Key Features
RS165 Mid-Woofer
Built with an aluminum-magnesium alloy cone and a large motor structure, the RS165 delivers powerful midbass performance with improved speed, clarity, and control. Compared with the RV165, the RS165 responds more quickly to dynamic musical passages while maintaining excellent low-frequency authority.
RS90 Midrange
The RS90 is designed to reproduce vocals and instruments with exceptional clarity and detail. Compared with the RC90, it delivers greater detail retrieval, improved articulation, and a brighter, more revealing presentation, allowing subtle musical nuances to emerge more clearly within the soundstage.
RS28 High-Resolution Tweeter
Featuring a high-density silk diaphragm and neodymium motor structure, the RS28 reproduces high frequencies with outstanding detail, openness, and refinement. Its spacious presentation helps create a larger and more immersive listening environment while preserving long-term listening comfort.
True 3-Way Component Design
The dedicated woofer, midrange, and tweeter configuration ensures precise frequency distribution and improved acoustic integration, helping the RS6.3 achieve superior imaging and instrument separation.
Performance Highlights
The RS6.3 is engineered for listeners who value accuracy, detail, and realism. Faster midbass response, higher vocal resolution, and a spacious treble presentation combine to create a highly transparent and revealing sound signature capable of reproducing complex recordings with confidence.
Application
