The newly developed STELLAR .45 driver delivers premium, distortion-free sound at high volume levels, compatible with any playback device. Professional Audio Quality: Reliable Studio Sound Meets High Performance. Developed and manufactured in Heilbronn, Germany, the STELLAR.45 delivers studio-class performance while delivering renowned Beyerdynamic sound. Featuring a neodymium ring magnet and high-tech copper-clad wire, the STELLAR.45 offers an unparalleled trade-off between conductivity and wire weight. The combination of a newly developed three-layer speaker diaphragm and damping layer creates a highly efficient driver system that delivers outstanding performance on any playback device. Additionally, an innovative membrane structure controls the axial movement of the voice coil, ensuring the voice coil is positioned securely within the magnet gap, even under high vibrations. Another benefit is the expansive, natural frequency response. The lightweight coil's fast response and precise transient response ensure a distortion-free sound, even at high sound pressure levels.
