Recommend a sub for Kef R11 Meta

Subwoofers are very room dependent.  Can you tell us about your room and the music that you like to play?  

If you have the space, I would also recommend 2 subs.  I have 2 JL Audio e-110’s, and they blend great with my Raidho XT-2’s.  I did buy them at least 5 years ago and the price is now up to $2,200 each.  I think that they were around $1,700 each when I bought them.  They got a fantastic review by Jonathan Valin of The Absolute Sound way back in 2014.

I am looking at the same REL HT-1205 for my home theater.  IMO it would be a great choice as well.

I have been warning folks on Audiogon about spending too much on powered speakers/subs.  Expect that any powered speaker/sub will likely last about a decade or perhaps longer if you don’t use them that much. If they fail, Class D amps are notoriously hard to repair and costly to replace.  Keep that in mind.

SVS SB-2000 Pro would be my choice to try since they offer a trial period. 

+1 Rythmik

Paired Rythmik F12SE with my R11’s. Great pairing, very musical. Great SQL. 

Agree with the comments of 2 subs to match your 2 towers.  I’ve had a great experience with SVS and RSL subs.  My favorites for music in a tight space are SVS SB 1000 Pros.  I also have a SB 3000 and SVS will be releasing a new 3000 sub line. I prefer sealed subs over ported for music listening.
