I did the same hack, except using two Symfonisk's and just connecting the existing speaker lines to a pair of floorstanding two-way speakers (Kef iQ70 from the 2010's).

The little amp in the Symfonisk is plenty powerful to drive these large speakers. The crossover is completely off by default, but by using Trueplay the crossover gets tuned properly and the sound is pretty damn good (albeit a tad boosted in the highs).

It's a great way to get super convenient (Airplay 2) and high quality sound in a room, just with a power cord for each speaker. And these quality Hi-Fi speakers are readily available for cheap second-hand... some pics here: https://twitter.com/jstsch/status/1529204823912075264/photo/...

Could you expand on this? What do you mean by the "existing speaker lines"?

Instead of modding it into a new amp like this post does they likely just spliced the speaker wires right into the speakers. The upside is it was easy the downside is you can’t just plug and play after the fact.

Indeed! Nice thing is that two Symfonisk's give you great stereo sound on external speakers. And no soldering inside the Symfonisk, just some connectors to unplug and run the cable out of the bass reflex port, so easy to restore in original condition if you'd want to. So thanks to the magic of these tiny transistor digital amplifiers, in total you'll spend ± 500 euros and have better — and super convenient — sound than quite expensively priced systems.

So if you open up the Symfonisk, you'll find that the cables running up to the tiny tweeter and woofer speakers have a nice flat crimp connector on them.

So simply unplug those (carefully, use tweezers to squeeze the connectors and they'll pop off without friction), and connect those on some cables which you'll run to your speakers. The connectors can be found at your local electronics store.

The speakers you'll be connecting need to have a crossover that you can bypass (typically four connectors on the back versus two, with a piece of metal in between to short them). Total upgrade would be to mount all the electronics inside, but I haven't dared to cut mine open yet
