John,
I did a ton of subwoofer research over the last few years and concluded that Rythmik and SVS appeared to be top flight performers with reasonable price tags.
Some of the following is based on my years with the Rythmiks, others based on published test results and my experience on how that correlates to performance. So......a grain of salt might be appropriate
The sealed Rythmiks are really notable for their low group delay and the resultant bass character (some folks might say "fast", I prefer "tight" bass). The relative trade-off vs the ported SVS is that clean SPL capability on the 12" Ryhtmik starts to fade at +\- 35hz. The SVS can go deeper while staying clean and loud, but it can't get to the tight highly damped bass quality of the Rythmik.
I use my subs in a 2.2 ch music only system, so Rythmik was an easy choice for me. In an HT system like the one you propose, I'd certainly think hard about SVS
Good luck
Marty
PS both units allow some control of damping (Rythmik electronically, SVS has plugs for the ports) so there's bit of flexibility either way.
