[The top-of-the-line flagship model of Radius' symbolic [Doburube series]] HP-TWF41 uses a beryllium-coated diaphragm in the woofer section that reproduces mid- and low-frequency bands. This expands the high frequency reproduction band to the point where a tweeter is not required, and also realizes extremely stable and crisp low frequency reproduction. By combining this beryllium-coated diaphragm with a high-performance Taiyo Yuden piezo diaphragm with excellent transient characteristics in the high frequency band, the thickness of the wide range of sound and the reproducibility of high-resolution sound sources have been dramatically improved.
[DDM method driver] The DDM method (Dual Diaphragm Matrix) driver is a completely new driver method unique to Radius that distributes mid-bass and high-range sounds to two independent diaphragms and arranges them on the same axis. The HP-TWF41 uses a beryllium-coated diaphragm in the woofer section that reproduces medium and low frequency bands.
[Uses a Taiyo Yuden piezo diaphragm] In order to reproduce the detailed high-frequency range of high-resolution sound sources, a Taiyo Yuden piezo diaphragm with a ceramic layer is used. The ceramic layer (piezo) vibrates firmly even when a minute sound source signal is input. It clearly depicts high-definition sound and atmosphere.
[Compatible with MMCX re-cable] The head part of the earphone is compatible with MMCX connector re-cable, so you can change to your favorite cable and enjoy the difference in sound quality. Even if the cable breaks, you can use the earphones for a long time by simply changing the cable.
