After launching on the market in 1978 the iconic 770 speaker and, two years later, the more compact 700, the British speaker system specialist Mission continued its particular journey to become a decisive player in the audio sector. British High Fidelity. Thus, in the decades of the 80s and 90s he played a crucial role in the popularization of so-called “shelf” models, which were easy to accommodate in any domestic space, while being equipped with impressive engineering that would allow it to display a captivating sound. In recent years, Mission has explored its rich archive in order to reimagine some of his successes originals, especially the 700 and 770 models, not simply appealing to nostalgia, but redesigning them to the point of making them exceptional by modern standards. Now it's the turn of the 750, a compact monitor inspiration too “retro”but which, unlike the aforementioned 700 and 770, does not constitute the updating of an achievement from the past.
Measuring 355 mm high by 216 mm wide and 270 mm deep, the new Mission has an aesthetic that fits perfectly with that of its older sisters, highlighting, as in the 700, the arrangement of the two speakers that it incorporates, by placing the treble one below the mid/bass one. This configuration answers the name “Inverted Drive Geometry” (Inverted Transducer Geometry) or IDG and aims to place the “midwoofer” closer of the height of the ear with the tweeter below, equalizing the acoustic centers of each other in this way the sound waves coincide in the listener's head, consequently improving the stereo image and contributing to the consistency and transparency global sound. Going into the technical details, let us first note that the mid/bass transducer mounts a new polypropylene cone (a material whose use in commercial speakers Mission pioneered) of 135 mm in diameter, filled with minerals in order to increase its rigidity and achieve particularly fast, deep bass and firm via bass-reflex configuration with rear port.
This is helped powerfully by custom made magnetic motora chassis of molten metal and a peripheral suspension low-density nitrile, in which the connection with the diaphragm has been carefully studied to achieve a perfect impedance match and reduce reflections from the cone contour. For his part, the tweeter features an ultra-light 28mm microfiber dome and exceptionally linear response reinforced by a rear chamber which places its fundamental resonance frequency well below the cut-off region. A crucial role in the behavior of the 750 is undoubtedly played by the crossover filterfine-tuned with the help of software measurement and mapping techniques and in it the use of minimized paths and very high quality components (polypropylene capacitors, coils with air core) stands out. Finally, let us note that the enclosure (an optional floor stand is available) includes strategically placed internal reinforcements and is constructed with MDF panels of high density and chipboard glued together by a layer of highly cushioning adhesive.
