LD Systems MAILA SUB – 2 x 15″ Powered Bandpass PA Subwoofer

LD Systems MAILA SUB – 2 x 15 inch Powered Bandpass PA Subwoofer
MAILA SUB forms the basis of every MAILA system. The 2.5 kW 2×15” high-performance subwoofer features a bandpass design and, with its newly developed SysCore® DSP, delivers a massive and powerful bass foundation in any application.
The acoustic concept of the MAILA SUB is based on a planar wave bandpass design with quarter-wave horn and symmetrical driver construction. By placing the two 15” speakers opposite each other, the MAILA SUB enables exceptional impulse compensation, resulting in a powerful and precise low-frequency punch.
The four large-area bass reflex openings, in conjunction with the enclosure design, ensure optimised airflow and reduced flow losses, resulting not only in a lower noise level, but above all in higher efficiency at low frequencies.
The enclosure of the subwoofer is made of 18 mm thick birch plywood. The MAILA SUB defies the rigours of everyday road use with a hard-wearing polyurea paint finish. A total of six carrying handles ensure optimum grip during assembly and dismantling. For comfortable transport on longer trips, the optional MAILA SUB CB castor board is the optimal choice.
With LogoLink®, LD Systems has added another innovation to MAILA. Via the free MAILA app (iPadOS), every MAILA system can be quickly, easily and precisely adjusted and wirelessly supplied with software updates. Once connected, the app automatically recognises the existing MAILA components and enables the system to be set up quickly and easily – including calculation of the SAT angles – in the run-up to an event. The highlight: the wireless antennas are invisibly integrated into the LD logo of the MAILA SUB.
