The MLA3-2i is a 3-way, axisymmetric large format line array system designed specifically for permanent installation. The system is engineered to deliver high definition, high SPL sound reinforcement for a broad range of applications, including concert halls, stadiums, and large clubs.

Each MLA3-2i line array cabinet features two manifold loaded 12" McCauley 8231 Low-Mid drivers, two 77087 8" Midrange Drivers and two 1" exit compression drivers on a 90° x 10° slot-loaded wave guide.

The McCauley 8231 Low-Mid driver is built around a new field serviceable motor with integrated aluminium heat sink. The new motor design has a thinner, 0.3" top plate and longer 0.9" by 4" diameter aluminium coil which improves the linearity of the Bl vs. displacement profile. The 8231 Low-Mid driver features a hybrid composite-paper cone which balances light weight and high stiffness, to improve overall sensitivity, with the internal damping that is inherent to paper cone loudspeakers.

The coupling of the cone drivers and high frequency waveguide has been specially engineered to produce a rich and fully balanced sound from 50Hz to 18kHz. The 8231 12" low-mid drivers are manifold loaded to improve the sensitivity over their operating band and increase array density. The 77087 8" midrange drivers are phase plug loaded to match the pattern of the HF around the crossover frequency and reduce cabinet to cabinet interferences. The HF slot loaded waveguide is optimized to reduce resonances which would require DSP equalization. The sensitivity of each component has been specifically engineered for the MLA3-2i to allow for the extra HF headroom which is often required in longer throw applications.
