Sorry this is not one of the 2 brands that you mentioned but I have been very happy with my GSG Devastator. It has a 21” lavoce driver in a semi horn loaded box. It’s big but we use it near field as a coffee table. There are 2 versions. The home theatre tuning and the music tuned one. I bought the music tuned one and it’s very effective down to 27hz. The HT version goes lower. It’s a passive sub and the diy flat pack and driver will run around 1500 with shipping. Then you get to build it and find an amplifier. I’m using a behringer DSP amp and am happy with its performance for under 2k all in. It will pressure up my 20x20 room more than I can use. It can get almost uncomfortable. I used an SVS PB16 ultra prior to it and it was a huge huge difference.
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
