Sub to complement KEF LS50s: SVS vs. Rythmik


Hi all. I'm considering adding a subwoofer to my current set up: Bluesound NODE2i (Tidal MQA) to Cronus Magnum II to KEF LS50s. I'd like to supplement the KEF's on the lower ranges.

I'm considering 2 subs and have located a few deals:

  1. Salk Sound Rythmik F12 in white for ~$1100 
  2. SVS SB4000 for ~$1200

I particularly like the room control on the SB4000, but am not wed to it. Any thoughts between the two? Anything else you'd recommend in this price range?

A few other notes: room is 12 x 30 feet, with a wall of windows (NYC condo). Acoustic paneling is next! Likely don't need all the size/wattage that either of these subs provide. Perhaps getting a MartinLogan "X" with the room correction could suffice, but would rather buy top notch and be done with it.

I'll utilize this for 75% music / 25% movies. Music tends to be bluesrock/jam bands/jazz

You could try two Gallo Acoustics TR-3D subwoofers like I do with the LS50s (I actually have the older versions). Also live in a NYC apartment about the same size, and they fill the room for music and movies. They have a small footprint and aesthetics that don’t look bad with the speakers. I haven’t tried room correction just setting them to crossover at 70-50 hz. Have the two shooting from the front, but I think it sounds best with one in the front and one in the back. Hope this helps.
has anybody tried small.. like 8 inch or 6 inch subwoofers? Is their such a thing with proper extension and frequency response?
I’m currently using LS50 and two SVS SB-16 Ultra and I have been SUPER impressed with the SVS subs.  The only down side I can mention is size and weight.  Besides that, they integrate perfectly with the LS50 speakers.  The sound stage is wide and open with incredible 3D imaging.  Of course, most of the time with music the subs are invisible completely and barely moving.  I’m using 70hz crossover.  Most importantly, I recommend two subs versus one for all reasons mentioned above.  Good luck!

Without trying to sound so intelligent, I think the SVS SB4000 is an excellent choice.  I've had a few subs in my systems.  I've had the Velodyne ULD 15, Velodyne F1500R, JBL 8400, and NHT's SubTwo.  Only the Velodyne's were as musical as these SVS's.  I go with a two channel application with NHT 2.9's driven by an ADCOM 555 MKII.  Again, these are the only subwoofers that have allowed me to say goodbye to my Velodyne's in my head.


P.S.  Because of all the glass in your house, I would recommend the isolation system by SVS to cut down some of the rattle & shake of the room.  It will just be tight and quick!
