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?

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.

As a result, Rythmik subs are generally reported to have lower, frequency-dependent group delays (GD) than REL subs. I wish I had measurements to show you. On the other hand, REL subs are still often rated as more musical, mainly because they tap the speaker-level signal and can integrate more seamlessly with the main speakers, introducing much less perceptible phase shift. As a comparison, SVS subs tend to have relatively higher GD than the nominal 1/f. I have tried two of them (SB‑1000 and SB‑2000) and found that they are not quite as fast or as precise.
