Looking for a new Subwoofer

Definitely go with two subs over one, and I wouldn’t recommend the XR11 for music because it’s ported, and especially the lower JL Audio subs have known reliability issues so I’d cross them off too. If it’s me I’d get two Rythmik F12G subs that are an outstanding value because they sell direct (made in Texas BTW), and a pair will only set you back $2400. Not only are these subs supremely musical but they’ll go down to a honest 14Hz, and Rythmik offers excellent customer service and a 45-day trial period (not including return shipping). This one’s a no brainer to me, and here’s a link with more info. Best of luck.

my 2 cents:

everything about the Fyne F-702 screams that they go down to cover the bass frequencies (30Hz) and do it well.

To add a sub to those without massive overlap is challenging. You either cut off the lows of a full range speaker with crossover control or you double the lows almost all the way, both are questionable approaches. I would get the least powerful 10" or 12" subs (2) and see if they improve anything. I spent a year trying different approaches until I successfully dialed them in.

I ended up ditching the crossover and turning down the subs to 85Hz and very low gain. They just add a subtle accent to the lows, helping with the soundstage, but helping a lot.

@grislybutter There’s almost nothing I agree with here. “The least powerful sub?” Really??? If you position a good sub(s) properly and set the crossover, volume, and phase with any care whatsoever then good subs can blend seamlessly with most all speakers. That the speakers go down to 30Hz is totally irrelevant. 🙄 My speakers go down to 28Hz (-3dB) and I can easily integrate my “lowly” SVS SB2000 sub completely seamlessly. If you can’t do that then you really just don’t know what you’re doing IME.

For Soix, I checked the Paradigm website, and it states that it is a sealed sub.  However, many thanks for the link, and they look pretty good, so I will have to check them out as they are made here in the USA and are very reasonably priced.  Now, to convince the wife about putting two in the front room.  Thanks again, as usual, your advice is good.  Time to hunt down some reviews.

Sorry, my bad.  I meant to say the Defiance X12 is ported.  The XR11 is obviously sealed but is also $4k.  I’d take two Rythmik F12Gs for $1600 less than one XR11 all day every day.  Not even close.
