The Martin Audio CDD15-WR is a high-output weatherised passive installation loudspeaker designed for demanding commercial audio projects where powerful sound, controlled coverage and improved environmental protection are required. As the weatherised version of the CDD15, it is suitable for installations that may be subject to changing outdoor conditions, provided the loudspeaker is sheltered from direct exposure to the elements.

Available in black or white, the CDD15-WR is suitable for a wide range of professional venues and architectural environments. It is a strong choice for covered outdoor hospitality areas, hotel terraces, external bar and restaurant zones, leisure venues, concourses, transport hubs, visitor attractions, covered event spaces and larger commercial audio systems where a premium loudspeaker solution is required.

The loudspeaker uses a 15" low frequency driver with a 3" voice coil and a coaxially mounted 1.4" exit high frequency compression driver with a 3" voice coil. This driver configuration delivers powerful full-range output, strong vocal clarity and detailed music reproduction from a single cabinet. With 400W AES power handling and 1600W peak capability, the CDD15-WR is well suited to higher-output applications where smaller installation loudspeakers may not provide enough projection, headroom or low frequency performance.

Martin Audio’s Coaxial Differential Dispersion technology is designed to provide more consistent audience coverage than conventional fixed-pattern loudspeakers. The CDD15-WR delivers wider horizontal coverage close to the cabinet while projecting more effectively further into the listening area. This helps create a more balanced sound field across the venue, reducing excessive level differences between listeners positioned near the speaker and those further away.

The user-rotatable coaxial driver allows the cabinet to be installed in either portrait or landscape orientation, while keeping the dispersion pattern aligned to the space. With 100°–60° horizontal coverage and 60° vertical coverage, the CDD15-WR gives installers flexibility when working with different mounting heights, outdoor structures, audience areas and architectural constraints.

The CDD15-WR operates as an 8Ω passive loudspeaker and should be used with suitable low impedance amplification and appropriate system processing. Its frequency response of 55Hz–18kHz ±3dB, with useful low frequency extension down to 45Hz at -10dB, gives it a powerful and full-bodied sound for music-led commercial systems. For applications requiring extended sub-bass, it can also be paired with suitable Martin Audio subwoofers as part of a larger system design.

The weatherised construction supports reliable performance in more challenging environments. The CDD15-WR is environmentally tested to IP54 and includes a water and particle resistant grille, zinc plated mild steel protective grille with powder coated finish, weatherised backing, weatherproof input panel cover and cable gland. These features help protect the connection area and speaker components when installed correctly in suitable outdoor or semi-exposed locations.

The 68 litre composite enclosure measures 429mm x 691mm x 413mm and weighs 28.3kg. It includes 10x M8 fly points, allowing professional suspension or mounting using compatible accessories and correctly rated hardware. The black and white finish options make it suitable for both darker entertainment-led spaces and lighter architectural environments.

The Martin Audio CDD15-WR is a premium choice for professional AV installations requiring a powerful weatherised passive loudspeaker with high SPL capability, controlled audience coverage and refined architectural styling. It is particularly suitable for projects where outdoor resilience, strong foreground music performance and long-term commercial reliability are key requirements.
