Refined Minimalist Design
The Studio 9 design will satisfy existing Harman Kardon Onyx series fans as well as new users. The product displays a minimalist design which designers created with precise craftsmanship.
The Studio 9 maintains its round shape while its new metal frame design functions as a safety “belt” which protects the speaker and works as a handle and base for the complete system design. The Studio 9 refinement provides an elegant appearance which remains compact yet impressive in all environments.
The Onyx Studio 9 silver metal frame consists of 90 recycled aluminum which has been transformed into a smooth finished product. The speaker body features Kvadrat fabric which covers both its front and back parts, delivering a beautiful appearance and smooth texture while protecting against dust. The front panel displays a minimalist design which uses a small Harman Kardon logo to create an elegant appearance that achieves both simplicity and sophisticated balance.
The Onyx Studio 9 metal frame above the physical buttons contains power Bluetooth volume up/down play/pause and Auracast activation buttons. The seamless layout enables users to operate the system without difficulties. Harman Kardon achieves its attractive design through “hiding” elements which lead to recessed physical buttons that stay flush with the frame color yet need users to observe them closely during their first experience with the product.
