Trust the Transparency
Great mixes start with honest mix references. With JBL 104-BT, you’ll hear the content you’ve created in true clarity and detail, with none of the coloration that can compromise your mix decisions. 104-BTs are optimized for desktop placement, and their smooth off-axis response means you can reference your mixes confidently across a wide sweet spot.

Pro Performance, Scaled to Size
The world’s top recording studios and touring artists rely on JBL Professional monitors to deliver unparalleled fidelity and performance. With our 1 Series, we’ve optimized that technology in our smallest form factor ever. The 104-BT Reference Monitor’s innovative coaxial driver design features a high-frequency driver aligned with a woofer cone precisely contoured to deliver accurate response, exceptional detail and impressive off-axis performance. The result: neutral, accurate sound, anywhere. The cabinet’s precisely contoured low-frequency port works with the driver to deliver powerful, tight bass at any volume level.

The Bluetooth Advantage
The 104-BT offers the convenience of Bluetooth streaming, which gives audio engineers the ability to check their mixes over Bluetooth to ensure they translate well to common listening scenarios.

Power and Punch
The JBL 104-BT Reference Monitors’ integrated 60-watt Class D power amplifier distributes a potent 30 watts per speaker.

JBL 104-BT Reference Monitors integrate smoothly into any production workspace, thanks to smart features like a front-panel input control that selects Bluetooth, Aux, RCA, TRS or combines all inputs—quickly check references or switch easily between tasks like playing back your tracks and taking a phone call. Or, select all inputs for a simple mix. Front-panel volume control allows convenient level adjustments without straying from the sweet spot, and a front-panel headphone jack automatically mutes the speakers, giving you isolation in one simple step. And, JBL 104-BT Reference Monitors’ dual 1/4-inch balanced, dual RCA and single 1/8-inch inputs accommodate a wide range of signal sources.
