Wiim Sub Pro Hi-Fi Subwoofer White

WiiM Sub Pro — Active Wireless Subwoofer with 250 W Class-D Power

The WiiM Sub Pro is a smart active subwoofer designed to anchor the low end of any modern hi-fi, stereo or 2.1 home-theatre system. Built around a custom 8" long-throw driver and a built-in 250 W Class-D amplifier, it delivers distortion-free bass that reaches down to 25 Hz (-10 dB) and stays musical up to 200 Hz. The WiiM Sub Pro is the right choice for listeners who want cinematic depth and tuneful bass without running a cable from their amp to the sub.

What Sets the WiiM Sub Pro Apart

Most wireless subwoofers lock you into one brand's ecosystem. The WiiM Sub Pro breaks that rule by combining Wi-Fi 6 and Bluetooth 5.3 LE wireless pairing with a universal RCA sub input, so it works just as happily with a WiiM Amp Ultra as with any third-party receiver that has a subwoofer output. AI-driven RoomFit™ auto-calibration uses your phone's microphone to analyse the room and tune the sub in place, while the WiiM Home App exposes a 10-band parametric EQ plus adjustable crossover, phase, level and latency for hands-on fine-tuning.

Driver and Amplification — The Heart of the Sub

The driver and amplifier pairing is what determines whether a subwoofer shakes the room or just thumps. A custom 8" woofer with 104 dB SPL sensitivity moves enough air to fill medium and large rooms, while the built-in Class-D amplifier delivers 250 W of RMS continuous power with high efficiency and low heat. The result is tight, controlled bass that holds its composure at high listening levels.

• Driver: 8" custom long-throw woofer — high-excursion cone for clean output at low frequencies
• Sensitivity: 104 dB SPL — strong output for the amplifier's power, ideal for medium-to-large rooms
• Built-in Amplifier: 250 W Class-D, RMS continuous — active design, no external amp needed

Frequency Response and Tuning — Reaching the Deepest Notes

A subwoofer's value is measured in how low and how cleanly it plays. The WiiM Sub Pro is rated at 35 Hz – 200 Hz (±3 dB) with usable extension down to 25 Hz (-10 dB), covering the sub-bass region that gives movies and music their physical impact. RoomFit™ calibration, the 10-band parametric EQ and adjustable crossover let you blend the sub seamlessly with bookshelf or floorstanding speakers.

• Frequency Response: 25 Hz – 200 Hz — full-range sub-bass coverage for music, film and games
• Calibration: RoomFit™ AI auto-calibration — adapts bass output to your room's acoustics
• App Control: 10-band parametric EQ, crossover, phase, level and latency — full manual tuning via the WiiM Home App

Connectivity and Placement — Wireless or Wired, Anywhere

True wireless flexibility is the headline feature. Wi-Fi 6 delivers ultra-low-latency streaming to compatible WiiM streamers, amps and speakers, while Bluetooth 5.3 LE adds flexible pairing with supported devices. An Ethernet port serves wired networks that demand zero compromise, and the RCA Mono In accepts any third-party subwoofer output. The vibration-resistant chassis houses the electronics in a minimalist cabinet sized at 399 × 301 × 322 mm and weighing 16 kg.

• Wireless Inputs: Wi-Fi 6, Bluetooth 5.3 LE — cable-free pairing with WiiM ecosystem devices
• Wired Inputs: RCA Mono In, Ethernet — universal compatibility with any receiver or amp
• Dimensions: 399 × 301 × 322 mm — compact cabinet that fits beside a TV stand or in a corner

Who the WiiM Sub Pro Is For

The WiiM Sub Pro is the right choice for hi-fi listeners and home-cinema fans who already own a WiiM streamer, amplifier or speaker and want to add deep, room-tuned bass without running a long subwoofer cable. It is equally suited to owners of any third-party amp or AV receiver with an RCA sub output who want a smart, app-controlled sub that can be tuned from a phone. Music lovers running bookshelf speakers, movie fans chasing cinematic rumble and gamers wanting tactile low-frequency impact will all benefit from the 8" driver, 250 W Class-D power and AI-driven RoomFit™ calibration.

WiiM — Smart Hi-Fi for the Connected Home

WiiM, a brand by Linkplay Technology, has built its reputation on streaming amplifiers, streamers and smart speakers that pair audiophile-grade hardware with one of the most polished control apps in the industry. The WiiM Sub Pro extends that philosophy into the low frequencies, adding a wireless, AI-calibrated subwoofer that integrates with the wider WiiM ecosystem and with any third-party system via RCA. Regular over-the-air firmware updates keep the platform evolving long after purchase.
