Truplay with Amp locked to Sonos branded Sonance speakers only?

This was never 'hdden' - my recollection is that it was made clear at the time the Amp was first made public.

It would be untypical of Sonos to do this to promote sales of Sonance speakers rather than for technical reasons. I doubt very much that the financial cut for Sonos would justify deliberately denying the best possible experience to the vast majority of Amp users. But obviously I cannot speak for Sonos.

"untypical"? Well, as an integrator I can say they do a lot of things "untypical" that get a lot of dealers really angry with them, so I wouldn't give them a pass so quickly here.

The specs on the Sonos/Sonance don't look very different from existing Sonance other than pricing. The "specially configured for Sonos" makes us suspicious when there isn't any specific feature or spec that is claimed or disclosed other than the Truplay tuning.

I can run Anthem ARC on any speakers I plug in to the Anthem AVR. That's the whole point of a microphone-based arc algorithm - it measures the actual sound output in the room and then tunes the settings instead of relying on factory settings or arbitrary assumption on the typical room layout which is so variable.

"untypical"? Well, as an integrator I can say they do a lot of things "untypical" that get a lot of dealers really angry with them, so I wouldn't give them a pass so quickly here..

Such as? I am genuinely curious.

Mainly business issues revolving around inventory levels, pricing and pricing/adjustments, availability, and channel conflict. Most are historical and hopefully no longer apply, and it isn't appropriate to discuss here but very common chatter in any dealer forum or discussion group.

Also a lot of historical issues with not providing an official API and cutting off, with very little warning 3rd party integrations that used widely known but unsanctioned integration methods, etc.

I came into the game later (last few years) so I don't have most of that baggage and unlike traditional dealers, I don't rely on selling products on big markups for profit so all the pricing complaints are not an issue for me.

Not promoting here or trolling, but since you asked, I charge for my time/design/install/support and client can buy all the equipment themselves while traditional dealers still want to make a large profit on the equipment which can be impossible when Amazon, Best Buy, and others sell everything close to dealer cost, in some cases.

That's an industry problem, not specific to Sonos but when you start out with big profit margins to dealers and they get squeezed, they have long memories 🙂

When paired with Sonos Amp, the In-Ceiling and In-Wall speakers’ unique hardware signature unlocks Trueplay™ which accounts for the size, construction, and furnishings of the room where the speakers are placed, and automatically adjusts the EQ for optimal sound.

This suggests something electrical rather than an audio watermark (which could be obscured by the room effects). Perhaps the Amp recognises a unique impedance characteristic. I suppose it's also conceivable that the speaker senses a low DC voltage and responds in some way to basic signalling. Intriguing.

OK so you have some business gripes with Sonos. I said it would be untypical of Sonos to deliberately limit the experience of the bulk of users under the excuse of technical limitations, and I stand by that.

The reply above "unlocks Truplay" sure sounds like DRM (artificial technical restriction) to me - untypical or not.

All existing AVR receivers with sound correction work with any attached speaker since most AVR makers don't make any speakers they obviously assume the customer will be choosing their own brand of speakers.

Which actually makes me speculate that Trueplay is not exactly the same as the typical sound correction you get with other AVRs. Trueplay has been out for several years, long before these Sonance speakers were even thought of. If Trueplay could work with any 3rd party speakers, why didn't they give the Connect:amp Trueplay capabilities? There would be no sales benefit to Sonos with that exclusion, since they couldn't profit off sales of their own passive speakers. Perhaps they wanted to discourage sales of the Connect:amp in favor of their own smart speakers that do have Trueplay? Perhaps the Connect:amp itself wasn't capable of Trueplay tuning for some reason?

Another difference between Trueplay and other AVR sound correction tech is that Trueplay asks you to move the microphone about the room, while other tech has the mic stationary throughout tuning. So clearly they are not synonymous. Doesn't prove that Sonos isn't putting an artificial restriction either.

There are other features of Sonos products where they could have easily put in artificial restrictions to boost sales, but didn't. Things like music services available, voice control, airplay compatibility. Although in fairness, the benefit of restrictions would be minimal, and probably not worth any potential loss in customer goodwill.

Also worth noting that the outdoor Sonance speakers do not say they can be trueplay tuned. Sounds like trueplay won't work well in an outdoor environment.

All that said, since you clearly can do some form of tuning with any speakers, it seems like it would be a win for Sonos to offer a level of tuning for those with third party speakers, if Trueplay isn't an option. If it could be particular useful as an option for android phone users. But maybe Sonos doesn't feel like such an option is up to their standards.

Just a minor clarification - although Yamaha and Denon (I think) have you keep the microphone in one place), Anthem gives you a tripod to hold the microphone at ear level, but you move around and take samples from multiple physical listening locations in the room.

And Anthem also has an app that runs on iOS devices using either the built-in Apple microphone or a calibrated external microphone.

They were very clear that they felt using the internal microphone was not ideal because of manufacturing variability and the internal mic can degrade over time and if the vents are clogged, etc.

In case you were not aware, Anthem, unlike most AVR's, uses a separate user-suupplied PC and a special individually calibrated microphone to perform the ARC calculations and not the internal DSP/CPU in the receiver. They claim more accuracy and horsepower, sounds right, but I have no data to prove/disprove that.

Lots of wild speculation around here. Why not simply ask Sonos?

Hey Sonos, do these Sonance speakers include a special chip which identifies them as TruePlay-compatible zone players within an existing Sonos household?
