WiiM Sub Pro Wireless Subwoofer, White (Each)

The WiiM Sub Pro is an active subwoofer with an 8-inch driver that joins your system wirelessly over the network or the classic way, via RCA. In White, it's the variant for bright rooms where a black box would otherwise stick out like a sore thumb.

Why the WiiM Sub Pro?

Because it solves the cable problem. A subwoofer rarely sits where a power outlet and an RCA cable happen to meet. The Sub Pro connects directly to your WiiM device over Wi-Fi 6E, with very low latency and without a cable running across the living room. If you'd rather wire it up, use the RCA input – then it works with any system that has a subwoofer output.

Fine-tuning happens entirely in the WiiM Home app: crossover frequency, phase, delay, level, and a 10-band equalizer. No guesswork twiddling dials on the back while someone on the sofa shouts "more" or "less".

What you'll hear

A 250 W Class D amplifier drives the 8-inch long-throw driver in a bass-reflex enclosure down to 25 Hz. The result isn't an intrusive boom, but what a compact speaker is physically missing: the foundation under double bass, kick drum, and film soundtracks.

RoomFit calibration measures your room through the paired WiiM device and smooths out the worst peaks. Especially in living rooms with lots of glass and little soft furnishing, that's the difference between "bass" and "mush".

Who is the WiiM Sub Pro for?

For anyone with a WiiM Ultra, Amp Pro, Amp Ultra, Sound, or Sound Lite who wants to turn a small system into a full-fledged one. And for anyone looking for a wireless subwoofer who doesn't want to be locked into a closed system – via RCA it fits any setup with a sub output.

Plain talk: The Sub Pro doesn't work wirelessly with the WiiM VibeLink Amp – that amplifier has neither a network connection nor a subwoofer output. And at 16 kilograms and nearly 40 centimeters wide, the Sub Pro isn't a piece of furniture you just shuffle around. Measure up beforehand where it should stand; subwoofers are sensitive to placement.

Our verdict

The Sub Pro is the most sensible upgrade a WiiM system can get. It turns two compact speakers into a system that doesn't flinch at movie night, and the app-based calibration spares you the usual fiddling. In White, it disappears into bright rooms with surprising discretion – which, for a device this size, is quite an argument.

Frequently asked questions

Which devices does the WiiM Sub Pro work with wirelessly?

Wirelessly, it works together with the WiiM network devices: Ultra, Amp Pro, Amp Ultra, Sound, Sound Lite, and the WiiM Bar. That's not possible with the VibeLink Amp, which has neither a network connection nor a subwoofer output. Via the RCA input, it runs with any system that has a sub output.

Can I also run the Sub Pro with a non-WiiM system?

Yes. The RCA input accepts the signal from any amplifier or AV receiver with a subwoofer output. However, RoomFit calibration and the app-based fine-tuning are then only available to a limited extent, since they run through a paired WiiM device.

Where in the room should I place the subwoofer?

Usually near the front speakers, but not exactly in a corner – there, the room boosts the bass too much. A distance of 20 to 50 centimeters from the wall is a good starting point. Then run the calibration. If you'd like, we'll go through the placement together – that often achieves more than pricier gear.

Why buy the WiiM Sub Pro at HD Zürisee?

Because a subwoofer is the component where room and placement matter more than the spec sheet. That's exactly where our experience counts most. Our technician Maurizio delivers and calibrates it on site if you'd like – at 16 kilograms, an offer people are happy to take us up on.
