Sonos Amp and 3rd party subwoofer issue

I have the same issue with a SVS PB12 Plus/2 sub out from Sonos Amp does not play. The sub works fine on other sources, ive called Sonos support but they could not fix it after having looked at logs..... Might have to return the Sonos amp, which is sad, cause it seems like something that could be fixed.

We have the same problem - A well working powerful sub (Bowers & Wilkins) that recieces no signal from the AMP Sub-out, no matter what we do. I see in that the discussion here is up to 5 months old and there is still no explanation on how to fix it. Keith - have you posted a solution somewhere else?

Please advice us. I do not want to hand the AMP back but will if it does not work as intended.

Just to be clear, you're not using the Sonos Amp to power surround speakers, are you?

We have tried both, surround on and off - no difference with respect to the Sub out signal.

It seems obvious from the preceeding discussions above the many have the same problem. I expect Sonos to come up with a solution well within the 5 months that this problem has been known.

I don't work for Sonos, so I can't give you any insight into whether this is an issue or not. I do know that when the Sonos Amp is set up as powering surround speakers, the subwoofer out is turned off, since the only signal being sent to the Amp is the surround signal, and not any of the additional LFE signal.

Have you submitted a diagnostic, and contacted Sonos support, or are you just posting anecdotal data here on the boards?

I do not see the point with submitting yet another diagnostic of the same problem. Several have already done that, without any solution posted so far.

It’s the contact with Sonos support that is the solution. Posting here on a community board doesn’t really further the data about the issue. If Sonos can’t see and reproduce the issue, all the “me too’s” in the world won’t help. Give them concrete data, and call in to discuss it.

Calling is best but you'll at least get your diagnostic looked at if you use one of the 24x7 support options or even e-mail. These boards do little to help the Sonos tech that visit from time to time find posted diagnostics and even then there is often too little data to do anything with them.

See the Contact page and make sure it is set to your country and then pick an option.

I've been using a Sonos Connect Amp to power in ceiling speakers and a Martin Logan Abyss subwoofer in our master bedroom for years. Swapped it out for the Sonos Amp as I'd like to use the Connect amp for another set of speakers. After hooking it up and playing the same music/sources, the subwoofer is severely lacking. I checked the sonos settings and the sub is enabled. I adjusted the crossover and have the sub level in the middle, sometimes the sub won't even come out of standby. I used to keep the subwoofer set to level 3 and the Connect Amp sub setting in the middle and it was plenty of bass. Now I have the subwoofer level set to half volume and the sonos sub setting almost all the way up and it still doesn't seem to produce the equivalent amount of bass. No other changes have been made. I'm contacting support now to see if they have any input on this. I'm pretty disappointed so far.
