About the Evolution One TX 

From the top, the Evolution One comprises the TAD Coherent Source Transducer (CST), in which a tweeter is mated to a midrange driver in a coaxial arrangement. The CST comprises a 2.5cm beryllium-dome tweeter at the center of the magnesium cone of a 9cm midrange driver, the CST itself mounted in a shallow waveguide. These coaxial drivers together reproduce everything above 420Hz; below that frequency, the CST hands off to two 16cm woofers. These two drivers (as opposed to the single driver used in the Evolution Micro) are responsible for the extra bass extension of this design. Of particular interest here is the side-mounted sloted bass ports that effectively control turbulence and standing waves in the loading system when the speakers are delivering strong bass.

Then there is the outstanding level of attention to detail in the design and build of the drivers and cabinets. The speakers are not excessively heavy, in typical high-end stakes, but the careful design of shapes and bracing internally really controls cabinet resonance. And those drivers, built with the precision that TAD is famous for, are clean and precise with vanishingly low colouration. The whole combination really is an epic treat in terms of transparecy, imagery and tonality. The music just shines right through with no real effect of the speakers getting in the way at all.
