All three manufacturers make fine subs.
I have owned two JL F112 (original version) for about 15 years. During that time, they each have had to go back to the factory twice for problems. To JL’s credit, they did the fourth repair at n/c after I complained. The subs also emit mechanical hum, necessitating use of an AVA HumBuster on each.
If you are thinking of new JLs, they are better in terms of adjustment (easier to use and more capable) than the old ones. I believe JL has upped the specs of the capacitors (the point of failure), so perhaps new ones don’t require as much maintenance. I don't know if the new ones hum.
I have owned two SVS SB-3000 for a couple of years. They also are excellent subs and have plenty of adjustments -- more than my JLs. I also like the ability to adjust from their app. I have found SVS customer service excellent. Unlike my JLs, the subs do not emit any hum; they are dead quiet. They also are far more cost-effective than the JLs.
REL has many fans. What has troubled me is the firm’s insistence that speaker-level connections are superior to like-level ones, which seems like marketing nonsense to me. Yet many people love them.
You might consider a couple of SB-3000 or SB-4000 to replace your current subs.
P.S. Mine is a music-only system. No video.
