It has been over a year since Future Sonics announced the Atrio rev2, now the company is planning to upgrade the dynamic transducers on both their Atrio and Ear Monitor series. Atrio, which based on the MG5pro 10mm dynamic transducer will have a new MG7 driver, while Ear Monitor will upgrade its aging MG4+ transducer to the new 13mm MG6pro driver. While the transducers' size remain the same for both drivers, it is said that the new drivers will have better headroom and treble performance in comparison while still retaining Future Sonics unique sound signature. It seems that Future Sonics has no plan for now to turn the upgrading into a big event, but you can expect the packaging to change when the upgraded models hits the street.
