The JBL Professional 104-BT is a 2-pack of compact, powered 2-way reference monitors designed to deliver the truest, most accurate sound reproduction in their class. Drawing from over seven decades of JBL's engineering expertise, these monitors combine a 4.5-inch low-frequency driver and a .75-inch soft-dome high-frequency driver with powerful 60-watt amplification to provide outstanding fidelity and detail. Ideal for home recording enthusiasts, podcasters, video producers, and professionals looking for accurate, portable reference monitors, the JBL 104-BT offers exceptional imaging and a neutral frequency response. These monitors are specifically designed to offer an incredible balance between compact form factor and superior sound performance, making them perfect for environments where desk space is limited but high-quality sound is required.

Featuring Bluetooth 5.0 streaming, the JBL 104-BT allows you to reference mixes directly over Bluetooth, in addition to a range of wired input options including 1/8" Aux, RCA, and 1/4" TRS balanced inputs. With its sleek matte black finish, molded ABS cabinet, and contoured low-frequency port, the 104-BT blends seamlessly into any workspace while providing optimal bass response. The monitors are acoustically optimized for desktop placement, ensuring accurate sound reproduction even in crowded environments. The front-panel volume control allows for easy level adjustments without leaving the sweet spot, while the front-panel headphone jack offers a convenient way to isolate the sound by automatically muting the speakers. With a maximum continuous SPL of 92 dB and a peak SPL of 102 dB, the JBL 104-BT delivers clear and detailed audio, whether you're mixing music, editing video, or listening to your favorite tracks.

The JBL 104-BT's design also includes smart features like the ability to control input selection directly from the front panel, allowing you to toggle between Bluetooth, Aux, RCA, and TRS inputs or combine them for maximum flexibility. The host monitor includes electronics for the extension monitor, minimizing wiring and clutter in your workspace. Additionally, the low-profile design and compact size of the 104-BT make it a perfect fit for small studios, desktops, or any setting where premium sound and space conservation are priorities.
