Subwoofer for Kef LS50 Wireless II?

thanks for the responses
I've used the recommended settings on the SVS app as directed by their support team after advising the of the speaker pairing, I've also done the same thing with KEF support
from there I've adjusted to taste and performed the sub crawl
I'm afraid my room is currently not suited well at the moment for audio, open concept and hardwood floor, factors which will be addressed at a later date
ultimately the tonality of this sub is not doing it for me, I'm not hearing nuances or texture, more of a one note thumper, and a tad too much audible distortion when you push it on a track like Bass I love you, the unit has performed very well on movies
i think i will in fact skip REL due to the inability to connect via high level and start going up the chain further starting with a JL Audio dominion and then possibly a Rythmik Audio F12 G
budget permitting I would like to end this with a pair of JL's 10' fathoms

thanks for the feedback
i think ive been convinced to stay the course with this sub a while longer
i just ordered a subddude
also just heard a very good bass track , Tidal MQA version of Cardi B's Bodak Yellow, this is the first track that this sub has impressed me with, interestingly enough this particularly track it does not rattle my house

update,I now have the KC62, long story short, perfect marriage
integration took seconds with the app, set it and forget it, no looking back
trying to resist the urge to purchase a second unit
it does not have the output capability of the SVS
app control on both units is superb, I'll never do subs again without app control, no going back, I read a blurb somewhere that both JL Audio and Velodyne will be releasing new app controlled products

the KEF's with the KC62 for the right room and music preferances is without a doubt a killer killer value in the world of two channel
the whole system is just set it and forget it excellence, I'll stop short of calling it endgame but it ticks a good many of those endgame boxes

I'm also very interested in what JL Audio may have pending
Velodyne too but with an asterisk,  the real Velo was doing things far ahead of its time, curious if the new owners can do much to further David Hall's work

Perlisten's 12" offering appears in line pricing wise with JL and looks incredible
I've just ordered an SVS SB3000 just to compare against the 1000, I have a feeling it could be the sweet spot in the SVS lineup for music

back to the KC62, seems to be getting better with break in, re-positioned between the two speakers,  drivers facing forward/back
completely unobtrusive, if ever there was a living room sub this is it and still in awe of the weight on this thing, around 20% heavier than the sb1000 at half the size

quick updateswitched subs and am currently on the SVS SB3000
this change has been significant for me in my room, could not be happier at the moment,

the SB3000 thumps and gets closer to that hitting you in the chest feeling that the other two couldn't, sound quality is about the same, maybe a slight edge to the KEF......the SB3000 is still not into ultimate bass slam territory, no DB measurements from my end, I have gain at 50%, most tracks won't sound well above that, I can hear the limits of this unit past 50% gain, still fun though at 100% from time to time with a well recorded track,  my room actually sucks for sound and remains untreated for the time being,

svs recommended stock settings on the app for the KEFs with the exception of both high and low filters set to 80hz

the other two subs seemed to add bass only while this unit appears to add to the overall musical presentation, 

the gloss version I have is surprisingly living room friendly and about as nice as you can get before stepping up to some of the super premium finishes$$$ by the likes of say JL and REL

this is a poor mans set it and forget it end game music system, what KEF has done with the speaker system is special but a sub is an absolute must and the SB3000 appears to be it, of the usual contenders, I can only envision a JL Fathom trumping this unit

all of the above refers to 2 channel music
