I agree with RAS. I use a JL Audio F113 with B&W S800's. Easy as can be to set up. I do not know what you are using for your mains but I run mine full range so no active crossover is needed.
The other question is why do you need a remote for your sub? It seems like you will use it once to set it up, then take the batteries out, put it in a palstic bag and store it. I never adjust my sub. Set it and forget it.
