Overview
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.
