User manual AUSTRALIAN MONITOR DOUBLE 15 BROCHURE

[. . . ] -a o -I f THE CONCEPT The Qmx DOUBLE 15 is the first in a new generation ofAustralian Monitor high power loudspeakers. Qmx is the culmination of many years of rcseiuch, development and practical 'hands on' experience in high power sound reinforcement systems and their applications. The unique concept of Qmx provides all that is rcquired to achieve in dynamically accurate high fidelity performance. Qmx provides unifom wavefront coupling, enhanced phase coherence in the cross-over region, constant dircctivity, stable the optimum beamwidth and yet is capable of delivering SPL a maximum on axis peak of l36dB. A11 achieved without expensive electronic trickery or special equalizers compensating for speaker inadequacies or bad cabinet designs . THE SYSTEM A full range loudspeaker system, the Qmx DOUBLE 15 features a two way, long throw, quasi bandpass vented enclosure with physical alignment of driver acoustic centres fbr accurate signal syrchronization. [. . . ] The hom is moulded in high density structural polyurethane to eliminate vibration and resonance. I I vEltTIttAL HoRrzo\hL uoooH. 2oooH/ NETWORK MANAGER The heart ofthe Qmx system is the Network Managcr, a sophisticated proprietary clesign circuit. and the end product of many hundreds of man hours of intense devclopment and critical listening tests. The Network Manager's primary task is thrt of a passive filter network: however, within the Qnrx desigl concept ali is not as simple as it may appear. Various other Australian Monito special duties are handled by the Qnx Network Manager such as: inpedance corleclion, divcrtransient/antplitude response control, and hur management. The resulting smooth liequcncy rcsponse and phase cohcr- ent acoustical poirt sourcc provide solid imrging, cladty, detail and defilition rhar has to be expcricnced to be believed. CONSTRUCTION Thc ru-eged cabinet of the Qmx DOUBLE I 5 is constructed in 18mnr structural grade. Being an cssentially modular co1]structioi], self bracing is intrinsic to the design.
