Looking for a new Subwoofer


I am looking to replace my Definitive Technology Supercube 6000 with a new subwoofer to augment my Fyne F-702 speakers. My listening room is about 13 x 22 ft with 8’ ceilings and an 8’ opening to the dining room to the left of the listening area. I try to avoid major products made in mainland China—in spite of their at times very good quality, and I have narrowed the brands down to Paradigm, Vandersteen, and JL Audio, specifically, a single Paradigm XR11 or dual Defiance X12s, the Vandersteen Sub Three with “required” crossover, and the JL Audio Fathom f110v2.  My budget is about $4K, with the XR11 and Fathom right at that price, the dual X12s at about $3K, and the Vandersteen with required crossover at about $5300 (including two crossovers, as they are sold in pairs).  I may be able to audition the Paradigms and the Vandersteen; a friend has told me the room correction software with the JL Audio sub is way behind that of the Paradigms.  In light of the excellent advice I have received in this forum, I wonder if folks out there have had an experience with these subwoofers and what they might recommend.  Many thanks.

Rythmik are great subs that I've heard in numerous systems/ rooms.  Doesn't mean they are for everyone or that a single sub heard once was set up well.  I know someone struggling to get bass in his room trying different subs, up to 4 subs, room treatments,  modifying room, and experimenting now with room correction, and still currently struggling. 

Despite hearing the Rythmiks match up well with my very articulate and natural sounding Daedalus speakers,  I decided to order a pair of Daedalus passive subs  with Daedalus external crossover.  I will definitely keep the Rythmiks for another system,  but am anticipating being very impressed with Daedalus BOW subs.  I try to buy used when I can like I did with my Daedalus speakers, but never see these up for sale used.  Doesn't hurt that when looking for WAF for dual subs that you are getting beautiful real hard wood finished to your specifications.

@grislybutter  What the hell does this even mean???  Making up your own little language might be fun for you in your own strange world, but to the rest of us it’s just meaningless and helpful to no one. 🙄

I never understood this Rhythmik infatuation I read about from time to time here. I heard one once, and it was just ok.

What model did you hear, and what kind of gear was feeding it?  How was it tuned?  WAS it tuned?  They are highly adjustable, but if the owner is clueless on how to set them up properly, then I'm sure they're capable of sounding just "okay" or worse.  

The "infatuation" you speak of is for good reason, IMO.
