SVS SB-2000 Pro/3000 vs. REL T/7x

Love my PB 2000 pro. Have a couple pre-sets, one for jazz the other for rock. For my purposes it performs flawlessly and folds into my overall system quite nicely. The ability to tune it on the fly from the comfort of my chair depending on my mood is great. I've never heard the REL, but hear great things. I can only compare to subs of my past, Velodyne, EV (homemade) and Monitor. 
I know I say this often, but i pine for the days when I could go to a couple shops and let my ears be the judge. Specs and all are great and give clues, but paint an incomplete picture.  

"I gave an answer. But you aren't looking for answers are you? Maybe someone will come along and argue with you."....you got your answer more than once and you argue the responce..and you call me a troll, lmao...my pants are not bunched up as i dont really care what you buy as most from the lack of responce to your post but it reads you decided not to buy the better product and your trying to get confirmation of that decision...so again good luck

Interesting topic, but a shame some apparently don’t like the idea of differing opinions. Rel has established a strong name in the audiophile community.
By all means Rel seem to be the lesser product in terms of performance, by a significant margin. Money which in the case of Rel seem to go towards a nicer finish and more expensive, though less ideal amplifier type.

all that said it’d be interesting to see more comparisons.

Both sealed.

This is Incorrect. The T/7x is not sealed, it has a 10” passive radiator on the bottom of the cabinet.

I currently own SVS, REL and Rythmik subs. Used 100% for music. I would choose either SVS or Rythmik over the REL. Besides being cheaper the SVS and Rythmik give you more options for better integration with your mains.

REL will give you very fat bass, which sounds rather cool until you realize that’s not how bass actually sounds. Kick drum beats in real life don’t actually last as long as they do when reproduced by a REL sub. The SVS sub will be tighter, but a tighter sub can be more difficult to integrate because it will be easier to hear when the crossover frequencies are out of phase.
