Acoustic Design

The MLA system uses a highly sophisticated combination of software and DSP to achieve outstanding coverage however the
acoustic system still needs to perform to the highest level; DSP cannot cure a poorly designed speaker. Acoustically, MLA raises
performance to a new level – with increases of 5dB in low frequency output, 10dB in mid frequency output and 10dB in high
frequency output over existing, comparably-sized designs.
In common with many Martin Audio concert sound products, MLA is an all-horn loaded, 3-way design with an exceptionally
smooth frequency response - both on and off-axis. In contrast to systems which utilise direct radiators for the lows and mids,
MLA's all-horn design ensures that lows and mids are able to keep up with the very high efficiency HF section. MLA deliberately
avoids the use of coaxial, co-entrant or cross-firing midrange/HF driver arrangements which introduce acoustic discontinuities
that affect the on and off-axis frequency response of both mid and HF sections. The MLA's mid and HF horns are completely
separate – a key factor in MLA's ability to produce consistent, true 90° horizontal constant directivity coverage. This gives
startlingly consistent frequency response when listening off-axis and "walking the field".
Sonically, MLA delivers power, clarity and detail to over 150 metres. Its peak output capability of 140dB LF, 139dB midrange and
145dB HF, per box at I metre, is huge.
