Product Overview & Specifications
The WiiM Sub Pro is a high-performance active subwoofer designed to deliver tight, clean low-frequency extension down to 25 Hz. Housed in a vibration-resistant minimalist chassis, it pairs a custom 8-inch driver with a 250W Class D amplifier capable of reaching 104 dB SPL. Engineered for seamless integration into both WiiM streaming ecosystems and third-party audio systems, the Sub Pro features ultra-low-latency Wi-Fi 6, Bluetooth 5.3 with LE Audio, Gigabit Ethernet, and a universal RCA sub input.
Driven by AI-powered RoomFit™ auto-calibration, the Sub Pro automatically analyzes room acoustics and speaker placement to optimize bass response. Deep personal customization is accessible via the WiiM Home App, which offers full control over crossover, phase, level, latency, and a 10-band parametric EQ (PEQ) alongside automated power management and over-the-air firmware updates.
