Harman Kardon Onyx Studio 9 Grey — 50 W Portable Bluetooth Home Speaker

Three-channel 50 W RMS sound with a built-in battery for up to 8 hours of music anywhere at home.

The Harman Kardon Onyx Studio 9 Grey is a portable Bluetooth home speaker rated at 50 W RMS, built around a three-channel layout: one 120 mm woofer and three 20 mm tweeters. A built-in Li-ion battery delivers up to 8 hours of playtime, while the aluminium frame works as both handle and stand. The box includes the speaker, a power cable and documentation.

Constant Sound Field for a wider soundstage

Harman Kardon Onyx Studio 9 uses a dedicated centre channel for crystal-clear vocals, flanked by two tweeters that widen the soundstage. Music fills the room around you instead of firing from one spot, which suits open living areas.

Self-Tuning: automatic room calibration

Every time you power it on, the Onyx Studio 9 calibrates itself to its surroundings (Self-Tuning adjusts the sound to nearby walls and surfaces). Move the speaker from kitchen to balcony and the balance stays right, with nothing to adjust.

Built-in battery and aluminium handle

The Harman Kardon Onyx Studio 9 runs up to 8 hours on its built-in battery and recharges in 4 hours. The integrated aluminium frame doubles as handle and stand, so you can lift the speaker with one hand and carry it room to room.
