Patented ®ISP™ Coaxial

Precision Sound Since 1994

MiniMax3 features SOVOX’s exclusive ISP™ coaxial technology, refined since 1994, delivering phase-accurate sound and clear imaging for reliable nearfield monitoring.

Active–Passive Dual Bass System

Clean Low Frequencies Down to 45kHz

MiniMax3 pairs an in-house designed 3.5-inch active woofer with a 5-inch passive radiator, delivering deep, controlled bass with low distortion—solving the limited bass extension of traditional 3-inch monitors.

Why Three-Way Sounds Different

MiniMax3 rethinks compact monitoring with a true three-way design in a 3-inch format.

Unlike conventional two-way designs, its three-way architecture separates low, mid, and high frequencies across dedicated drivers, resulting in cleaner mids, smoother transitions, and a more balanced, consistent sound—clearly reflected in the measured frequency response.

DSP Room Adaption

MiniMax3 offers four placement presets—Free Field, Desktop, Near Wall, and Desktop Corner—to compensate for boundary effects and placement-related tonal changes.

Combined with manual HF and LF adjustment, it ensures clear, balanced nearfield monitoring in any space, even small rooms.
