I must add my voice to because all the 5 star reviews make these speakers appear as if they were real bookshelf speaker with Hifi sound for connoisseurs of the 3-star group. That's not so, - I am not a HiFi freak but I can distinguish clean sound of unclean and verbrummelten of bass heavy. The Control One are compact boxes that are well made and sound neutral enough that I'm going to keep it; they surpass the previous Brüllwürfel significantly in tone but they are not HiFi bookshelf speakers (as it sounds in the 5-star reviews). The sound is clean but straight down towards not really compensated for me (it sounds a bit like the old Windows Media Player - bass sound "ploppig" so corrupted (missing bass I would find better than distorted, but then the Boxem would probably 4 or 5 star wars;))). There are monitor speakers but do not sound that was already unclean.
Fastening material, incidentally, was included in my package.
Addendum: With a small, powered subwoofer in front of the speakers results in a very good sound.
