Unfortunately, as I've found, you have three options.
1) Put up with it (even after moving the sub to another location)
It's shocking how it's not been updated, but clearly it's a hardware issue, not software. Pretty poor product testing if I am being honest.
No doubt this will be sorted when they announce a new sound bar, which includes Atmos - which we'll no doubt need to by a whole new setup, rather than replacing the sound bar itself.
add me to the bunch!! i just had this setup for less than a week, two nights ago the Sub start to "pop" randomly, i have a Cisco Meraki MR33 AP, and it is a very powerfull AP with a broad broadcast spectrum, for some odd reason Bose Soundtouch will not connect to it eventhough it's only 5 feet off the ceiling, when i managed to connect to it the signal was "Fair", i disconnect and connected to ATT (1Gb/s) router which is upstairs 20 feet away, and the signal is "Excellent", Im a network engineer and i know a bit about networks, my home network is in mesh and there is no reason for the Bose not to connect to it, it turns out this stupid thing will interfere with 2.4Ghz band, so if you want the pop to stop, you need to manually disabled the chanell from broadcasting, my issue is i have smart thermostat thant needs the 2.4Ghz band, so im not going to change how my network configuration so Bose can operate, it should be the other way around. anyway im returning this product, for $1400 system this should not be happening.

Sonos does not support DTS, you might need to think about that since DTS is the widley used audio format for all DVDs and blueray players. i disconnect the wifi on my soundtouch and teh Sub is linked with no issues to the soundtouch and there is no poping noise at all.

Following the advice of one of the posters here, I configured all my wireless routers’ 5GHz wifi signals to channel 48. After doing this, I’ve had no more popping sounds.
Do try it out and see if this can help you guys... Cheers

Thanks for posting and all the detailed information. I just wanted to jump in here and mention that the current Acoustimass base modules will be compatible with the Soundbar 500 and 700.
