Thanks for the post, and I'm sorry to hear about the difficulties you're having with your Cinemate system.
Just to confirm - only the bass is dropping, and only when playing PS4?
Is your PS4 connected to the internet using Wi-Fi or Ethernet? The wireless acoustimass module uses similar frequencies to your home router in order to communicate with the Cinemate console, so the Playstation may be interfering with those signals. Moving the PS4 or using ethernet for internet may help.
Let me know so we can get this resolved for you.

Thanks for the update. The Cinemate 120 would use an SMB cable to connect the wireless bass module to the console. I would recommend contacting your local support center to see if they can send you one to see if it helps resolve the bass drop outs. Just click HERE and select your country and Contact Us at the bottom of the page.
Also, has this been the case with the PS4 since owning system, or did this issue start up recently? Was there any new wireless devices introduced to the ecosystem?
Let us know so we can further assist!
