JBL Pro JBL 104 (Pair) 4.5" Studio Reference Monitors

Transparent and Powerful Sound

JBL employ cutting-edge technology and components to achieve optimal clarity and transparency. The combination of the 4.5-inch Coaxial LF driver and the .75-inch soft-dome HF driver results in an ultra-wide frequency range, with no colouration. The result is exceptional audio fidelity, capturing the subtle nuances from your source audio, whether it be video or music.

The 104 Reference Monitors have been optimised for desktop placement. Conventional monitors can incur unwanted resonance when placed on desks or wooden surfaces. The unique design combats this ensuring a natural low-frequency performance. It also boasts a smooth-off-axis response so capturing the sweet spot is easier than ever.

Ideal For Music, Gaming and Video Production

Some of the world’s most revered artists and recording studios use JBL loudspeakers and monitors, thanks to their high-end audio performance and reliability. JBL have used the same technology within the One series of monitors. One of the most prominent examples is the new coaxial driver design.

The monitors provide high-levels of performance and playback volume. At the heart of the monitors is a 60-watt Class-D power amplifier, distributing 30 watts per speaker for optimal efficiency. The speaker can be driven up to 104db SPL (peak) without distortion, making it one of the best monitors in its class for sound levels.

The powerful sound and portable size makes them perfect for a range of applications. From music and video production to online gaming. The immersive and powerful sound will put you at the forefront of your audio.
