Personally, there are many brands I'd look at before REL, but I would definitely look at a sub. My view is about a 180 from most on x-over frequency. I'd say cross pretty high for best results.
My reasoning is that careful placement of a sub will produce much smoother bass response than any speaker out in space possibly can - due to room modes/cancellation effects. Better yet, use DRC style bass EQ and the improvement is most often not only audible, but pretty startling.
In a carefully treated room, you can fix most of the mess down to 150hz or so and bass busters will usually get you into decent shape down below 100hz. After that, I let my subwoofer and EQ do the rest.
IME, the first benefit of a sub is smoother response in the critical 50hz to 100hz region, the increased LF extension and power are just icing on the cake.
Just one more opinion on this subject.
