Bose DesignMax DM8C – Commercial In-Ceiling Loudspeaker Pair

Product Overview

The Bose DesignMax DM8C is a commercial-grade in-ceiling loudspeaker engineered for distributed audio systems in demanding commercial environments. Sold as a pair, the DM8C delivers consistent, wide-coverage sound reproduction suited to corporate offices, conference rooms, and multi-purpose spaces. Designed to integrate directly with Bose ControlSpace and third-party DSP ecosystems, these in-ceiling speakers support both 70 V/100 V distributed audio configurations and low-impedance direct drive. The DM8C belongs to the DesignMax series — Bose's purpose-built commercial loudspeaker line for installed sound applications requiring reliable, scalable audio distribution.

Product Description

The Bose DesignMax DM8C features an 8-inch woofer paired with a 1-inch tweeter in a two-way coaxial configuration, producing smooth frequency response across the entire speech and music range. The coaxial driver arrangement ensures coincident point-source imaging, which is particularly valuable in reverberant commercial spaces such as lobbies, open-plan offices, and training rooms where listener positioning varies widely.

With a 100-degree conical coverage pattern, the DM8C provides uniform sound distribution over a wide listening area, reducing the number of speakers required per zone and simplifying the overall system design. The included Cleveland rotating dog-ear mounting system allows for tool-free, back-can-compatible installation without requiring additional hardware. A paintable white grille is included, allowing the speaker to blend with standard suspended or drywall ceiling finishes.

The DM8C supports selectable transformer taps for 70 V and 100 V distributed audio systems, making it fully compatible with commercial amplification infrastructure. It is also rated for direct 8-ohm operation when zone controllers or low-impedance amplifiers are used. This pair listing (SKU 802080-0210) provides two DM8C speakers — the standard installation quantity for a single stereo zone or dual-mono distributed audio zone.

Technical Specifications

Frequently Asked Questions

Are these speakers compatible with Bose ControlSpace DSP systems?

Yes. The DM8C is designed to integrate with Bose ControlSpace ESP and EX series processors. Bose ControlSpace Designer software includes DM8C presets for streamlined commissioning.

Can the DM8C be used with third-party amplifiers and DSPs?

Yes. The DM8C operates at standard 8-ohm impedance and supports 70 V / 100 V distributed audio, making it compatible with virtually any commercial amplification platform including Crown, QSC, and Extron.

Does the DM8C require a back can?

A back can is not required but is recommended in plenum or fire-rated ceiling assemblies to meet local building codes. Bose offers compatible back cans for the DesignMax series.

What is the recommended ceiling height for the DM8C?

With its 100-degree coverage pattern, the DM8C is well-suited for ceiling heights of 8 to 12 feet. At 10 feet, a single speaker provides approximately 18 feet of coverage diameter at the –6 dB points.

This listing is sold as a pair — does that mean two speakers are included?

Yes. Each order includes two DM8C loudspeakers, suitable for a single stereo zone or two independent mono zones in a distributed audio system.

What transformer tap settings are available?

The built-in 70 V / 100 V transformer offers selectable taps at 7.5 W, 15 W, 30 W, and 60 W, accommodating a wide range of zone power budgets in commercial distributed audio systems.

What warranty coverage does the DM8C carry?

Bose Professional provides a 5-year limited warranty on DesignMax series loudspeakers. Creation Networks supports warranty claims and provides commercial AV integration support — contact us at creationnetworks.net.
