Martin Audio CDD5B – 5" Passive Coaxial On-Wall Speaker, Pair (Black)

Product Overview

The Martin Audio CDD5B is an ultra-compact passive two-way micro loudspeaker, sold as a matched pair, designed for discreet architectural sound reinforcement in commercial interiors. Built around a patent-protected 5" (125mm) LF / 0.7" (19mm) HF Coaxial Differential Dispersion driver in a rigid ABS moulded enclosure, the CDD5B delivers consistent full-range coverage in applications where speaker visibility must be minimized — including bars, museum galleries, hotel foyers, convention centre concourses, retail environments, and houses of worship. The enclosure supports both horizontal and vertical orientations and ships with a dedicated omni-directional mounting bracket. The complete Martin Audio CDD series is available at Creation Networks.

Product Description

The Martin Audio CDD5B's Coaxial Differential Dispersion technology addresses a fundamental limitation of fixed-pattern two-way loudspeakers: uneven coverage from front to rear of the listening area. By projecting proportionally more output toward the rear of the audience zone and maintaining wide horizontal coverage close-up, the CDD5B distributes sound more evenly across depth without requiring additional delay fills in many standard room configurations. Its CDD driver achieves point-source summation of the LF and HF sections, eliminating the off-axis frequency response variation in the crossover region that is characteristic of spatially separated driver designs. The curved ABS enclosure allows surface mounting close to a wall or ceiling using the included omni-directional bracket, which accommodates a range of installation angles without requiring custom hardware. An optional close-mount ceiling bracket is also available for flush-proximity ceiling applications. The CDD5B can be supplied in any RAL colour to order beyond the standard black (RAL9005) and white (RAL9016) options, supporting branded or themed architectural installations. The speaker should be used with a compatible system controller — such as the Martin Audio DX4.0 — or a limiter-equipped amplifier to provide system protection. When driven via a Martin Audio iKON amplifier, DSP and FIR-based presets deliver optimized frequency response and limiter operation. A 70V/100V transformer option is available as the CDD5TX-WR for distributed system installations. For matched coverage at larger scales, the CDD5B can be integrated into systems alongside larger CDD models. Browse all CDD micro and compact speakers at creationnetworks.net.

Frequently Asked Questions

Is the CDD5B sold individually or as a pair?

The CDD5B is sold as a matched pair. Each order includes two CDD5B loudspeakers along with their omni-directional mounting brackets.

What amplifier is recommended with the CDD5B?

Martin Audio recommends using the CDD5B with a compatible controller equipped with appropriate limiter settings to protect the speaker. The Martin Audio DX4.0 system controller paired with an iKON amplifier provides DSP and FIR-based presets for optimized performance and limiter operation.

Can the CDD5B be used in a 70V/100V distributed system?

Not in its standard form. For constant-voltage distributed systems, Martin Audio offers the CDD5TX-WR, which integrates a 70V/100V line transformer. Contact Creation Networks to enquire about CDD5TX-WR availability.

How does the Differential Dispersion pattern improve intelligibility in a room?

The CDD5B distributes proportionally more output toward the rear of the listening area to compensate for distance attenuation, while maintaining wide horizontal coverage close to the speaker. This produces more even SPL distribution front-to-back than speakers with fixed symmetric dispersion patterns, reducing the need for supplementary delay fills in many room configurations.

What surface finishes are available beyond black and white?

The CDD5B can be ordered in any RAL colour from the factory to match specific architectural, branding, or interior design requirements. Standard stock is black (RAL9005); white (RAL9016) is available as the CDD5W. Contact Creation Networks for custom colour lead times and pricing.

Can the CDD5B be ceiling-mounted?

Yes. In addition to the included omni-directional bracket, Martin Audio offers an optional close-mount ceiling bracket designed for flush-proximity ceiling installation. Contact Creation Networks for compatible accessory part numbers.

What warranty applies to the CDD5B?

Martin Audio products carry a standard manufacturer warranty. Contact Creation Networks at creationnetworks.net for warranty terms, registration, and dealer support.
