Now Playing Trueplay - Your Impressions

Further to the above, I went back to see if I have missed something subtle in Trueplay in a duet album of Houston Person and Ron Carter. I toggled Trueplay, but I did not hear anything different from either. Toggling the Sub on the other hand makes a subtle but very palpable difference in how present Carter's voice is in the room because of the Sub.

I bought 'Just Between Friends' because of you. Thanks for that. Awesome late night living room listening treat right there.

:-)enjoy. The other three are just as good. Carter keeps the albums from sounding just more of the same, as Person albums tend to.

I noticed that with Houston Person, whom I also 'discovered' because of you.

Where the difference is profound, are you able to see that on the usual freq response graphs and if so, how does it show up there?

I am going to take another stab at my living room in the way you suggest - as opposed to the video instruction of largely picking up wall reflected sound all around the room, from relatively close to the walls.

Perhaps that will result in something audible, but I now will not be surprised if it doesn't.

Sorry, in this case I did not attempt to measure anything, but the overall balance had obviously been rearranged. In many "before" and "after" comparisons, one must flip back and forth several times in order to discover a very subtle change. In this case the change was almost startling. Similar to flipping a couple bands on a graphic equalizer from neutral to full. In earlier location (the one that I measured), one could flip back and forth many times and not be sure that there was a difference.

Most room response DSPs I know deal with bass bloat from room nodes and smoothen out consequent bass peaks - which allows for a better mid range performance. In the few charts I have seen of post Trueplay measurements I haven't seen any smoothening of peaks, just a shelving roll off for the low frequencies. I am not sure what other tricks Sonos has been able to do via DSP that are unique and unprecedented and Sonos isn't saying.
Yes actually, in my experience it does smooth out the peaks and it also throws more mid/upper-mid to the PLAY:1's and lets the SUB do mostly lows, in saying that the SUB does still play the mids just at a more subtle rate to the point where I can't notice until I am near it very close, this just makes it (in my opinion) perfectly blended with the PLAY:1's. I like it!

Single Play:1 in kitchen, lousy location on breadbox, up against back wall, under cupboard, boomy bass. After tuning, huge improvement, tight bass, much cleaner vocals.

Play:1 pair on desk in tiny office, nearfield, tuning didn't do much, as they already sounded fantastic.

No SONOS controller for my Lumia so I borrowed an iPAD and went for a wave

Play 1 in study - no appreciable difference
Playbar, sub, two play 3s in lounge - trueplay not available
Two play 5s in dining room - no appreciable difference
Play 5 in gym - no appreciable difference

In all cases SONOS app reported only subtle changes made

I think that the test noise was loud enough to scare the neighbours though

Given the ecstatic reviews above perhaps I may try turning Trueplay on and off and experimenting with different music

Maybe try tuning the study again. That single play one would normally tune to a big difference unless a perfect room.

So I tuned 3 rooms after upgrading to the version 6 controller software. In they case of each room, the differences were subtle - but noticeable.

All I can say is that after tuning the music sounds ---- well more musical! The vocals are more pronounced and the bass is more taught and with more punch. My wife noticed that the music sounded better but could not put into words. "That sounds really good"

I would look at it this way: all speakers interact with the rooms they are placed in. Manufacturers have no way of knowing where or how the speakers will be placed in a room and the volume of the room. Some rooms are soft and plush - absorptive - while other rooms are hard and reflective. TruePlay is Sonos answer to helping mate their speakers to rooms through innovative engineering. I think it is awesome. With a relatively simple procedure, one can improve the frequency response of his/her speakers just by walking around and waving your phone in the air. How cool is that.

One thing people should try is pick several of your favorite tracks and then enable/disable TruePlay tuning for that room and close your eyes. I have done this and much prefer the tuned version as opposed to the previous default EQ. I think the vocals is where I notice just sound more life-like. Even when listening to NPR over the radio - they voices just sound more natural.

A great big thanks to all the Sonos engineers that made this a reality. Over time it will get even better.

I think this is a real game-changer!

Rock on.

Gotta say... I swear someone fell down the stairs today but it was the bass response out of my Play:1s. Never had that level of awesome out of them!
