Subwoofer Choice Question SVS, Majico, JL Audio, REL

I have a pair of SVS-3000 subs. I have enjoyed them and they offer  a lot of bang for the buck.  I recently purchased a pair of the Fleetwood Devilles which I like very much.  Looking to upgrade my subs to match really well with my Devilles. Will be used for 2 channel music only. Want musical and  articulate bass that enhances and integrates well with the Devilles.  

Options are :

(1) SVS only this time going to the SVS-4000. Relatively inexpensive and I love their setup app.

(2) Magico A3Sub-built like  a tank, expensive though I can get a reasonable deal on  a pair and Magico will assist with the setup through REW

(3) JL Audio Fathom F112 or 113 V2- Good bang for the buck, lots of fine tuning available

(4) Rel (any of their carbon based subs)-Biggest concern is no phase adjustment. I am limited to where the subs can go so don't understand why they provide no variable phase adjustment.

Thoughts and comments welcome.
