DDX12/H
Compact Full Range System

Features

• Fixed installations in Government, Education, Museums, Hotels and hospitality

DDX12 is part of the DDX series. Combining the ‘point-source’ benefits of coaxial designs with the consistent coverage of differential dispersion technology, DDX full-range systems project sound evenly front-to-back while exhibiting wide horizontal coverage close to the speaker — delivering ultimate fidelity and impact to all corners of the audience.

The DDX12 is a high-performance system designed for professional applications that require high output levels from a very compact enclosure. Its high-specification 12” (300mm) LF /1” exit HF coaxial differential dispersion driver delivers perfect sound across the audience over medium throw distances. The LF driver has a 2.5” (65mm) voice coil and efficient motor with an aluminium demodulating ring to minimise distortion, while the HF driver utilises a 1.75”(44mm) polyimide diaphragm and features a low-compression phase plug to reduce non-linearity. The coaxial differential dispersion driver can be easily rotated for horizontal or vertical orientation depending on venue design requirements.

The DDX12 is constructed from durable plywood, finished with hard wearing black textured coating paint, and fitted with a screw-free steel grille, M8 inserts for a wall bracket and eyebolt suspension, plus a pole mount socket.

Ergonomic handles at the rear of the enclosure make for easy
handling while maintaining clean lines.
