I have an older ’R-series’ REL (R328, $1600 in 2013) which at the time was their top-tier (now it’s the S "Serie"). Yes it’s good - but not $1600 good.
With that in mind I briefly considered REL S-series when shopping dual subs for my main room. Then I moved on - all things considered I think they’re overpriced. I looked at Rythmik, Hsu, PSA and finally ended up taking a chance on dual Syzygy SLF870’s, with some bank to spare ($$$). I haven’t looked back.
ps: consider moving your post to the Speakers forum ... it's a bit off-subject here in Music.
