Sonos Gen 3 sub blown after 2 years of light use

I have 2 Sonos Gen 3 subs, one works great, the other developed a rattle with low bass and is blown (sounds like a fart) (which I didn’t think could happen, didn’t have the sub volume up too much, just at (+3). 

Called CS and after tweaking and updating, they agreed it’s defective. The problem is the only solution is to send it back and buy a new one with a 30% discount (but the subs cost $799). So my sub lasted 2 years without any abuse. That is disappointing. Should I buy another sub or is this common?

    UPDATE: Sonos heard my exemption plea as my blown sub was as it turns out when I researched when I bought it, just 14 months old and have agreed to send me a replacement. So all is well that ends well. 👍

    Yes Mother Nature is never fair. Specifically with SUB, a small child or critter can introduce a foreign object through the SUB’s ports.

      You can get or make a speaker cloth cover for the Sub, or several folks sell grills to go over the openings and prevent things from getting inside.

      If you have kids, critters or big bugs I’d recommend using one of the above.

        Received my replacement Gen 3 sub today and integrated it into the system (An Arc and another sub) and after a little tweaking with the settings (at first it wasn’t recognizing the additional sub) it is now added. Nice to have 2 subs once again.

        I use this system for tv viewing and the subs don’t really have much to do with normal programming, you really only hear the subs get some boom when a commercial comes on. That’s why I was surprised that one of my subs had a blown speaker. 
         

        Sub setting right now is +7. What is the max that is considered safe for these subs? I know they go to +15 but I’m not going that high.

        Glad you are getting (or have received ) your replacement sub. I’m a bit curios as to why you find it necessary to have the sub EQ @ +7; based upon your use case. I have dual subs in a 20 x 18 x 8 room and sub EQ is neutral after TruePlay tuning (see diagram below). 

        There are four  (4) possibilities that may have led you to set the sub EQ @ +7:

        1. You have a much larger room and/or open space
        2. You’re not able to use TruePlay.
        3. You haven’t experimented with sub placement options 
        4. You just prefer a boomier sound

        If you would please let us (Me) know your reasoning: 😊

          I have a really large room 35 X 20 so the two subs which are by the tv at one end of the room (one behind the stand on the left and the other out towards the wall/ corner on the right), similar to your diagram. So the boost to +7 seems to work but it iwas adjusting the phase from 0 to 180 seems to have really helped the most.

          Got some nice bass response today while watching The Accountant from Amazon Prime. Not boomy at all.

          This system is primarily for movies/tv so a little extra boom is good. Music of course benefits from tighter bass.
