Harman Kardon Onyx Studio Technical Specs
Audio and Performance
- Transducers: Features two 3-inch (75mm) woofers, two 3/4-inch (20mm) tweeters, and two rear-firing passive radiators for extended low-frequency response.
- Output Power: Delivers 4 x 15W (60W total); similar to its siblings, it uses a bi-amplification strategy to ensure dedicated power delivery to each frequency range.
- Frequency Response: Ranges from 60Hz to 20kHz, maintaining a high maximum SPL of 95dB @ 1m, which is significant for a portable unit of this size.
Connectivity and Control
- Bluetooth 3.0: Supports A2DP v1.3 and AVRCP v1.5; unlike the flagship Onyx, the Studio version removed Wi-Fi, NFC, and Aux-in (on the original model) to simplify the user interface.
- Minimalist Interface: The top rim features tactile rubberized buttons for Power, Bluetooth pairing, and Volume control, intentionally avoiding the complex touch-capacitive sensors found on the leather-wrapped original.
- Micro-USB Port: Located on the rear, this port is strictly for firmware updates and service, not for audio input or charging.
Power and Battery
- Battery Configuration: Equipped with a 3.7V, 2600mAh cylindrical Lithium-ion cell, providing roughly 5 hours of playback depending on volume levels.
- Power Supply: Uses a 19V / 2.0A AC adapter; it is important to note that the amplifier logic typically throttles output to 4 x 7.5W (30W total) when running on battery to extend playtime.
- Charge Time: A full recharge from 0% takes approximately 5 hours using the provided power brick.
Dimensions
- Weight: 4.6 lbs (2.1 kg).
- Dimensions (Dia x W x H): 11.0 x 6.3 x 10.2 inches (280 x 161 x 260 mm).
