Indeed, having them both at home is a good option.
I’ve been reading a bit about the subwoofer crossover thing ( didn’t know what it was)
If I understand correctly what you mean, the speakers I have don’t have a lot of base at all , maybe 80 hz for a standard sub connected to the sonos Amp would be a bit too low , and I would still miss a bit of power in the lower sound range.
That would make the sonos sub a better option, cause the wireless connection to the amp + the software will make it able to tweak the crossover output.
I wont be able to put a sub centered between the speakers, does that make a difference ?

With small sized speakers, the lesser the bass they have to deal with, the better they can do the rest of the music. Hence, higher the crossover the better for such speakers - this, in addition to your correct understanding.
The issue with bass above approximately 80hz is that most people can hear where it comes from - so you don't want it to come from a corner because you will hear it so and it will sound unnatural. Hence the advice to keep the Sub in the centre if you are crossing over much above 80hz.
Simplest way to compare is to crossover the Sonos Sub at 80hz, keep it where convenient, as you would the other Sub, and buy the one that makes the most pleasing addition of bass to your music sound/experience. Note that for both Subs, it is a good idea to move them around within your zone of convenience to see where they seem to do most for the experience.
Note also that with a crossover above 80hz, it isn't essential that the Sub is exactly centred - it just needs to be approximately so, lying in about the same plane as the two speakers it is meant to replace for bass duties.

Hello from Romania.

i Have noticed that you have the quad 11L speakers. I own the bigger Quad 22L speakers.
Do you think the Sonos Connect Amp is able to drive those speakers ?
How do you think the sonos connect amp is wrking on stereo music ? Is this a good amp in your opinion ?

I hope i dont buther you with my questions.
Have a nice day
Thank tou !



I would recommend a Sonos Sub, using one myself with a Connect Amp and pair of Quad 11L speakers.
However, the Quads are a stand mounted small enclosure type compared to the floor standing Zensor 5s - I would question the need for a sub with them.
But if you must have a sub, either get a Sonos Sub that can be crossed over as low as 50hz, not using the sub out on the Connect Amp which has a fixed crossover of 80hz that doesn't quite suit the Zensor 5s. If you prefer a third party sub, see ones like RELs, that allow a high level input, where they are connected to the speaker terminals on the Connect Amp and not its sub out that does the 80hz crossover.

The Connect Amp is as good as any other up to 55 watts/channel stereo amp in the market today. Mine works very well and has replaced Quad amplification because of its convenience.
It will drive the 22L quite well too - as well as any other up to 55 watt per channel amp, if you are using that type today. But if you want it to go very loud in a large room, you may need more power, something like 100-120 watts per channel.

No idea, I haven't used it. In general though the quality of the music is much more dependent on recording/mastering quality. I have a lot of excellent jazz from ECM, bought on iTunes in lossy 256kbps files. It sounds better than some of my CDs that I have ripped using lossless, both played through a Connect Amp + SUB + third party speakers.

Really ? Statements like that suggests you've had every amp on the market today or at least heard a good variety.

I've had the connect amp myself.....sent it back pronto as a cheap vintage Sony receiver sounded better to my ears. It may be good for bookies in a smallish room, but I'd look elsewhere to drive towers to higher spl's in a medium to large room.
