DOUBLE L2
Provisional
Specification
The Qmx DOUBLE 12 is the second product from Australian Monitor utilising the highly successful Qmx
concept.
The Qmx concept is the culmination of many years of research, development and practical "hands on"
experience in high power sound reinforcement systems and their applications. The unique concept of Qmx
provides all that is required to achieve the optimum in dynamically accurate high fidelity performance. A full
range loudspeaker system, The Qmx DOUBLE 12 features a two way, long throw, quasi bandpass dual ported
enclosure with physical alignment of driver acoustic centres for accurate signal synchronisation. Qmx provides
uniform wavefront coupling, enhanced phase coherence, constant directivity, stable beamwidth and is capable
of delivering a maximum on axis peak SPL of 133d8. All achieved without expensive electronic trickery or
special equalisers compensating for speaker inadequacies or bad cabinet designs. Compact and easily
manageable The Qmx DOUBLE 12 is suitable for flying or stacking, allowing high packing densities in
confined areas.
