Tearing Down IKEA’S Sonos Speaker

There’s little better way to learn about a piece of electronics than by tearing it down. Taking a peek under the hood can reveal all manner of things about a device’s design, manufacturing, and origins. [This Does Not Compute] does a great job of doing just that, digging into the guts of IKEA’s Symfonisk speaker.

Symfonisk is a WiFi-enabled speaker, working with the Sonos ecosystem. Tearing down the device reveals some similarities to IKEA’s earlier Eneby speaker, with both devices sharing similar speaker drivers, apparently sourced from GGEC. However, upon digging deeper, it’s revealed that the Symfonisk has more in common with a speaker from another manufacturer entirely.

The video does a great job of not only investigating the manufacturing origins of the device, but breaking down the way it all works. This shows how the speaker relies on an Atheros WiFi-only chipset, thus explaining the lack of Bluetooth functionality, as well as discussing things like the neat solutions for cable management. Interestingly, the speaker uses a two-channel DAC and Class-D amplifier, but only operates in mono. Instead, the two channels are instead used to separately drive the tweeter and woofer, allowing EQ to be done in software on the main CPU, negating the need for analog crossover electronics.

It’s a teardown that would serve as a great primer for anyone considering building a piece of consumer electronics, but particularly those involved in the hi-fi space. To see how it was done way back when, perhaps try this 8-track teardown instead. Video after the break.

  1. “two channels are instead used to separately drive the tweeter and woofer”

    This is called “bi-amplification” in audio circles, just noting it here in case someone searches for that.

  2. Yes, overengineered, you would not design the electronic from scratch this way, but as it looks like a complete reuse, it’s the way to go.
    Pitty, no bluetooth, line in and always on (what’s the power?)

  3. I’m not sure if GGEC is supplying the whole loudspeaker set. When looking at the normal SONOS supply chain they are also getting their drivers from PSS (Premium Sound Solutions) and others.

    That said i’m not sure if this IKEA is just a watered down Sonos play one with the same drivers or they went the effort of designing something completely new just for IKEA.
