Paradigm or JL subwoofer


I am making changes to my 5.1.4 system. I use it for home theater and listening to music.
I have a Paradigm SW 1000 Prestige sub. It was suggested to me that if I am upgrading my system I should have two subs. I listened to two JL Fathom f112v2 subs. The sound was great. They would cost probably $9000. As I already have the Paradigm SW1000 sub, I am thinking of just adding another one for $3000 and saving $6000 that I could use for better electronics such as a Lumin T2 streamer. Would two Paradigm 12 inch subs be a major drop-off in sound quality compared to the JL's. Thanks

Long and short, 2 is better then 1.

I'd double up on what you have already, which is what I also did when I was entertaining a costly sub upgrade.

I'm happy with my double KEF set up, as opposed to buying two new SVS sub's.
Yes it does not make sense at all to take a big loss on my Paradigm sub. I have no doubt I could have bought something better for less money but at the time I thought it was best to match the sub to my speakers. I will buy a second one

@m-db Thanks for your post. If possible can you explain to me why the JL CR-1Crossover is critical. It costs $3000 which is a lot for my budget. I was told my Anthem 1120 has a crossover built in. If the JL Crossover is that important to my system I would consider.
My system is home theater, 5.1.4 but I am looking to change it to 7.2.2. I am definitely adding a second sub. I love watching Atmos movies with my system.  I am really looking to upgrade the sound of listening to music. I stream Qobuz, I am thinking of replacing my Bluesound Node 2i with the Lumin T2 which would be a huge expense. It's possible to buy the JL Crossover and not spend the money on the Lumin T2. I also stream via the Conrtol4 app with my Anthem 1120 and I think it works better than my Bluesound. Thanks
