I also sold my REL S812 and bought 2 Rythmik G22s, much better low bass, tremendously better integration, just as tonally accurate - or at least similar, but most likely due to the servo, a little less immediate.
Regardless the Rythmiks are a really nice step above the RELs for music, but I have different subs for HT as the G22s are just too clean and refined for those needed sonic movie thumps.
P.s. jeffvegas, I used to think like you, untill I did an A/B comparison. To each their own.
