How to turn $99 Ikea Sonos into speaker amp

Really cool article.

quote:

Plug in the AC cord, launch the Sonos app, and launch the real star of the show, the TruePlay tuning feature baked into the app, and your board. Follow the directions, disregarding that your speaker isn’t in its final resting place, as you can simply retune it later. The TruePlay software quickly adapts the digital crossover within the board, allocating the correct frequency ranges to the woofer and the tweeter of your speaker, making it sound near perfect


quote:

And there you have it! One half of the perfect budget Sonos system. Repeat the procedure for your second speaker, maybe build yourself a nice enclosure for the electronics, and relish in the glory of a beautiful pair of Airplay-2, Sonos-enabled, TruePlay-tuned speakers for a few hundred bucks.

Seems like a lot of work when you could just buy a chrome cast audio and outlaw wireless audio kit for the same price.

Are you going to try this out? May have to look for some marketplace speakers that match the configuration.

Your title cracks me up. Great to start the weekend with a nice laugh.

Let me know how that discontinued Chromecast that doesn't include airplay 2, trueplay or the Sonos ecosystem works out for you in a year.

This is a cool reverse engineering hack that demonstrates what can be done and nothing all that complicated about taking the speaker apart if you follow the steps.

There are numerous options to turn a receiver smart if it’s not already. A regular chromecast does the same thing and let’s you mirror whatever you want from your phone. It let’s you stream whatever you want. If you want the Sonos ecosystem, then buy Sonos speakers. Paying $100 per speaker to get old bookshelves with exposed electronics to be “Sonos” speakers when there are other easier wireless options just seems pointless.

That is pretty cool. How does the Trueplay DSP work? Is there a microphone involved?

I believe the app uses the mic on your phone.

Best Buy has them back on display. Still my favorite music purchase ever.

Which is exactly why I'd never push them from a powered speaker's internal amp that was disconnected and hideously reconfigured.


If you like the Sonos ecosystem so much, may I ask what's wrong with the $600 amp or previous gen amp for around $450?
Or, for that matter, a $350 Sonos Connect with the amp already connected to the bookshelf speaker?



There are so many options that just seem so much more stable for not-that-much more...?

amazing.



guy reverse-engineers a cheap ikea/sonos speaker to show it has lots of potential and all you focus on is 'oh the exposed circuitboard is hideous'

is that what you got from this article?

Reverse-engineered? I think not. The guy took apart a $100 speaker and hooked the insides to another speaker.


Again, to get a pair of speakers connected, you're paying $200 for a far lower quality amp and presentation than buying the amp itself.



I'm just missing the exciting part about this. Would you expect the amp to be tied to the speaker in some way that is locked down? Outside of a few 2.1 computer speakers and a certain Bose system, I've never seen an amp that you couldn't find a compatible speaker for. I don't understand the idea of pairing a truly pedestrian (at best) amp with a pair of truly high end speakers.

Let's just say you found the speakers in a thrift shop for nothing and wanted an amp for them. Is $200 + hassle that much easier than $350 for a Sonos Connect and any old stereo receiver from the same thrift store? Is there really a market that wants Sonos connectivity that is winning to pay $200 that won't even consider a $350 splurge? I'm being quite serious here. And I'm quite thrifty and DIY. I just don't see the benefit when you're voiding the warranty to get a discount.

^^^^^ all of that.


It’s cool if you did this just tinkering around with some crap you got laying around. But in no way would this be a reasonable option for your home audio build. I could totally see wanting to use the old speakers too but taking apart two speakers from IKEA to power them is comical. Just like the title of this thread.

I’d laugh at it just like I did this thread. You got a link?

Wouldn't it be less expensive to just use the DSP features in your amp?
