The Nano Tube™ runs as a common thread through both the Satin and Karma, giving them a shared low-end foundation. Whatever the driver configuration above it, this platform delivers ultra-linear bass: deep, controlled, and phase-coherent, with real weight and texture rather than bloat. The result is bass you can trust across the entire family. Move between models and the foundation stays honest, the low end resolving with the same authority and articulation every time.
