Martin Audio CDD12-WR 12" Weather-Resistant Coaxial On-Wall Loudspeaker
The CDD12-WR is the medium-throw weather-resistant CDD, a 12" long-excursion LF driver with an aluminium demodulating ring sharing a motor with a coaxial 1" exit polyimide compression driver in a 38 litre composite enclosure. It puts out 128dB peak and covers 110 degrees close in, tightening to 60 degrees down the throw, which is the behaviour you want across an outdoor stadium seating block or a large concourse.
Martin Audio rates it for operating temperatures from -20C to +70C and tests it to IP54, for outdoor use sheltered from direct exposure. The screw-free grille is zinc-plated mild steel with a powder coat and a water and particle resistant backing, and every fixing on the cabinet is stainless steel. Removing the grille lets you rotate the coaxial driver for portrait or landscape mounting, and integral inserts take eyebolts, a weatherised wall bracket or a horizontal yoke. Standard finishes are RAL9005 black and RAL9016 white, with any RAL to order.
