how do I connect my own subwoofer?

They could sell hardware and make those of us who have expensive third party subs happy by allowing us to connect a second connect:amp to drive just the .1 sub channel.......

This is never going to make commercial sense for Sonos. I wouldn't postpone any decisions in the hope that this will happen.

Well..... I understand the perspective, but from a purely sales perspective I have to slightly disagree. I only bought a playbar because I could drive my existing reference series rear surrounds with a connect:amp... two items sold. I would purchase another connect:amp if it would drive my Velodyne sub if it won't I'm keeping my old amp just to drive the .1 channel, another sale missed.....

Sonos, like many well run companies, does not run after every possible sale and therefore does not regret every sale missed.
As is known well, the cost of pursuing every possible sale is a higher marginal cost of outlier sales, reduction in total profits and the frittering of development resources that then cannot be focussed on best meeting the needs of selected target markets.

If I’m understanding all of this correctly (forgive me if I’m not), instead of what you suggest by using a “second connect: amp” to drive a passive sub, I would prefer Sonos to update (probably hardware) the connect:amp to allow the Playbar to send the dedicated .1 channel to the connect: amp and then allow you to output that channel using the line level sub output that already exists on the current connect:amp. In my opinion this would make the most sense, allowing you to get left and rear surrounds (speaker level) as well as a sub out (line level) from one connect:amp.

On a different note I don’t see why potential sales of the Sonos sub should stop Sonos from doing any of the ideas mentioned, since the very existence of the connect:amp encourages the use of 3rd party speakers and subwoofers.

Just my 2 cents haha

I just did this. I ran the optical from the TV to my receiver "optical in" and optical from the receiver "optical out" to the playbar. It requires handling sound on/off through the receiver, but I don't mind the extra tap to turn on the receiver. Sub woofer volume is through the receiver and TV/playbar sound is handled through the TV. We are contemplating just leaving the receiver on all the time, but I think that's a little too lazy.

Sound is synced perfectly. No echo or delay of any kind. Sounds fantastic. I guess the receiver and sub wont be sold at the garage sale in May!

And we can spend our money on some more Play Ones to go in the bedroom. it's all good.

Okay, I fibbed a bit. I misunderstood what others were wanting to do. What I have is a sub woofer working with the TV, receiver, etc. NOT the Sonos. I'm happy having it do this, but I can see why it won't work in conjunction with the Sonos.
