Construction is very simple, if you have purchased the appropriate accessories before.
I use the system with a Pioneer AV receiver 923k 7.2, a Oelbach 3m Subwoofer Cable, 30m 2.5mm2 speaker cables, vibration dampers and banana plug've bought previously.
Thus the connection was easy.
The AV receiver has the boxing itself set for calibration, so they sound great.
I get a nice Bluray really mad, because one can perceive the sound as fine and differentiated.
Visually, the boxes are great. I have a shelf Wall (Hemnes) in almost like color, so you perceives them much less, even though they're quite large. The tower speaker are, after all, about three feet tall.
The manufacturer offers if I remember this correctly on 12-year guarantee, which is a great gimmick.
In addition, you can buy there on wall mounts and stands that fit well optically.
Overall, a well-rounded!
