Sonos sub, not impressed

You cannot bond a passive subwoofer to the FIVE’s with this scheme, but you could Group the AMP/passive subwoofer with the FIVE’s. I don’t recommend this scheme because there will be some very subtle synchronization issues and you will not have a proper crossover for the FIVE’s.

So I would need to do it with wired speakers then?

 Could the sync issue be why I’m not happy with it currently? I use the 5s and ones together with the sub bonded to 5s

Sensitivity to the potential sync issue varies between individuals. I’m hyper about this. Many people don’t seem to notice. Probably the insensitive individuals are better off. There are unavoidable network variabilities and an occasional packet will be dropped and need to be resent. Each player has its own connection details to deal with. SONOS works with a 75ms data cache. If a packet is lost, data in the cache will be used and the player will slip behind by one data block. Eventually, one or more cache’s might empty. From time to time SONOS will realign the sync. and refill the cache. If you are are sensitive to this sort of activity, you’ll perceive a gentle shift in the stereo image or alignment with the subwoofer. As I said personal sensitivity to this varies. In your Group’d SUB scheme the risk of detectable sync events is higher.

In my opinion a more significant issue is lack of a bass crossover for the FIVE’s. Both the FIVE’s and SUB will be delivering bass. There will also be some unnecessary midrange smearing in the FIVE’s. A  crossover prevents this and this is one of the benefits of adding a subwoofer with a proper crossover. Also, there could be bass sync issues between the two speakers covering the bass.

You say that when you connect two fives and a sub, the sonos five don't work in full range? Do they start from the sub frequency cutoff? It should be able to be added and thus obtain the complete sound of the five, in that case it is a waste

No subwoofer/speaker combo designates each as full range.  That would cause a bloat in the overlap.  There’s alway a crossover, and it’s not a brick wall.  As the frequency goes down, the duties gradually shift from the speakers to the sub.  This is a GOOD THING!  Sub frequencies take a lot of power, power which is robbed from the upper frequencies.  When the Sub is handling these power robbing low frequencies, the Fives will be freed up to better power the frequencies they do best. 

I understand, I said it more as to also take advantage of the low frequencies of the five and not that these frequencies are controlled only by the sub, thanks a lot for your answer 

The FIVE’s incorporate a “crossover” that passes the extreme lows to SUB and removes them from the FIVE’s. There are two benefits. First, there is no double dipping of the lower frequencies. Second, since the lowest frequencies sent to SUB are removed from the FIVE’s, the FIVE’s will have a simpler job and the midrange will be clearer.

Thank you Buzz, I understand that, the range frequency will go from like 20hz to 80hz (Sub) and from 80hz will start the five´s.  I just like to feel a lot of the lows frequency, since the sonos five are very efficient in the mids and high frequencies.  Grateful for your response

A crossover doesn’t work like that.  It’s not a brick wall at 80 Hz, 80 Hz is just the midpoint.  It is actually gradual, with overlap, over a range of frequencies.

Buzz let me ask you something since I have read your comments with very good knowledge on your part. I have my home cinema in the living room with Beam 2 gen, sub mini and two play 1 and also on one side, two sono five and a Sub, when I group the two areas to listen to music since they are in the same room, the subs seem not to add up, as if they cancel each other out, I don't know if I'm explaining myself correctly, they are not close to each other, but it seems to harm instead of benefit
