Subs for SF Amati

I enjoy pair of Rel 31 right now.

It is mated with Scaena 3.2.

It sounds fast but textured.

You may get just one Rel 31 first and then add one more later.😀

Um, go with 15" and be done with this.

It's an absolute myth that big drivers are slow.  They are not.  What happens is that integration is a PITA no matter what you do.

Take a look at the AM Acoustics room mode simulator and try to keep your listening location, speakers and sub out of the lowest modes. 

Measure and clip any peaks so that you can bring your sub up enough. 

Plug your main speakers if they are ported, this will help you raise the crossover point, minimize IM distortion on your mains and let the subs do what they do best: Amplify your dynamic range.

+1 for JL Audio, but you pay a lot for the excellent room correction. 

and get the JL Audio CR-1, it makes integration a breeze - and with endless flexibility for current and future main speakers...

Subwoofers can not beat the laws of physics. Play a 20 Hz test tone at moderate volume and place your hand on the sub's enclosure. It will be shaking./ Newton's third law. Any shaking or vibration of the enclosure = distortion. 

Balanced Force subwoofers place identical drivers on opposite sides of the enclosure operating in phase. The forces generated cancel out and the enclosure remains fixed in space. Any vibration left is cabinet resonance, another significant problem with subwoofers. Balanced Force subs are currently made by Martin Logan, KEF, Magico and me. Me is way too expensive:-) All other subwoofers are fatally flawed including Rels and JL Audio. Eventually they will all come around and use balanced force designs.
