Stereo vs Soundbar

Your soundbar

Is lying

to you

Every uStream speaker works with WiiM, Amazon Alexa, and Google Home. Each platform does something different — and it's worth knowing which one is right for you.

The honest case
Two things your soundbar can't do.
Two things your soundbar can't do.

The soundbar industry is built on two assumptions: that you won't notice mono, and that you won't check what peak watts actually means. Both are wrong. Here is what the spec sheet should say.

Soundbar

One speaker.
One channel.

A soundbar is a single enclosure with multiple drivers pointed in different directions. It creates the impression of width through reflection and processing. It is not stereo. Music is mixed in two channels — left and right — and a soundbar collapses both into a single source. You are hearing a version of the music. Not the music.

uStream

Two speakers.
True stereo.

Every uStream speaker ships as a pair. Left and right connect wirelessly to each other the moment you power them on. No cable between them. No processing required to create stereo width — there is genuine physical separation between the two channels, because there are two separate speakers. The stereo field is real.

What is RMS — and why does it matter?

Via Bluetooth, each room operates independently — no multi-room sync. Connect your Nest device to a uStream speaker via 3.5mm aux cable instead and it joins Google's multi-room audio groups for synchronised playback. WiiM achieves the same wirelessly. No subscription required for smart home pairing.

Why it matters
Music is mixed in two channels.
Music is mixed in two channels.

Every album, every film soundtrack, every podcast produced in the last 60 years was mixed by an engineer sitting between two speakers. Here is what you lose when you play it back through one.

01

Instrument separation

In a stereo mix, the guitarist sits left, the vocalist centre, the keys right. In a soundbar, they all converge on a single point. You hear the music — but you lose the space it was recorded in.

02

Vocal clarity

Stereo separation reduces masking — the phenomenon where frequencies from different instruments cancel each other out. With true left and right channels, vocals sit in a clear centre image and never compete with the mix around them.

03

Depth and width

A stereo soundstage has a front, a back, a left edge, and a right edge. A soundbar creates a single horizontal smear. Width is simulated, not real. The depth dimension is lost entirely.

04

Film dialogue

On-screen dialogue is mixed to the centre channel. Stereo speakers reproduce this centre image accurately. A soundbar approximates it from a fixed position — which is why dialogue clarity drops when you are not sitting directly in front.

05

Dynamic range

Stereo amplification distributes the signal between two amplifiers. Each driver has its own headroom. A soundbar combines everything into a single amplifier chain — which compresses dynamics at high volume to prevent distortion.

06

Bass accuracy

Bass frequencies are omnidirectional — but bass content in a stereo mix is panned and mixed with spatial intent. A soundbar reproduces bass as a mono element. Stereo bass is more accurate, more controlled, and does not require a subwoofer to sound complete.

Common questions
The questions
worth asking.
The questions
worth asking.

Do I need to run a cable between the two uStream speakers?

My soundbar is rated at 300W. Why is a 100W uStream better?

Can I use uStream speakers with my TV?

Do I need a subwoofer?

Will they work with Alexa and Google Home?

What is WiiM and do I need one?

They are made in China. Does that affect quality?
