Full range from CONNECT:AMP's subwoofer output

Hi there Larry,

I'm afraid there isn't a way to alter or disable the 80hz crossover on Sonos. When an RCA cable is wired to the subwoofer output, the CONNECT:AMP will automatically adjust the crossover frequency. If you'd like, I can change this to an Idea thread if you'd like to see a feature like this from Sonos in the future.

Thanks.

Hi Ryan,

I agree with Larry - It would be nice to have the option to change the subwoofer out to full range eliminating the 80hz crossover.  It seems like this should be doable.  Can you please help?

Thanks for the feedback, Luke. I've changed the topic to an Idea thread so others can +1 and comment on this request as well.

I also am with you guys Having this freq. locked is a disappointment. It should be configurable within the component's settings. Depending on the powered sub and or the wired speakers you can really experience a sonic gap when the sub only kicks in at 80Htz and lower!  The work around I utilized and found to work well is I got a different sub that has speaker level inputs.  I was able to use this configuration to get the Sonos connect:amp to output the full range of frequencies to the sub and then use the sub's crossover to do the filtering.  Not as clean of an install but is getting the job done!

Yes, please try to get this implemented as soon as possible! Thanks Stefan

I would just like to add to the voices asking for the ability to set the crossover frequency manually. Those of us that put money on good speakers and gear the cost of an C:A, want to ensure we can blend the sound properly - and also manually disable the subwoofer in software (without physically disconnecting it) at times, to get the full range of our mains. I was completely baffled and disappointed it was not like this, when I paired a new KEF Q400B with the B&W 685s I had connected the Sonos. Please work this in soon. Thanks!

With the software focus on voice control and streaming services and hardware focus on active speakers that the play units all are, I don't see when this will happen, and even if it will happen. Speaker level connections, if the Sub can take these, are the only possible work around, short of buying a Sonos Sub.

That said, 80 hz works quite well in a wide range of speakers, except for very small monitor style speakers, which the 685, for example, is not - it is quite capable down to 80hz. I am curious why more than what the Connect Amp does is needed in this case.

5 people in two years is not a compelling case for Sonos to spend time on this request. I assumed that the request was allow people to lower the crossover, to say, 50Hz for more capable full range speakers, rather than raising it. As Kumar says however, any decent sub will have a high-level connection which would be more suitable in this sort not case (also lol'ing at the idea the C:A is an "expensive" amp...).

Thanks for your interest in the thread Kumar. As The LHC noted, the point would be to set the crossover LOWER than the 80 Hz, so that you can get your mains going as low as possible in stereo and optimal positioning (which the subwoofer is normally not). You don't want the sub handling any frequencies your mains could handle, ever. The 685s will go to 52 Hz and I'd rather have them playing the 60-80 than the sub on its own.

Since SONOS evidently already has the feature enabled for the SONOS Sub integration, it would be a trivial software matter to work it in for the rest of us. I know they aren't trying to cater to audiophiles but this is a fairly basic function of any decent stereo amp. Keeping things "simple" at the expense of sound quality is the apple approach; Sonos clearly tries to strike a better middle ground, but for the cost of their devices, I feel some basic features like this should be standard.

The Sonos Sub has DSP that Sonos knows and fully controls; offering the same flexibility in the Connect Amp with third party Subs may not be a trivial problem. Or it may be so.
I doubt you will see a solution though; I certainly would not hold my breath.
