Can you post photos?

Hi Rashi

Many thanks for fast reply, greatly appreciated.

Both speakers are showing similar cracking just noticed them this morning doing household chores

Trust all my photos come out ok.

Cheers from beautiful Mauritius

Do you use your speakers outdoors? Are they exposed to extreme hot or cold temperatures or direct sunlight?

Hi Rashi

Speakers are in atmosphere controlled environment, humidifiers and a/c.  Normal temp 21 degrees humidifiers at 35%. Speakers not used out doors keep my "old play 5's" for that.

Cheers Allan 

Hi Rashi

Is it possible to purchase new play 1 cases? Before they start getting worse?

Allan

No, that isn’t possible. But you can get a discount on a new speaker through Sonos’ upgrade program: https://www.sonos.com/en-us/upgrade

Many thanks Rashi for your assistance, I shall look at the upgrade program but shipping to Mauritius is very expensive!!!

I shall live with the cracking until I can fly again.

Again my thanks.

Allan
