Best light weight full range speaker recommendation.

I love to experiment with sound and so far has been mostly constrained to book shelves, (Persona B, Formation Duo) or low sitting speakers (Heresy IV) all of which require separate subs (maybe not the formation). Now for full range speakers, it seems like the new Beolab 28 is really the most lightweight one out there. Kinda wonder what other options are there, or rather do any of you mount speakers on wheels?
