I would not consider mooving from Micro Be to Diablo as mooving up in Focal stand mountened speakers line. they are too diferent and need to be heard. Diablo has much more details, open midrange and are way much faster- I would not consider it as laidback in any means. if you are looking for polite,laidback sound Micro Be could be so so, but definatley not Diablo.
Diablo however will benefit from subwoofer(up to 45HZ) very much.
