Drawing on seven decades of professional audio engineering excellence, JBL’s One Series 104-BT reference monitors bring studio-grade accuracy to content creators, musicians, podcasters, and producers in a compact desktop format. These innovative speakers feature a groundbreaking coaxial driver design with a high-frequency driver precisely aligned with a contoured woofer cone, providing exceptional detail and neutral sonic presentation across a wide sweet spot. The acoustically optimised cabinet includes a precisely contoured low-frequency port that works with the driver to provide accurate bass response down to 60 Hz, impressive for monitors of this size.
The 104-BT models feature Bluetooth 5.0 wireless streaming alongside traditional wired connections, giving audio professionals the flexibility to reference their mixes across different playback methods. Clean 60-watt Class D amplification distributes 30 watts per speaker, enabling the monitors to reach 104dB SPL peak levels without the distortion typically found in comparable desktop monitors. This power handling makes them suitable for both critical listening and louder playback scenarios.
Designed with modern production workflows in mind, these reference monitors include practical features like front-panel volume control for convenient adjustments, an automatic speaker-muting headphone jack for instant isolation, and multiple input options including dual 1/4-inch balanced TRS, single 1/8-inch unbalanced TRS, and Bluetooth connectivity. The front panel selector allows seamless switching between inputs or keeping them all active simultaneously, while the compact form factor and sleek aesthetic make them ideal for smaller workspaces without compromising on JBL’s legendary professional audio quality.
