Dumpster teardown of a Sonos Play 5 Gen 1 Wifi speaker system.
Is this the Juicero of wifi speakers? or is it just a really well designed active speaker?

    Useless glue on bottom of PCB could be for resonance, just some dead weight

  2. Avataaar/Circle Created with python_avatars popraw a says:

    Industrial solutions, but in ABS enclosure

  3. Avataaar/Circle Created with python_avatars DJ_PaulTUK says:

    Yes to have to register these things to get them to work. There is a button sequence to factory reset the device, which i cannot remember.

  4. Avataaar/Circle Created with python_avatars Jasper Waale says:

    will explain why cost so much

    I have a bunch of Sonos speakers. Would I recommend them? Not really – their control software is *horrible*. Really wish they had a browser based configuration like my old Sony sets had. But, they work fine as Airplay devices and are cheaper than many of the alternatives. Also, why the heck does the Connect (or whatever it's called these days) cost so much!

  6. Avataaar/Circle Created with python_avatars Johnson Lam says:

    Very "audiophile" feel since they seriously treated vibration during music output, and lot of damping material.

  7. Avataaar/Circle Created with python_avatars RedwoodRhiadra says:

    Unlike the Juicero, this has a function you can't do with your bare hands…

  8. Avataaar/Circle Created with python_avatars PushyPawn says:

    I've never heard anyone in OZ refer to silicone as silastic(?), and I'm a tradie.
    Maybe it's a boomer habit like calling a pen a Biro or a vacuum cleaner a Hoover.
    Could be a linguistic difference between states too.

  9. Avataaar/Circle Created with python_avatars erroltheterrible says:

    Hmmm, great hack potential. Just connect a Pi to the DAC…

  10. Avataaar/Circle Created with python_avatars infango says:

    venture capital i drying out people are throwing away "broken" hardware

  11. Avataaar/Circle Created with python_avatars Pete Mundy says:

    So is it correct to say that this audio amplifier design was a 'class B' design?

  12. Avataaar/Circle Created with python_avatars steaker1705 says:

    I’ve owned taken apart a Gen. 2 and they simplified it a bit, but it’s mostly the same well built as this machine. Sadly the WiFi in those machines are known to die.
    I currently own a Gen. 3 (renamed slightly) and it’s absolutely worth every penny.

  13. Avataaar/Circle Created with python_avatars Pete Brown says:

    I have a Gen 1. Yes, they work, but you do need to go through and set up an account, IIRC. It sounds pretty decent. I use it in my shed workshop.

    But it's not like a phone BLE speaker. It has its own connection and it's not streamed from your phone.

    All the silastic makes sense for something that is going to vibrate with bass.

  14. Avataaar/Circle Created with python_avatars Elwood Cope says:

    Sagan is making me feel old.

  15. Avataaar/Circle Created with python_avatars Stephen Tidwell says:

    I know a guy with a large number of these in his house. Pair with the subwoofer it has amazing sound and volume levels. Can’t say I like the app experience though. I’m not surprised it wants your information to get an update 😂

  16. Avataaar/Circle Created with python_avatars Picobyte says:

    The Devialet speakers beat that on all fronts.
    Got two phantoms here, they are super heavy, have excellent bass down to 16Hz for earthquake effects.

  17. Avataaar/Circle Created with python_avatars blargg says:

    Apparently your request to the universe to find a speaker for Sagan hasn't been closed so it's still causing them to pop up.

  18. Avataaar/Circle Created with python_avatars Grey Hodge says:

    It’s a luxury product, not mass market.

  19. Avataaar/Circle Created with python_avatars DashCamAndy says:

    My goodness, seeing Sagan was a shock! As we used to say in the US, "growing like a weed."
    I'm seriously considering moving, at least temporarily, to Australia just to nicely-furnish a home from Dave's work dumpster!
    You'll know me when I get there, I'll be the only one driving a Camry sensibly (and it'll be left-hand drive, I'll ship mine out just to confuse everybody). 😆
    I'm pleasantly-surprised at the build quality of this unit. It seems to be built with attention-to-detail. Customized bass ports, each driver acoustically isolated, obsessive effort taken to mitigate PCB vibration, every single wire foam-wrapped, plenty of mounting screws from several sides (case vibration), the WiFi antennas… A fair bit of the MSRP was obviously in the engineering.

  20. Avataaar/Circle Created with python_avatars DeDeNoM says:

    I think I remember a former Sonos engineer on the Amp hour. Maybe he can tell who designed this.
