Mid-Range
The mid-range section is partnered with the high frequency on a custom designed one piece mid-high cast composite horn flare;-
With so much design effort concentrated on the vertical performance of arrays, the horizontal dispersion can sometimes be less
than ideal, with dispersion varying at different frequencies — particularly in designs that use coaxial, co-entrant or cross-firing
midrange arrangements for the mid/HF. MLA Compact has completely separate, mid and HF horns with horizontal constant
directivity characteristics — so the horizontal off-axis response tracks the on-axis response exactly. Martin Audio has over 30
years’ experience developing cone-driven midrange horns, and this experience, together with BEM optimised horn geometry has
been put to good use in the design of MLA Compact’s mid and HF sections.
The mid horn utilises 2 × 5"(125mm)/1.5"(38mm) voice coil neodymium drivers to produce 109dB @ 1m/2.83V — a big gain on
the typical efficiency of 102dB for cross-firing direct radiator designs in comparably sized systems. This is a result of painstaking
acoustic and thermal design, utilising forced-air cooling and a thermally conductive aluminium housing
The 5"cone/0.7"compression driver combination replaces the more traditionally used large format compression driver and has
less distortion, as well as having a much more extended HF response.
