Martin Audio CDD5BTX-WR – IP54 Outdoor 5" 70V Coaxial Speaker Black

Product Overview

The Martin Audio CDD5BTX-WR is an IP54-rated outdoor coaxial loudspeaker engineered for commercial AV installations that demand reliable performance in changing environmental conditions. This weatherized commercial speaker integrates a 70V/100V line transformer, making it fully compatible with distributed audio amplifier systems across large-scale outdoor on-wall AV installation projects. Designed for sheltered outdoor deployment — from transport concourses and hotel exteriors to retail courtyards and house of worship exteriors — the CDD5BTX-WR delivers consistent, intelligible audio in a discreet, architecturally appropriate black enclosure. It is the weatherized outdoor variant of Martin Audio's proven indoor CDD5 series, carrying IP54 environmental certification for dust and water resistance.

Product Description

The Martin Audio CDD5BTX-WR employs Coaxial Differential Dispersion technology — a patent-pending driver architecture that places the high-frequency transducer at the acoustic centre of the low-frequency cone. This coaxial arrangement achieves point-source summation of LF and HF energy, delivering consistent frequency response across a wide horizontal coverage pattern of 120°–90° and 80° vertically. The user-rotatable driver allows the coverage pattern to be oriented to suit horizontal or vertical cabinet placement without any mechanical modification to the enclosure.

IP54 certification confirms dust-tight protection against particulate ingress and resistance to water splashing from any direction — appropriate for sheltered outdoor environments including covered terraces, transport canopies, and stadium concourses. The operating temperature range of -20°C to +70°C accommodates installations across a broad range of climates. The ABS moulded enclosure houses a 5.25" (130mm) LF driver with a 1.25" (32mm) voice coil and a 0.75" (19mm) HF fabric dome with neodymium motor, crossed over passively at 2.5kHz.

The integrated 70V/100V transformer supports tap settings of 3W, 6W, 12.5W, and 25W on 70V line, and 6W, 12.5W, and 25W on 100V line — giving the system designer precise SPL management across distributed zones. The dual cable gland and push-lock input panel facilitate daisy-chaining multiple cabinets without external breakout boxes, reducing installation complexity and cable runs. The CDD5BTX-WR ships with a dedicated pan-and-tilt weatherised mounting bracket accommodating both wall and ceiling orientation. A screw-free, zinc-plated powder-coated grille with weatherised backing completes the IP54-compliant enclosure. Available as a colour-matched pair with the CDD5WTX-WR white variant.

Technical Specifications

Frequently Asked Questions

What does IP54 mean on the CDD5BTX-WR?

IP54 is an ingress protection rating per IEC 60529. The first digit (5) confirms the enclosure is dust-tight — no harmful dust ingress. The second digit (4) confirms protection against water splashing from any direction. It does not mean the cabinet is submersible or suitable for direct rain exposure without shelter.

What mounting options are available?

The CDD5BTX-WR ships with a pan-and-tilt weatherised bracket for wall or ceiling mounting. The enclosure also features 6 × M5 threaded inserts compatible with third-party wall and ceiling brackets, supporting both vertical and horizontal cabinet orientations.

What amplifier is required for 70V operation?

Any 70V constant-voltage amplifier is compatible. Select the appropriate transformer tap (3W, 6W, 12.5W, or 25W) to match the target SPL per zone. Multiple CDD5BTX-WR cabinets can be daisy-chained across a single amplifier channel using the built-in dual cable gland without exceeding the amplifier's rated wattage.

Can this speaker be used on a standard 8Ω amplifier?

The CDD5BTX-WR is a 70V/100V transformer-equipped model. For direct 8Ω amplifier operation without a transformer, refer to the non-TX weatherized variants in the CDD-WR range. The transformer bypasses the 8Ω output on TX models.

How does the CDD5BTX-WR differ from the indoor CDD5?

The WR (Weatherized) suffix designates IP54-certified environmental protection, a weatherised grille backing, weatherproof input panel cover, and a weather-resistant mounting bracket. The indoor CDD5 lacks these protections and is not suitable for outdoor or high-humidity installations.

Can multiple CDD5BTX-WR speakers be daisy-chained?

Yes. The dual cable gland input panel allows the 70V/100V line signal to pass directly through to the next cabinet without external junction boxes. The number of cabinets per channel is limited by the total wattage of all taps versus the amplifier's output rating.

Is a white version available?

Yes. The CDD5WTX-WR is the white-finish equivalent, identical in all technical specifications. Custom RAL colour finishes are also available as a factory cost option.

What is the warranty on Martin Audio CDD-WR products?

Martin Audio products are covered by a standard manufacturer warranty. Please contact Creation Networks at creationnetworks.net for warranty registration details and terms applicable to your region.
