Heavy

It is a nice speaker, but very heavy if it has to be carried up 2 flights of stairs.

Awesome stuff.

They are going fast
Generally no distortion of sound at full blast
Beautiful and sturdy design
No disadvantage for me, but they are big so really for large surfaces

Have 2 because 1 is also so lonely. With 2 it is a perfect set on a large surface.
