For $35K, I'm sure you could cut a deal with your local Magnepan/JL dealer for a pair of Maggie 20.7s and a pair of Gotham G213s. I'm not so sure that the BGs the OP is shilling would be better.
Or pair the 20.7s with a pair of JL Fathom F212s for $10K LESS than the BG Radia FS 880s. I think those JLs would still be able to keep up.
