Cornwall IV and subwoofers

Hello,
Is there a budget for the two subs. On the low end I would suggest the REL T7-9i or X. Starting with the I series they went front firing and passive down. If you have a higher budget I would go JL Audio F series. Like two F110. If you want a whole mother level add the JL Audio CR1 crossover. This you can use with any speakers or subs. You have to be running separates to use the crossover. Plus it has a bypass for home theater. The last option would be the KEF KF92 sub. This is a dual side firing sub that goes down to 11hz. For $2k it’s a good value. Plus they have a wireless kit so placement is easy. If you are in the Chicagoland area this store lets you demo stuff in your home on your system. https://holmaudio.com/
It doesn’t matter how far down your front speakers go. My speakers go down to 25 hz at -3db. Everyone should have two subs. 

Lot’s of good info here. Thanks to all. My budget will flex for whatever gives best sound and integration, and will also fit in my restricted lateral space. Unfortunately, a pair of anything is not really possible, given space constraints, so I’m thinking about just a single sub at this point. If I set it to around 40hz, I doubt it will be directional. I listen almost exclusively to jazz via vinyl and don’t really need to plumb the deepest depths.

I’ve been experimenting with a 15-year old Von Schweikert VRS/1 that I’ve had parked in another system. It’s sealed, 10-in, down-firing, and won’t cross over below 50hz, so it is certainly suboptimal for the Cornwalls, though it is just right for the Merlin TSM that it’s normally used with. Still, I can readily hear the advantages of a sub with the CWs: soundstage opens up, ambience increases, music is more visceral and floats on its foundation. I’m connecting at this point via low pass, and 50hz doesn’t quite mesh to my ears, giving a bit of a hump. Volume is set just to intimate the bottom frequencies, not push them at me.

After reading around, I think I’m leaning toward a Rythmik F12 or F15. They are compact enough, especially the 12, and offer myriad adjustments. Servos get a bad rap among some audiophiles but this version of the tech gets a lot of positive comments for "speed" and musicality.

Has anyone compared Rythmik to some of the other big players like Rel, JL, Hsu, SVS? Curious how it stacks up.

Bill,

I don't think I'd high pass the CW as was mentioned above. Their bass quality down into the mid  to upper 30s is too good to mess with. I'd just roll the sub in and let it do it's thing way down low.

Oz, I'm with you. That's my feeling as well.

@wrm57 ,  FYI,  classic golden age jazz (50s-60s) is my favorite cup of tea.  And, the RELs really augment the lifelike sound that's present.  Surprisingly, even with 1950s recordings--they bolster the ambiance of the recording room.  I was playing Oscar Petersen's 1959 Porgy and Bess last night and the RELs do more than I would even expect on such old recordings.
