USHER TD-20
A True Speaker Manufacture
In the Swiss watch industry, the term manufacture is used to refer to a watchmaker/brand who designs and manufactures its watches almost completely, as distinct from an atelier de terminage, which is concerned only with assembling, timing, fitting the hands and casing an externally-sourced movement. Some famous examples of manufacture are Patek Phillipe, Rolex and Jaeger LeCoultre.
In the loudspeaker industry, the ability to design and manufacture the heart of the whole speaker system—namely the speaker drivers—also separates the real technically capable from the rest. In this sense, Usher is one of the very few true manufactures in the high end speaker world.
The launch of the BE10 and BE20, Usher’s then flagship speaker systems, and a few years later, their successors the BE10 Diamond/BE20 Diamond with the ground-breaking DMD tweeter, have show-cased Usher’s prowess in driver design, manufacturing and quality control. With the new DMD (Diamond-Metal-Diamond) midrange driver—that’s on the TD-10 and TD-20—Usher has again pushed speaker driver technology to a new height.
