Product information

Description

The Harman/Kardon Onyx Studio 9 is a round stereo portable speaker with a 50 W RMS output in black and grey. It features a 12 cm woofer and a 2 cm tweeter, supporting a frequency response from 50 Hz to 20 kHz and a signal-to-noise ratio of 80 dB. The speaker offers wireless Bluetooth connectivity, a USB Type-C port, and a 2 m cord for charging. Its lithium-ion battery (approximately 4722 mAh / 17.15 Wh) provides around 8 hours of playback. The design is compact and intended for universal audio use.

Advantages

The Onyx Studio 9 combines a 50 W RMS output with a balanced woofer and tweeter configuration to deliver clear mid and high frequencies and robust low end for its size. Wireless Bluetooth and USB Type-C connectivity make it simple to pair devices and recharge the battery. The round, portable design and multi-hour battery life support mobile use in different environments.

Suitable for

  • Listening to music at home or outdoors
  • Portable audio for small gatherings
  • Streaming MP3 and other common audio formats from Bluetooth devices

When it may not be suitable

This speaker is designed for portable and home use and may not meet the power or coverage requirements of large venues or professional sound reinforcement. Users seeking very long continuous playback beyond the listed battery life or advanced audiophile features such as lossless wired inputs or studio-grade monitoring may find it limiting.

Key specifications

  • Output power: 50 W (RMS)
  • Frequency range: 50 Hz – 20 kHz
  • Signal-to-noise ratio: 80 dB
  • Drivers: 12 cm woofer and 2 cm tweeter

  • Cable length (charger): 2 m
  • Colour: Black, Grey
  • Design: Round, portable stereo speaker

How to use

Charge the speaker via the supplied USB Type-C cable before first use. Pair a Bluetooth device by enabling Bluetooth on your source device and selecting the Onyx Studio 9 from the device list. Adjust volume and playback from the connected device or speaker controls as available. For wired charging, connect the USB Type-C cable to a compatible power adapter. Observe the indicated battery runtime and recharge when battery level is low.

What to consider before purchase

  • Intended use: portable/home listening versus large venue sound
  • Battery runtime versus your typical playback duration
  • Need for wired inputs or advanced audiophile features
  • Preferred connectivity options (Bluetooth, USB-C)

Usage recommendations

Place the speaker on a stable surface away from obstructions for best sound dispersion, keep the firmware updated if updates are available, and charge the battery fully before extended use to maximize playback time.
