Martin Audio CDD15B-WR – IP54 Outdoor 15" Very High-Output Coaxial Speaker Black

Product Overview

The Martin Audio CDD15B-WR is an IP54-rated outdoor coaxial loudspeaker in black finish, representing the highest-output model in the weatherized CDD-WR series. Engineered for commercial AV installations demanding the ultimate in single-enclosure sonic performance from an outdoor on-wall AV installation, the CDD15B-WR delivers 126dB continuous maximum SPL at 1m from a 15" (380mm) Coaxial Differential Dispersion driver. This weatherized commercial speaker is suited to primary reinforcement in outdoor entertainment venues, large transport hubs, open-air theatre, and stadium exterior positions where high SPL, wide horizontal coverage, and consistent off-axis frequency response are all required. Operating at 8Ω for direct power amplifier connection, it supports flyable suspension via ten M8 fly points. The black-finish complement is the CDD15W-WR.

Product Description

Martin Audio's Coaxial Differential Dispersion technology in the CDD15B-WR delivers more consistent audience coverage than systems with fixed horizontal × vertical coverage patterns. The CDD driver projects relatively more output toward the rear of the audience while maintaining wide horizontal coverage close-up — a characteristic particularly valuable in outdoor fan-shaped or wide audience geometries. The innovative CDD driver achieves point-source summation of the LF and HF sections, eliminating off-axis frequency response variations associated with non-coaxial designs. A static waveguide integrated with the unique cone shape maintains consistent dispersion through the high-frequency range, avoiding the HF beaming that affects conventional coaxial designs.

The 15" (380mm) LF driver features a 3" (75mm) voice coil in a long-excursion, shared ferrite motor system alongside the 1.4" (36mm) exit / 3" (75mm) voice coil titanium dome compression driver, crossed over passively at 1.6kHz. The frequency response extends from 55Hz to 18kHz (±3dB), suitable for full-range music programme reproduction in outdoor entertainment environments. The 100dB sensitivity and 400W AES / 1600W peak power handling combine to deliver 126dB continuous maximum SPL at 1m, providing meaningful headroom for outdoor venues with high ambient noise levels.

IP54 environmental certification — dust-tight and resistant to water splashing from any direction — qualifies the CDD15B-WR for sheltered outdoor deployment including covered outdoor venues, stadium exterior positions, hotel exterior event spaces, and large transport hubs. The operating temperature range of −20°C to +70°C covers a broad climate range without derating. The 68-litre UPM Formi composite enclosure, screw-free zinc-plated weatherised grille, and 20A push-lock weatherproof connectors complete the outdoor installation package. Ten M8 fly points allow suspended installation from trusses and structural rigging. Browse the full Martin Audio range at Creation Networks.

Technical Specifications

Frequently Asked Questions

What does IP54 mean for the CDD15B-WR?

IP54 per IEC 60529 indicates dust-tight protection (digit 5) and resistance to water splashing from any direction (digit 4). Sheltered outdoor installation is required; the cabinet is not rated for direct rain exposure or submersion.

What mounting options are available?

Ten M8 fly points provide full suspension rigging capability from trusses and structural rigging points. The user-rotatable coaxial driver allows horizontal or vertical coverage orientation to match installation geometry. Note: no wall bracket inserts are listed for the CDD15B-WR — consult Creation Networks for bracket options for this model.

What amplifier is required?

The CDD15B-WR is an 8Ω passive loudspeaker. Any standard stereo or multi-channel power amplifier rated for 8Ω loads is compatible. With 100dB sensitivity and 400W AES handling, the CDD15B-WR achieves 126dB continuous SPL at 1m.

How does the CDD15B-WR differ from the indoor CDD15?

The WR suffix indicates IP54 environmental certification, a weatherised grille backing, weatherproof input connectors, and weather-resistant mounting hardware not present on the indoor CDD15.

What makes the CDD15B-WR’s coverage pattern suitable for outdoor use?

The Coaxial Differential Dispersion driver projects relatively more output toward the rear of the audience than a conventional constant-directivity horn, while maintaining wide horizontal coverage close-up. This characteristic is well-suited to fan-shaped outdoor audiences and wide coverage geometries common in outdoor commercial AV applications.

Is a 70V/100V version of the CDD15B-WR available?

There is no TX (transformer-equipped) variant of the CDD15-WR. For 70V/100V distributed audio at this output level, consult a Creation Networks AV specialist for system design guidance.

Is a white version available?

Yes. The CDD15W-WR is the white-finish equivalent with identical technical specifications.

What warranty applies?

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