capacitor durability in home theater product

I was watching a tear down on the Ikea sono compatible speaker and the person doing the tear down notice that Ikea cut corners on capacitors and that they may need replacing in a couple of years. I was wondering if this is true or not. Do we have to worry about caps failing on our electronic products?

Depends on the actual rating of the capacitors. Good thing that in speakers they dont get that hot, but bad thing is that audio devices are more sensitive to degraded capacitors (even if they still somewhat work).

Can you link to the teardown? Hard to make any conclusion until we actually see what kind of capacitor they are using.

The teardown is at this youtube video: Discussion of capacitor at 5:25. The picture shows the brand as CapXon (what does regular sonos one use, I wonder?)

I google CapXon and apparently there are  lot of links to failure due to cutting corners. However, I notice in the teardown of Sonos Play 1 that they also use CapXon caps and Sono Play 1 have been around for a while. At the very least, there's no reason to not use the Ikea speakers due to the cap since Sono Play 1 and probably the Sonos One use the same caps.
