<\/p>\nThe launch of the BE10 and BE20, Usher\u2019s 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\u2019s prowess in driver design, manufacturing and quality control.<\/p>\n

The DMD Midrange Driver Now, after years of rigorous research and experiments, Usher has finally successfully implemented the DMD technology on the 5\u201d midrange driver. This allows the music to be reproduced, from 385Hz up, completely by the amazing DMD drivers on both the TD-10 and TD-20. The result has to be heard to believe.<\/p>\n Woofer<\/strong> Crossover<\/strong> The TD-10 hosts one woofer per channel whilst the TD-20 employs two for even higher power-handling and larger listening spaces.<\/p>\n Specification : ________________________________________<\/p>\n The cosmetic condition of this beautiful and imposing pair of speakers is in excellent condition, as shown in the photos, and it is playing beautifully.

\n<\/strong>Diamond is almost a perfect material as driver diaphragm except for its high density (thus high mass) and brittleness. The few \u201cDiamond\u201d drivers that have been on the market all suffer badly from these two issues. Usher was the first, and still the only, to have solved these problems by inventing the DMD diaphragm, in which a super light metal base is sandwiched by amorphous diamond layers, resulting in a durable, light, fast, high-resolving and thus hugely musical tweeter: the Usher DMD tweeter.<\/p>\n![\"\"](\"https:\/\/hi-fi-spot.pt\/wp-content\/uploads\/2022\/01\/7-300x200.jpg\")

<\/p>\n
\nDue to the superlative performance of the DMD drivers, the 11\u201d German Eton woofer, with its super light yet super stiff honeycomb sandwich cone, was chosen to cover 385Hz and below for speed, resolving power and explosive dynamics.<\/p>\n![\"\"](\"https:\/\/hi-fi-spot.pt\/wp-content\/uploads\/2022\/01\/11-300x200.jpg\")
<\/p>\n
\nWhen developing the new DMD midrange driver, Usher has paid special attention to making sure that it would have a frequency response and impedance behavior that\u2019s effectively the same as those of the midrange it is replacing. This has made the new DMD midrange a drop-in upgrade for the current BE10 and BE20 owners. The crossover in the BE10\/BE20 Diamond was already optimized through countless hours of computer-aided design, measuring and actual listening for a seamless integration with both the DMD tweeter and the Eton woofer. With the efforts and attention in this regard put in whilst developing the DMD midrange, all that\u2019s needed to be done was to repeat the measuring and listening tests carefully to confirm the results remain optimal, which was exactly the case.<\/p>\n![\"\"](\"https:\/\/hi-fi-spot.pt\/wp-content\/uploads\/2022\/01\/10-200x300.jpg\")
\nTD-10 vs. TD-20<\/strong>
\nThe cabinets of the TD-10 and TD-20 are, per the Usher tradition, part of the whole system\u2019s integrated computer-aided and tested design, and are realized in an ultra-rigid, double reinforced, high inner-loss structure that\u2019s both low diffraction and low internal reflection. And again per the Usher tradition, the cabinets are finished in real wood\/real veneer and piano lacquer to the highest standards.<\/p>\n
