Trust the Transparency

With JBL 104 Reference Monitors, you’ll hear true clarity and detail, with no coloration. The 104s deliver crisp highs and rich bass just as intended.

They’re optimized for desktop placement, with neutral low-frequency performance. And their smooth off-axis response means you can monitor with confidence in 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. Now, we’ve optimized that technology in our smallest form factor ever. The 104 Reference Monitor’s innovative new coaxial driver design features a high-frequency driver aligned with a precisely contoured woofer cone to deliver accurate response,

exceptional detail and impressive off-axis performance, for the most neutral, accurate presentation, desktop to desktop, room to room. The cabinet’s precisely contoured low-frequency port works with the driver to provide accurate bass at all listening levels. And with low frequency extension down to 60 Hz, you’ll be impressed with the bass you get, even without a subwoofer.

Loud and Clear

JBL 104 Reference monitors offer this high level of performance, even at loud playback levels. This is accomplished through clean, integrated 60-watt Class D amplification that distributes 30 watts per speaker.

And with their efficient design, One Series speakers can be driven to 104db SPL (peak), without the distortion found in other monitors in their class.

Streamline Your Sessions

And JBL One Series reference monitors were created with the modern production lifestyle in mind. They not only feature a sleek, new look for JBL, but with their compact size, creators can get legendary JBL sound even in smaller workspaces. Smart features like a front-panel volume control

allows convenient level adjustments without straying from the sweet spot, the front-panel headphone jack automatically mutes the speakers, providing isolation in one simple step, and dual 1/4-inch balanced and single 1/8-inch unbalanced TRS inputs accommodate a wide range of sources.
