@soix Haven’t tried yet, but the Rythmik F12G is so much faster than the SVS SB2000 that it’s really in a different class. Is a different type of technology altogether.
My plan for when I try putting them into play together is to use a copper power cable on the F12G that I know sounds slower and more smeary and an 11awg 7N OCC silver power cable (which I normally use on the F12G) on the SB2000 to attempt to split the difference in apparent rapidity of response. Not sure if the SB2000 will get anywhere close in speed because of the silver, but my testing in the past showed that it was very responsive to changes in power cables. Much more so than the F12G.
