JBL 104SET-BT-US JBL 104 Studio Monitors B-Stock
The JBL 104 pair delivers compact, articulate monitoring in a footprint that fits tight spaces without sacrificing acoustic accuracy. These coaxial-driver monitors excel at revealing mix details across a variety of genres and production styles, making them a dependable choice for sound engineers, performers tracking their own material, and anyone running live mixing or rehearsal monitoring setups in small to medium rooms.
Design & Build
The coaxial driver architecture aligns the 0.75-inch soft-dome tweeter with a contoured 4.5-inch woofer cone, creating superior phase coherence and a focused stereo image from a variety of listening positions. The 1st-order crossover at 1725 Hz ensures smooth integration between drivers, while the compact enclosure minimizes room interaction and setup complexity—critical for portable rigs and venues where space is limited.
Audio Performance & Connectivity
60 watts of integrated Class D amplification (30 watts per speaker) delivers controlled, low-distortion output with 87 dB SPL sensitivity at 1 meter. Multiple input options—Bluetooth 5.0, RCA, TRS, and auxiliary—provide flexibility for connecting to audio interfaces, live-sound controllers, computers, and mobile devices without additional adapters or external amps, letting you set up fast and run reliable for rehearsals, small venues, or monitor mixing duties.
