Martin Audio CDD8WTX-WR – IP54 Outdoor 8" 70V Coaxial Speaker White

Product Overview

The Martin Audio CDD8WTX-WR is an IP54-rated outdoor coaxial loudspeaker in white finish, incorporating a 70V/100V line transformer for deployment in large-scale distributed commercial AV systems. This weatherized commercial speaker features an 8" (200mm) Coaxial Differential Dispersion driver, delivering meaningfully higher output than 5" or 6" TX models while remaining compact enough for sheltered outdoor on-wall AV installation across transport hubs, hotel exterior areas, outdoor entertainment venues, and stadium concourses. The 70V/100V transformer enables multiple CDD8WTX-WR cabinets to be daisy-chained from a single amplifier channel, improving amplifier efficiency and reducing cable infrastructure costs. It is the white-finish complement to the CDD8BTX-WR; the 8Ω variant is the CDD8W-WR.

Product Description

Martin Audio's Coaxial Differential Dispersion technology positions the 1" (25mm) exit HF driver at the acoustic centre of the 8" (200mm) LF cone, achieving point-source summation of both frequency bands. This architecture delivers consistent off-axis frequency response and controlled coverage across the horizontal and vertical dispersion pattern. The user-rotatable coaxial drive unit allows the coverage ellipse to be re-oriented for horizontal or vertical cabinet placement without any enclosure modification, providing the installation designer with full flexibility in coverage aiming.

IP54 environmental certification — dust-tight protection and resistance to water splashing from any direction — qualifies the CDD8WTX-WR for sheltered outdoor environments including covered terraces, transport canopies, exterior hotel areas, and outdoor stadia concourse positions. The operating temperature range of −20°C to +70°C accommodates installations across a wide range of climate conditions. The UPM Formi composite enclosure provides the acoustic and mechanical durability required for outdoor deployment subject to thermal cycling and humidity variation.

The integrated 70V/100V transformer connects via a 5-way weatherproof connector, and the built-in dual cable gland allows multiple CDD8WTX-WR cabinets to be daisy-chained directly on the 70V/100V line without external breakout hardware, improving amplifier efficiency across large distributed zones. The screw-free zinc-plated weatherised grille with powder-coated and weatherised backing maintains the IP54 rating while allowing tool-free removal for servicing.

Frequently Asked Questions

What does IP54 mean for the CDD8WTX-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?

The CDD8WTX-WR features threaded inserts for standard commercial wall and ceiling bracket systems. The user-rotatable coaxial driver allows horizontal or vertical coverage orientation to match cabinet placement.

What amplifier is required for 70V/100V operation?

A constant-voltage 70V or 100V distributed audio amplifier is required. Select the appropriate transformer tap to match the target SPL per zone. Multiple CDD8WTX-WR cabinets can be daisy-chained via the dual cable gland inputs on a single amplifier channel.

What is the 5-way connector used for?

The 5-way weatherproof connector carries the 70V/100V line signal to the integrated transformer, enabling connection to the distributed audio amplifier. The dual cable glands allow the line to pass through to the next cabinet in the daisy chain.

How does the CDD8WTX-WR differ from the indoor CDD8?

The WR suffix indicates IP54 environmental certification, weatherised grille backing, weatherproof connectors, and weather-resistant mounting hardware not present on the indoor CDD8.

Can multiple CDD8WTX-WR cabinets be daisy-chained?

Yes. The built-in dual cable gland passes the 70V/100V line signal directly to the next cabinet without external junction boxes. Ensure total tap wattage of all chained cabinets does not exceed the amplifier’s rated output.

Is a black version available?

Yes. The CDD8BTX-WR is the black-finish equivalent with identical technical specifications.

Is an 8Ω non-transformer version available?

Yes. The CDD8W-WR (white) and CDD8B-WR (black) are 8Ω passive variants without the 70V/100V transformer for direct amplifier connection.
