Subs for SF Amati


I’m looking for recommendations on subs to pair with Sonus Faber Amati Traditions paired with Mc monoblocks. I currently have a pair of REL T9x, but they are not going deep enough and I do not think they can keep up with the Amati. I’m considering a single REL No. 31 (a pair would be great but not in the cards right now). Thoughts?

Thank you all for very helpful input. SF Gravis is an interesting thought, although I wonder if a company like REL that focus 100% on subs would have better performance. I know there are different perspectives, but I’m definitely in the camp of using subs in 2-channel. For my system it has significantly increased the sound stage and the weight and depth.

It’s interesting that there a lot of high end speaker options but not many subs.

the gravis VI from Sonos have two drivers in one cabinet.

So this would seem better than a pair of subs. and Actually cheaper although still very expensive.
