The Martin Audio CDD15 is a high-output passive installation loudspeaker designed for demanding commercial and professional audio systems where strong projection, premium sound quality and controlled audience coverage are required. As the largest full-range loudspeaker in the Martin Audio CDD Series, the CDD15 is built for venues that need greater power, extended low frequency response and higher SPL capability from a single installed cabinet.

Available in black or white, the CDD15 can be specified for a wide range of venue styles, from darker entertainment spaces and performance-led environments through to lighter architectural interiors. Its clean cabinet design and screw-free perforated steel grille give it a refined installed appearance, making it suitable for commercial spaces where performance and presentation both matter.

The CDD15 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 provides powerful full-range output, clear vocal intelligibility and detailed music reproduction from a single cabinet. With 400W AES power handling and 1600W peak capability, the CDD15 is well suited to larger foreground music systems, performance spaces and high-output commercial installations.

Martin Audio’s Coaxial Differential Dispersion technology is designed to deliver more consistent coverage than conventional fixed-pattern loudspeakers. The CDD15 provides wider horizontal coverage close to the loudspeaker while projecting more effectively towards the rear of the listening area. This helps reduce excessive level differences across the room, supporting a more even listening experience for customers, guests or audiences.

The user-rotatable coaxial driver allows the loudspeaker to be installed in either portrait or landscape orientation while keeping the required coverage pattern aligned to the space. With 100°–60° horizontal dispersion and 60° vertical coverage, the CDD15 gives installers flexibility when working with different mounting heights, room layouts, stage positions, audience areas and architectural restrictions.

With a frequency response of 55Hz–18kHz ±3dB and useful low frequency extension down to 45Hz at -10dB, the CDD15 delivers a full and powerful sound without relying on a compact cabinet format. For venues requiring extended sub-bass or higher-impact music playback, it can also be combined with suitable Martin Audio subwoofers as part of a wider installed system.

The 68 litre birch plywood enclosure provides a robust platform for professional fixed installation. The cabinet includes 10x M8 fly points and is compatible with suitable Martin Audio mounting accessories, including wall bracket, yoke and eyebolt options. This makes it practical for a range of installation approaches, including wall mounting, suspension and performance-area sound reinforcement when specified with correctly rated hardware.

The CDD15 operates as an 8Ω passive loudspeaker and should be paired with suitable amplification and system processing. For best results, it should be used with appropriate Martin Audio controller or amplifier presets to optimise performance and provide loudspeaker protection.

The Martin Audio CDD15 is a strong choice for venues requiring a high-output passive loudspeaker with excellent clarity, controlled dispersion and professional installation flexibility. It is particularly well suited to live music venues, bars, clubs, hotels, leisure spaces, houses of worship, event rooms, performance areas and larger commercial audio systems where sound quality and coverage consistency are both critical.
