Sooo....much...rumble!
It actually gives me shivers sometimes when I'm watching well produced TV shows or movies.
At first I was slightly underwhelmed by it, but then I learned it was probably just a lot more subtle and less over the top then my old experience using a sub (a Logitech Z5500 hooked up to my PC for gaming)
Then I figured out how to tweak it and now adjust the levels depending on if I'm listening to TV or just audio, and found some great TV shows, movies and music that utilised the base frequencies well and it's amazing.
My Sonos journey started with getting a second hand soundbar for my TV, which was a fantastic step up from the built in speakers, I was even quite happy with moderate base at first, compared to the tinny flat screen speakers.
Then I saved up and forked out for 2 x Play 1s when my local hi-fi shop had them at 10% off, so I could place one either side of the sofa for surround sound.
Great upgrade, makes a big difference to TV viewing and helps you to appreciate the background audio more.
After that I said screw it, and bought another Play 1 for the kitchen, which is nice as it means I can keep the volume at a reasonable level in the lounge and kitchen instead of blasting the lounge to hear it in the kitchen.
Finally a few months later I pulled the trigger on the Sub. I still think it's ridiculous how much it cost, but treated myself for my birthday, so glad I got it.
I'll tell you the feature that led me to get the Playbar to begin with - is the Quiet mode where it will stop the volume from peaking too loud if it fluctuates a lot. I wanted this so I didn't disturb my housemates when watching TV. There's also Voice Enhancement now too, those combined mean I'm much more comfortable watching TV late at night without worrying about disturbing my housemates.
When they're away however, with the sub I can now make the entire house shake. I'd be wary of buying one it I was in a flat or semi-detatched. Even in a detatched house, it sometimes makes me think "Bloody hell, I hope the neighbors can't hear this", but it makes TV and Movies so much immersive, it's so good
With regards to sub positioning, initially I was worried about where to put it, as my lounge area is pretty tiny, in the end I put it on the other side of the room under a side console where it was a bit more open, instead of trying to jam it into a small space next to the sofa or TV, and the sound travels great.
I do wish there was a way for me to connect my desktop to it over the network though. At the moment I've got some £15 logitech speakers on my desk in the same room, which seems a bit silly.
The windows app is good for controlling streaming music direct to the system, you just can't pipe in music from the computer the app is running on, which is a bit frustrating.
I also wish there some some kind of continuity feature or Apple Podcast app integration, so when I arrive home listening to a podcast, I could hand it off to the Sonos system and have it pick up where I'm playing. Not sure if there's a way to do that.
