Recommend a sub for Kef R11 Meta


I am planning to purchase the Kef R11 Meta.  I am aware that the bass is not as deep as on some of the competitions.  Therefore I will need a sub.

The bass on the Kef though not as deep but very fast.  I will need a sub that can match the speed of the Kef. 

So please recommend some options.  I saw a few adds on Audiogon for the REL Acoustics HT1205.  Is it good enough or I have to spend more?

The Rythmik subs are servo sub.  Does any know if the Rel Tx/9 are also servo’ed?

I've read some user feedbacks and the Rel seems to be a bit more musical.

Depending on budget, it would seem logical to consider a pair of KEF subs as mentioned above. Doesn't it seem logical the KEF would design their subs to match their speakers?

Don’t get caught up on technology.  Either Rhythmik or REL (and probably KEF) will work very well, but you’ll get much more performance/$ with Rhythmik as they sell direct, and they also offer a 45-day return policy.  I’d highly recommend giving them a call. 

At the risk of sounding like a broken record, here’s another endorsement of the Rythmik subs. Like @thriftyaudio, I have a pair of F12SE (with the GR Research cones), and also use an active crossover (in my case a Sublime Acoustic). 
 

In my case, asymmetric placement of the subs worked best for dealing with room modes.
