The new Martin Audio XD range, actually XD12 and XD15, was designed to provide high acoustic pressure and extended bandwidth. Its asymmetric enclosure design and user rotatable constant directivity high frequency horn, covers many different applications: Sound reinforcement, distributed sound system, dance floor as well as stage monitoring.
One of the development priorities has been to redesign the transducers in order to get high efficiency and high SPL level within a small volume. As an example, the 15” long excursion woofer (with its 4” voice coil) of the XD15 shows a 100 dB/1 W /1 m sensitivity, capable of 133 dB SPL (1m) peak level and 127 dB in continuous mode. To achieve this, new neodymium motors have been design with advanced cooling to reduce power compression to negligible levels, as well as a new cone material, epoxy coated cellulose pulp to increase mass-rigidity ratio. The XD12 uses a 1,7” polyimide dome compression driver with a 1” throat where the XD15 is fitted with a 3” titanium diaphragm and a 1,4” throat. This explains the high frequency response difference (18 kHz instead of 20 kHz at -3dB) and the difference between the two crossover points 1,75 kHz in one case and 2 kHz in the other one. Both drivers are loaded with a 90° user rotatable 80°H x 50°V constant directivity horn easily adapting to vertical or horizontal usage.
XD12 without grille.
XD enclosures are made of touring grade plywood, coated with high durability polyurethane, while the transducers are protected with a stamped steel grille. M8 inserts are available on the box to match different type of accessories (brackets …) and a 35 mm true pole mount feature.
Both models can be used in passive or bi-amp mode. When used in bi-amp configuration, it is strongly recommended to use Martin Audio DX1.5 or DX2 controllers as well as adding WS18X or 218X subwoofer.

Launched at the PLASA show, at the same time as the Midas PRO1 console, the DN9610 is an AES repeater for extending AES50 multichannel digital audio network connections (Cat-5e/Cat-6 cabling) up to 100m. Each AES50 feed can carry 24 bidirectional channels at 96 kHz or 48 bidirectional channels at 48 kHz. With two independent AES50 ports, the DN9610 is capable of extending two AES50 streams by up to 100m and multiple DS9610s can be daisy chained in series for considerable runs.
