A stylish portable premium-level acoustic system with powerful, balanced sound, advanced wireless capabilities, and a power bank function for charging mobile devices. It features a signature design with a distinctive round shape body and a built-in aluminum handle, making it extremely convenient to carry the 3-kilogram speaker. Despite the impressive size, the device remains a mobile solution for those who value uncompromising sound quality in any condition.
The manufacturer positions it as a flagship product model of the year 2025, aimed at demanding users ready to invest in premium sound for home, office, or outdoor events. The portable speaker Harman Kardon Onyx Studio 9 is equipped with a thoughtfully designed acoustic system: a 120 mm woofer provides deep bass, three 20 mm tweeters ensure detailed high frequencies, and a passive radiator boosts the low-frequency range without additional energy costs.
The total power of 50 W allows sound coverage for an area up to 40 m² or to organize quality sound support at an open venue. The frequency range of 50-20000 Hz covers the full spectrum of audible frequencies, which is especially important for classical music and live recordings. The modern Bluetooth 5.3 module with multipoint support enables connecting two devices simultaneously and switching between them without reconnection.

Frequency Combination
The Harman Kardon Onyx Studio 9 Bluetooth speaker provides balanced sound, revealed across a wide frequency range due to the combination of multiple speakers. The design features a 120mm subwoofer, creating powerful rhythms for any party and rich bass for open spaces. Three 20mm tweeters are directed in different directions, forming an immersive premium stereo sound that highlights vocals and emphasizes instruments across any music genre. The "Constant Sound Field" technology ensures a detailed and rich acoustic scene, suitable for dancing, movie watching, gaming, or listening to audiobooks. Complementing the system is a passive radiator, providing an effective alternative to a bass reflex. The combined power reaches 50W — a confident average for portable audio systems. It is worth noting separately the ability to adjust high frequencies and bass through a combination of buttons.
Convenient Integration
The portable soundbar easily fits into the home environment — both visually and functionally. Compared to previous generations, the body has become more cohesive and practical, though it remains weighty (3.3kg). The aluminum ring at the bottom expands into a stable stand with a rubber coating, and a handy carrying handle is hidden at the top. The form factor is optimal for placing on flat surfaces, though it may show instability on grass. Upon each activation, the system automatically calibrates the sound by analyzing the surrounding space, and the "Harman Kardon One" app provides access to advanced settings. Key features include combining compatible speakers into a unified system through TWS and "Auracast." The "Multipoint" mode is also supported, allowing you to connect two devices and quickly switch between them. The built-in 4722mAh battery provides up to 8 hours of playback and can slightly charge mobile devices via the USB-C port.
