Both the closed-back DT 1770 PRO MKII and the open-back DT 1990 PRO MKII are equipped with two TESLA.45 drivers, each measuring 45 mm in diameter. The powerful neodymium magnet achieves a flux density of over one Tesla in the voice coil air gap, resulting in particularly strong driver performance.
Thanks to the structurally optimized diaphragm, the level of distortion and impulse response has been significantly improved compared to the previous model, leading to a clearer sound profile. The diaphragm, made of high-performance PEEK polymer, ensures precise bass reproduction, while the refined treble profile is achieved through a lightweight voice coil made of aluminum-coated copper wire.
The newly developed system combines flexibility and exceptional sound quality due to the use of modern materials and manufacturing techniques. With an impedance of 30 ohms, both models are suitable for a wide range of devices, providing reference-quality sound that meets the needs of professional users.
