Voltric 70 E-tune: Yonex’s first E-tune, and Ratchanok’s racquet at world No. 1
Three titles in three weeks
In April 2016 Ratchanok Intanon won the India Open, the Malaysia Open and the Singapore Open on three straight weekends, and Yonex listed the Voltric 70 E-tune as her racquet. She beat Li Xuerui 21–7, 21–18 in the India Open final and came from a game down to beat Sun Yu 18–21, 21–11, 21–14 in Singapore. The run made the 21-year-old Thai world No. 1 for the first time, on the ranking of April 21. Yonex’s table of Hawk-Eye smash speeds for that season put her at 372 km/h at the Malaysia Open, the fastest of the women it listed. Days after reaching No. 1 she played badminton with Thailand’s prime minister, and Yonex noted that the two used her Voltric 70 E-tune.
E-tune: seven set-ups from one frame
Yonex announced the Voltric 70 E-tune on August 19, 2014, for worldwide release that September, at ¥22,000 before tax in Japan. It was the first racquet with E-tune, short for Energy Tune. Parts supplied with the racquet fit the top of the frame, the bottom or both, and in Yonex’s machine tests they raised power by 6%, 4% and 10% over the bare frame. Yonex said the top parts help the head drive a smash and the bottom parts keep the racquet quick in fast rallies. Optional tungsten parts, E-tune Parts 1, cost ¥650 before tax and added three more set-ups; with the bare frame that made seven, which Yonex billed as a world first by its own survey. The frame was new too. Yonex credited new linked grommets with 3% more power than the previous Voltric 70 and listed high-modulus graphite with Nanometric and tungsten in the frame, Ultra PE fiber in the shaft, and a new built-in T-joint with T-Anchor.
From Maeda’s bronze to Gideon’s three titles
Yonex had players on it before it reached shops: Miyuki Maeda used it when she and Reika Kakiiwa took bronze at the August 2014 World Championships. Ratchanok was on it by the December 2014 Superseries Finals and was still listed on it when she lost the March 2017 All England final to Tai Tzu Ying. Akane Yamaguchi, on the Voltric 80 E-tune in spring 2015, won the 2015 Bitburger Open and the 2017 German Open with the 70. In doubles, Marcus Fernaldi Gideon had it when he and Kevin Sanjaya Sukamuljo, on an ArcSaber 11, won three Superseries in a row in March and April 2017: the All England, 21–19, 21–14 over Li Junhui and Liu Yuchen, then the India Open and the Malaysia Open. Hong Kong’s Tang Chun Man won the 2017 Denmark Open mixed doubles with it, partnering Tse Ying Suet, and Yonex Japan still listed Korea’s Chae Yu-jung on it when she and Seo Seung-jae won the German Open in March 2019.
White frame, orange parts, a red sibling
Yonex sold the 70 E-tune in one color, white, made in Japan, in 4U and 3U, and rated it medium flex. Yonex recommends 19–24 lb for the 4U and 20–25 lb for the 3U. Its own literature calls the tuning pieces simply parts. UK coach Paul Stewart, who fitted them, described throat pieces that pop in and out like grommets and a strip for the top of the head whose pins slot into the existing grommet strip; in retailer photos the supplied set is orange. Yonex Japan also sold a dedicated black-and-orange grommet set for the frame. In March 2015 a second E-tune racquet followed, the stiffer Voltric 80 E-tune in Deep Red, with its own optional E-tune Parts 2. The 70 E-tune replaced the plain Voltric 70, which has its own page, and it is a different frame, not the old one with parts added; Carsten Mogensen, who had won with the original, was listed on the E-tune in 2016 and 2017. No player or limited edition of the 70 E-tune is documented.
Four years in the range
Yonex Japan listed the 70 E-tune from its September 2014 launch until at least June 2017, and it was gone from the list by October 2018. Yonex’s global product page went offline in April 2018, though Yonex Japan’s own page stayed up into 2019. It was a regular-production frame played in clubs as well as on tour, so the verified sales recorded so far are all pre-owned, from Asia resale; the price panel above shows them. Two identity points matter in listings. Many say only “Voltric 70,” and the plain 2010 model is also white, so a sale needs the E-tune named, the parts shown or a photo of the shaft. And a used frame may come without its parts, so ask what is included.
Fakes and look-alikes
No counterfeit specific to the Voltric 70 E-tune has been documented. The Voltric fake described in most detail is the Z-Force, copied within a year of its 2012 launch, so Yonex’s general checks apply. The practical risk is a mix-up. The plain Voltric 70 shares the name and a white finish but is a different frame, and the Voltric 7 and 5 share the family look but were made in Taiwan. The parts are model-specific: Yonex sold E-tune Parts 1 for the 70 and Parts 2 for the 80, and gave each racquet its own grommet set, so a kit offered with the frame should match it.
A different racquet, not an add-on
Paul Stewart gave the 70 E-tune four stars, calling the parts gimmicks but the racquet good, and warned buyers not to expect the original Voltric 70 with extras: he found it a completely different feel and spec, and less quick at the net than he remembered the original. On a Japanese user-review site it has scored higher than the 80 E-tune for swing and control. Its tour record sets it apart from most Voltrics below the flagship: a world No. 1 run, an All England men’s doubles title and Superseries titles in singles and doubles in 2016 and 2017. Two more E-tunes followed in early 2016, the Taiwan-made Voltric 50 E-tune and Voltric 8 E-tune; each has its own page. In 2017 both Ratchanok and Gideon moved on to the new Astrox 77.
Yonex’s item code is VT70ETN; Asian-market labels may add SP, a distribution code. Yonex sold it only in white, made in Japan, rated medium flex, in 4U (average 83 g) and 3U (average 88 g), each with grip 4 or 5. In retailer photos the shaft reads “VOLTRIC 70” followed by an E-tune logo. A complete set includes the parts Yonex supplied for the top and bottom of the frame; in retailer photos they are orange, two long strips and two small throat pieces. E-tune Parts 1 were sold separately. A white Voltric 70 without these features may be the plain 2010 model (code VT70). Yonex’s checks: a hologram sticker that resists peeling and a laser-engraved production code on the cap above the handle.
The first E-tune and the racquet of Ratchanok’s 2016 rise to world No. 1, with an All England men’s doubles title besides. Confirm it is the 2014 E-tune and not the plain 2010 Voltric 70: look for the code VT70ETN or the E-tune logo on the shaft, and ask whether the parts are included. Check the head and throat for cracks around the grommets, and treat any claim that a frame was a named player’s match racquet as unproven without documentation.
