REL subs with Acoustat 1+1s?

I've been searching on-line but my Google-fu is weak today apparently. I'm thinking of moving on from my RH Labs sub to a pair of REL subs. Two reasons:
  1. First, the RELs are self-powered. This should ostensibly leave more power for the ESL panels as my ARC VS-110 would not have to drive the RHL sub.
  2. The other is to have better distribution of lower frequencies in my room.
The problem is that I can't find a resource that tells me how crossover duties are handled for the full range speakers in the system. My current RH Labs sub acts as the crossover and does all of the lower frequency work while passing the mid and upper signals to the Acoustats. It appears the RELs have an adjustable crossover but that it only controls the sub itself. Does that mean that the ESLs would still get a full spectrum signal?
My other question is, how to I get signal to the RELs? Run another set of cables from the amp to each sub?
How do you folks with RELs and ESL panels do this?AdThanksVance.
Happy listening.

The 1+1 go down to around 30-40hz -3db, to get the best dynamic swing and kick out of them you should limit them to >120Hz.  Use cheap ready made passive high pass xover to do it with as I showed in my first post.
This will get them loud without straining them and making them limit trying to do low bass. With the sub/s below that <120hz.

Over the years I had the 1+1’s and the 2+2’s and (ML Monolith, with active bottom end), don’t take the sub/s up too far in FR as they can’t match the ESL’s speed anything above 100hz.

And passively roll off the ESL’s with 2nd order high pass, at around 120hz-150hz, like this sort of thing with air core would be better, but won't be practical.

(if you use active on the ESL’s say goodbye to the natural sound you’ve been used to.)

If your looking for "low tight bass" to match it with the esl’s speed, get a quality "motional feedback controlled sub/s" that’s 10"-12" with active xover set at around 70-90hz and use line level to drive them.

And spend time getting your phasing distances right and don’t have the subs volume up too loud, so you don’t hear them all the time.
