I currently have an arc, sub gen 2, and for rear surrounds a One and a One SL. If I upgraded to the arc ultra with the gen 4 woofer, can I keep my gen 2 woofer and combine it with the gen 4 one for a dual sub set up? Or do both speakers need to be at least gen 3? Wasn't sure if I could use a pre gen 3 sub with a post gen 3 one. I'm sure the answer is yes but given the cost and how long I keep these things I figure doesn't hurt to triple check.

It’s surprising how much info Sonos provide in a product’s FAQ’s:

Which generations of Sub are compatible with Arc Ultra?

All generations of Sub and Sub Mini are compatible with Arc Ultra. A dual Sub setup requires Sub 4 and/or Sub (Gen 3).

It’s also confusing. The sonos support link from @Ken_Griffiths says: “

Sub (Gen 1, 2, and 3) are compatible with all Sonos home theater speakers.
Sub 4 is compatible with all Sonos home theater speakers except Playbar and Playbase”

That sounds like I could combine the gen 2 and 4 together since “Sub 4 is compatible with all Sonos home theater speakers...”

So to be clear: The answer is NO you cannot combine a sub gen 2 with a gen 4?

The piece you’re quoting in your post here, is referring to a single ‘standalone’ Sub with a Home Theatre Soundbar (including the Arc Ultra) - things change quite a bit when two (Dual) Subs are used with the Arc Ultra. It is explained in the support article under the heading "Using two Subs with your home theater speaker”.

Mr. T

My apologies. It’s not so much “open to interpretation” as “contradictory”!

I wouldn’t say it’s contradictory, you and I both know what it’s trying to say, it could just be made clearer.
