Yonex Voltric technology performs in a variety of ways. The stiff racket structure at the top of the frame head allows the head to bend in a very controlled way & hold shuttles on the string bed for longer. The thin frame sides then allow the frame to flex more & transfer more energy to the shuttle. This combination means that you can smash with instant power. This is the top end of the Voltric series, with a stiffer frame section & the most head-heavy balance. To balance the heavy head the frame has been made smaller to maintain a fast & powerful swing. Meanwhile, the weight is balanced on the top of the frame & at the joint area which allows good handling while also maintaining power. The thin sides of the frame & at the top of the head reduced air resistance & improve the handling even further. Players can now make a full swing even during short range rallies as VOLTRIC responds instantly to even subtle movements. Another innovative Yonex technology, Sound Filter, uses new materials at the two & ten oclock positions to reduce only high pitched & dull sound waves. This produces a louder & sharper sounds on impact to unsettle opponents, & provides a more aggressive tone to your game for a relentlessly attacking style of play. This racket also features the new Yonex single-pass grommet hole construction, providing more grommet holes at the 2 & 10 oclock position on the frame, creating a high performance stringing pattern that increases durability by 7%. The new lightweight built-in T-Joint is made from an epoxy resin material that enhances your level of performance by increasing the stability of the shuttle on the string bed & through the air. The Control Support Cap has been made even thinner to further reduce friction through the air, while still providing precise racket control allowing maximum manoeuvrability. To top it all off, the Isometric Square.
