The rear bracket swings up as the MLA to join to an array but links to one position to give an angle of 13.75⁰. There is only
a
single hole in the bottom of the bracket to accommodate a second MLD in the array which will give a fixed angle between the
two of 20⁰.
Acoustic Design
The acoustic design of the MLD matches that of the MLA with the dispersion characteristics the only difference. The same drivers
are used throughout. It is also an all horn loaded three way enclosure.
Low Frequency
The low frequency section is virtually identical to MLA featuring the same 12"neodymium drivers in a twin Hybrid® horn loaded
configuration. In spite of the different enclosure size and shape the same low frequency output has been achieved delivering
133dB continuous and 139dB peak (Measured in half-
space at 1metre with a tone burst signal, then referred back to open (4π)
space) to match the MLA providing excellent low frequency coherence. The drivers are front loaded onto a hyperbolic horn with
the rear chamber also reflex loaded to achieve extended low frequency response below the cut off of the horn. The low frequency
response of the MLD matches the MLA reaching down to 52Hz, often making subs unnecessary for certain applications.
Mid-Range
The horn loaded mid-range uses the same 6.5"neodymium magnet drivers as the MLA. It also uses the same patented toroidal
phase bung to smooth the mid horns frequency response. Wave propagation in the horn throat is smoothed by the Martin Audio
HiBlade
™ device. The mid horn however has a 120⁰ horizontal and 20⁰ vertical dispersion pattern.
High Frequency
The High frequency section utilises the same configuration of three 1"neodymium magnet compression drivers as the MLA but
fitted to a 120⁰ horizontal and 20⁰ vertical dispersion horn.
