The Martin Audio CDD10TX is a compact 10” passive installation loudspeaker with an integrated 70V/100V line transformer, designed for commercial audio systems where strong output, controlled coverage and efficient distributed speaker operation are required. Available in black or white, it is suitable for a wide range of professional environments where high-quality music and speech reinforcement need to be delivered from a refined architectural cabinet.

As the transformer-equipped version of the CDD10, the CDD10TX is built for high impedance loudspeaker systems. It is particularly useful in projects where multiple speakers are required across larger rooms, multiple areas or long cable runs. The integrated 70V/100V transformer allows the speaker to be daisy-chained as part of a distributed system, with selectable tap settings to help manage amplifier loading, output levels and system zoning.

The CDD10TX uses a 10” low frequency driver with a 2.5” voice coil and a 1” exit high frequency compression driver with a 1.4” voice coil. This coaxial configuration provides clear and coherent sound from a compact enclosure, supporting both foreground music and speech applications. With a frequency response of 65Hz–20kHz ±3dB, the CDD10TX offers a full-range tonal balance that makes it well suited to hospitality, retail, education, leisure, museum, gallery, corporate and house of worship installations.

Martin Audio’s Coaxial Differential Dispersion technology is central to the speaker’s performance. The coverage pattern is designed to provide wider horizontal dispersion close to the loudspeaker while projecting more effectively towards the rear of the listening area. This helps create a more even sound field across the room, reducing excessive level differences between listeners positioned close to the speaker and those further away.

The user-rotatable coaxial drive unit provides flexibility for both portrait and landscape installations. With 110°–75° horizontal coverage and 60° vertical coverage, the CDD10TX can be adapted to suit different room layouts, mounting heights and audience areas. This makes it practical for venues with architectural restrictions, varied seating plans, high ceilings or limited mounting positions.

With 120W AES power handling and 240W peak capability, the CDD10TX provides dependable performance for commercial systems where high impedance operation is required. It is important to note that this model is transformer operation only and does not include a low impedance mode. The 100V tap settings are 120W, 60W and 30W, while the 70V tap settings are 120W, 60W, 30W and 15W.

The 28 litre composite enclosure is finished in black or white textured paint and fitted with a screw-free perforated steel grille with scrim cloth backing. The cabinet measures 323mm x 513mm x 310mm and weighs 16.9kg, giving it the output and cabinet volume required for more demanding commercial applications while remaining compact enough for architectural installation.

The CDD10TX includes 6x M8 inserts for wall bracket mounting and 10x M8 fly points, allowing a range of professional mounting approaches using suitable Martin Audio accessories and correctly rated fixings. It should be used with appropriate system processing and compatible limiter settings to support long-term loudspeaker protection and performance.

The Martin Audio CDD10TX is a strong choice for commercial AV projects requiring a 100V installation loudspeaker with premium sound quality, controlled coverage and efficient distributed system design. It is particularly suitable for projects where the system needs higher output than smaller transformer-equipped speakers while retaining a clean, professional installed appearance.
