I haven't used Rel subwoofers with my La Scalas, but I have used a single Rythmik F18. It blended in pretty seamlessly with crossovers at 80Hz. When I wasn't using an active crossover, I set the sub's built in crossover to 50Hz and it sounded just fine. Highly recommend Rythmik. As far as placement, the ideal location would probably actually be sitting on top of the speakers. 36 pounds won't hurt them. Dual subwoofers are fairly highly regarded and I can definitely hear the "bumpy" bass with the single F18, but it wasn't a huge problem to my ears. The one thing worth noting is that I had to crank the gain up on the F18 just about to the maximum to properly match with the LS using a 30 watt solid state amplifier, so the little Rels may have trouble keeping up with the LS if you like to crank the music up to party levels regularly.
