PROPERTIES
MAILA SUB forms the basis of every MAILA system. The 2.5 kW 2×15” high-
performance subwoofer works in bandpass design and, with its newly developed
SysCore® DSP, delivers a massive and powerful bass foundation in every
application.
The acoustic concept of the MAILA SUB is based on a planar wave bandpass
design with a quarter wave horn and a symmetrical driver structure. By
arranging the two 15” speakers opposite each other, the MAILA SUB enables
exceptional impulse compensation, which results in powerful and precise low-
frequency pressure.
The four large-area bass reflex openings, in conjunction with the housing
design, ensure optimized air flow and reduced flow losses, which not only
leads to a lower noise level, but above all to higher efficiency at low
frequencies.
The housing of the subwoofer consists of 18 mm thick birch plywood with
integrated steel braces. The MAIL SUB defies the tough everyday road life with
a hard-wearing polyurea finish. A total of six carrying handles ensure optimal
grip during assembly and disassembly. The optional MAILA SUB CB roller board
is the ideal choice for comfortable transport over long distances.
With LogoLink®, LD Systems has donated another innovation to MAILA. With the
free MAILA App (iPadOS), every MAILA system can be adjusted quickly, easily
and in detail and wirelessly supplied with software updates. Once connected,
the app automatically recognizes the existing MAILA components and enables the
system to be optimally set up before and during an event. The highlight: The
required wireless antennas are invisibly integrated into the LD logo of the
MAILA SUB.
MAILA APP (iPadOS)
The MAILA app for iPadOS is available free of charge in the App Store.
https://ld-systems.com/app-maila
CONSTRUCTION
The subwoofer has 6 ergonomic carrying handles that allow for comfortable transportation. Non-slip rubber rails are located on the bottom and on one side of the housing, so that the subwoofer can be placed both vertically and lying on its side. A connecting plate for the LD MAILA COL speaker column is located on the top of the subwoofer and one on the side opposite the side rubber rails. M20 threads for mounting the LD MAILA DB distance rod and for securing the MAILA COL speaker column are also located in the connecting plates.
DANGER:
Always place the subwoofer in a suitable place on a sufficiently stable, level
and horizontal surface. Make sure that the subwoofer or the speaker system
cannot fall off the edge of the stage (e.g. due to vibration).
