no and no but i am also very interested in the 4000's or a similar set. you might also want to look into the polk rm7300, rm7302 center, and psw505 as a alternative set. simlar specs, lower frequency response, different materials, different enclosure. also B&W FPM series. those are a little more, the largest of which (fpm6) costs around $900 A PIECE!
Klipsch also offers a similar series in their reference line (rvx) AND synergy line (slx) (reference being better, i believe). I ruled them out b/c of slighly lower power ratings.
going down along the chain, IMO, there is also orb audio and bose to look into.
there, thats all i know. please post if you find any good reviews or comparisons of speakers such as these.
