KEF KUBE 10b or 12b w/LS50 Wireless?


I’m thinking of picking up a sub for my KEF LS50 Wireless speakers and am eyeballing these two.  The room in question, my man cave, is about 15’x15’, about 10’ ceiling. The speakers sit on my desk about 60” apart.

Is the 12b overkill or will it work well? I’m sure the 10b is enough but for another $100 I can have a setup that can move into a larger room later if I want.

Thanks for any input.

The LS50 is an excellent speaker for sure, the Kube will fill in the missing sub, but without the same finesse as the LS50. The 50’s do work better on stands and IMHO have plenty of low end when set up right. R400b would be a better match, used prices should bring one in on budget 
Thanks for the input anygreg,

I’ll checkout the R400b.  My other option is a SVS SB12 NSD which I have and am not currently using.  Floor stands won’t work as they need to be on my desk.  I do have some IsoAcoustic Aperta stands I could use but I don’t want to make the KEFs too high from my sitting position.
They are great stands by the way, I use the KEF X300A in my office desk mounted and they are fine, or should I say, good enough for the purpose etc.

i was at the official UK launch of the LS50 and the new LS50w, both are excellent speakers, with the latter outstanding value and quality. They really do shine in the right environment.you will have to be careful you don’t detract from this when adding a sub (or boom) hence the r400b may fit the bill better as it is more refined and very capable, but fits the Kef signature sound, now the Ref 8 is a whole other proposition. Good luck with your hunt, which ever way you go  you’ll end up with a nice sounding system 
Thanks again anygreg,

Yes, I'm excited about my man cave setup and what I can do with it. I'd say even more so than my family room/main setup. On the stands, you mean the Apertas? Again, I can't have floorstanders. I was also thinking about putting 12"x12"x.5" granite tiles underneath the KEFs, maybe also some 2.5"x.25" sorbathane discs underneath the granite between it and the desk. I could put the Apertas on top of that combo too but I don't want the KEF's too high and the Apertas will raise them at least 3".
The good old man cave, it’s about the only thing we men have left that allows us to flex a little testosterone, we’re a dying bread my friend lol.

Yes I was referring to the Aperta stands earlier.  The LS50w was designed in a way to make it as easy to fit into any room and sound good, however having heard it in many different environments it does shine in some more than others. The onboard software in the app does help alleviate some of the shortcomings or issues in the room/desk etc

as with most things hifi, it’s like a Rubio cube, you complete one side to find the other side isn’t complete anymore, this is what keeps us pushing on until we find it perfect sound/setup or audio nirvana.  Or you could do what I did when I was a kid and pop the corner off the Rubix cube and put it back together complete 😂 

you wont go far wrong with KEF kit in my opinion, great bunch of dedicated guys, fantastic factory in the UK where they build everything Refference and above. Their sound just suited me when I first heard it many years ago, ever since I’ve always had a sweet spot for the kit and ethos.
