver coherent, natural-sounding audio reproduction.
• 70V/100V Transformer Included — Supports distributed audio system integration with standard commercial amplifiers.
• Low-Impedance Direct Drive Option — Provides installation flexibility for both distributed and direct-drive amplifier configurations.
• Plenum Back-Can Compatible — Suitable for plenum-rated ceiling installations as required by commercial building codes.
• Low-Profile Flush Grille — White finish grille sits close to the ceiling surface for a clean, minimal visual footprint.
• Commercial-Grade Construction — Built for continuous operation in commercial environments with stable, consistent acoustic performance.

Typical Applications

• Boardroom distributed audio
• Conference room ceiling audio
• Commercial meeting space sound systems
• Government space audio installations

Frequently Asked Questions

What makes edge-of-ceiling installation different from standard in-ceiling placement?

Standard in-ceiling speakers fire straight down from the center of a room. The EdgeMax EM90 is designed to mount at the ceiling perimeter and project sound horizontally across the room. This is useful when the center ceiling is obstructed by HVAC, lighting, or structural elements, or when a single speaker position needs to cover a larger area.

Can the EM90 be used in a 70V distributed audio system?

Yes. The EM90 includes an internal transformer with taps for 70V and 100V distributed systems. It can also be wired as a direct 8-ohm load for low-impedance amplifier connections.

Is a back-can required for installation?

A back-can is required when installing in plenum-rated ceiling spaces as required by most commercial building codes. The Bose back-can accessory is sold separately and designed specifically for the EM90 enclosure.

What amplifier or DSP is recommended for use with the EM90?

The EM90 is compatible with the Bose ControlSpace series DSPs and PowerMatch amplifiers. It also integrates with third-party commercial amplifiers. Contact Creation Networks for system design assistance.

How many EM90s are typically needed to cover a conference room?

Coverage depends on room size and ceiling height. In a standard conference room (approx. 5 x 8 m), two EM90s installed on opposing edges typically provide even coverage. A Bose system design or acoustic simulation is recommended for larger or irregular spaces.

What warranty does the EM90 carry?

The Bose EdgeMax EM90 is covered by Bose Professional's limited warranty. Contact Creation Networks for warranty registration and support.
