KFD AC Adapters LAC-029-US Editorial Review

The KFD AC Adapter for Harman Kardon Onyx Studio Speakers is a reliable and affordable power supply cord. It charges the speaker as described and fits perfectly. The connector size is 5.5 mm in diameter. It is compatible with the HK Onyx Studio 1 and works well with the Onyx Studio 4 and 5. However, it may not work with the Onyx Studio 7 and Aura Studio models.
