Hacking the Sonos Ikea Symfonisk Into a High Quality Speaker Amp

Could it be an idea to instead of ripping out the interior and connecting it to a speaker, build a new better enclosure in wood instead? In the process you could change the woofer and tweeter. Tried to find if anyone tried it out but haven't found anyone who have done it.. yet at least :)

I don't know how you're going to get a better enclosure without ripping out the existing interior. Are you thinking you'd just pull out the woofer and tweeter, and then connect the speaker wires to a new box with new woofer & tweeter that also hold the entire old box?

If you're going to use a different woofer and tweeter, why not just open up an existing passive speaker, put the amp inside that box, wire it, remove the existing speaker posts and use that hole for the power cord?

my integration of symfonisk motherboard in jmlab 706s speaker (based on makezine.com).

Notes :
- need to extend internal AC wire (be careful) and internal speaker wires.
- trueplay makes miracle (on/off it changes everything).
- don't forget to disable loudness (to heavy to drive for the digital amp at high level).
- enable volume limiter to 85% (to heavy to drive for the digital amp at high level).
- i don't bypass the speaker crossover for the moment

Cool! Looks like what I was thinking would work well. Assuming you just used an existing passive speaker instead of building your own box.

These are nice hacks… basically swapping out the output devices.

I've been thinking about input to the Symphonisk though.

I'm curious how a pair syncs sound.
If it's not that both are streaming the source, playing one channel and exchanging sync info, it might be there's a protocol where one is streaming and resending other channel to the other device.

If that's the case, then what if another device (e.g. a PC/Pi) were to pretend to be either and send a stream to each; so effectively become a Connect without the hardware inputs?
Has anyone tried to play with the software side?

In a pair, one (usually the left) fetches the stream and sends it to the other. Each applies a channel map. The units exchange timing information to maintain sync.

Playing with the software side? The notion of a 'software ZonePlayer' has been doing the rounds since 2005. It would imply the implosion of Sonos' business model. Everything is locked down tight.

I looked at doing something Sonos like using Raspberry Pi computers and digital i/o or amplifier HATs and it doesn't look unreasonably hard.

What is a problem are the software patents ratty mentions. Trying to find a way around them would require a lot of legal fees as well as input from technical experts. The risk in ignoring the patents and just quietly building a personal system is low UNLESS it leaks to the public and the lawyers come calling. I'm not that brave so I did something else less risky.

Teardown reveals that the Symfonisk uses the exact same Sonos electronics board as the Play:1. Amplifier chip is the well-regarded Texas Instruments TPA-3116, which can deliver up to 50 Wpc at 24V.

It is interesting the Ikea speakers get airplay 2 but the Play1 doesn't. I thought the Play1 didn't have the capability full stop. What am I missing?

As he surmises in the video, Sonos switched to a newer CPU a couple years ago that is capable of AirPlay, but probably didn’t want to confuse/piss off owners of the older Play:1s by adding AirPlay to the newer generation. The SL, which replaces the Play:1, is fully AirPlay enabled. I wonder if it will have the same board inside?
