ARC Ultra and two sub mini’s


Forum|alt.badge.img+1

What is the technical limitation that keeps the ARC Ultra from being paired with two sub minis? 

Best answer by Airgetlam

The only information we, as a community, can suggest is that Sonos has indicated that one normal Sub is better than two minis. They have never shared any technical reasons, pretty much for any software decision they have made.

Sonos software.

Exactly. That is why I’m asking for a “technical” limitation that precludes it.

There is no scientific evidence that one sub is better than two and there are viable reasons there are multiple subs in dedicated Home Theater setups and movie theaters.

As I suggested, the Sonos software precludes this. I understand your argument, but Sonos makes their own decisions. You could equally question many other choices they’ve made, but never explained ‘why’, we in this community can only guess.

And further, it may be (and at least I suspect) not a technical limitation, but a marketing decision.

There are development and support costs associated with the feature. I can imagine this feature was omitted in order to keep costs lower — allowing a lower selling price.

Nonsense. If it works with Sub 3’s & 4’s absolutely no reason it would not work with Sub mini’s. There is nothing needed but an LFE signal sent by ARC Ultra to the subs at which point subs internal electronics convert signal to audio in proper phase and frequencies.

Who cares what the reason is?  You can’t do it, and all the rationalization (or arguing with your fellow users here) isn’t going to change that.

Sonos software restriction but you can bond two Sub Minis using a 3rd party app.

Exactly my point. NO technical limitation contrary to those making up excuses for Sonos about processing power, etc .

Where has anyone said anything about “processing power etc”, ​@MiamiC70? Indeed, I don’t think anyone in this thread has said it’s not technically possible. They’ve just tried to explain to you some possible reasons why Sonos doesn’t support what you want. Please don’t shoot the messenger! I think they probably agree with you that it’s almost certainly possible technically.

It’s 100% possible since it can be done.

But why would you want this if Sonos deems it unnecessary (if indeed there would be no technical reason)?

It doesn’t matter if Sonos deems it unnecessary, if a user wants to use 2 Sub Minis then they can.
