NEW TWEETER UNITS
High-frequency drive units require extremely consistent parts and manufacturing in order to be selected for a Mission speaker. Given the tiny moving masses involved, one micro-drop extra of high-tech adhesive candestroy the balance of the design, thus affecting sensitivity and frequency response. For the LX Series, Mission has meticulously designed a tweeter with a neodymium magnet, selected for maximum magnetic force in a small space, and a 25mm microfibre dome, chosen for its repeatability and consistency in manufacture. It delivers sweetly incisive upper frequencies, crisp and detailed but never harsh.
Both the LX-2 and LX-3 are two-way designs, combining the 25mm tweeter with one 130mm mid/bass drive unit in the LX-2, and two such units in the LX-3. These drivers sports cones fashioned from an advanced fibre formulation, selected for its reduced susceptibility to hygroscopy as well as being very stiff for its mass with excellent self-damping. A high-strength ferrite magnet ensures that the magnetic field is directed precisely within the area of voice coil excursion, enabling an ultra-linear performance that minimises colouration.
The LX Series uses a 4th order (24dB per octave acoustic) Linkwitz-Riley crossover network, developed
through a combination of advanced computer modeling expertise and many hours of listening tests. It is
particularly notable for its ability to balance excellent off-axis performance with a flatter on-axis result.
The cabinet is as critical as the drive units and crossover to the overall performance of any loudspeaker system. Designing an effective low-cost box is tricky, as budget dictates that the designer can’t use expensive materials or high mass to create an inert structure.
With the help of 3D Computer-Aided Design, finite element analysis and laser interferometry, coupled with a great deal of experience, a budget cabinet can be designed that delivers better rigidity with lower radiated noise than most designers would believe achievable at such low material cost.
