Should I worry?

I'm still catching myself staring at Devialets  woofers, hipnotized by the movement, how they work in tandem to produce bottomless bass.(huge grin).
Anyway, whatever Deviatet's inventors did is truly ingenious.

Please make sure you put them on stands and place them properly in room. Treat them like you would any decent speakers. Done right, the Golds will match many high end systems.
