I use them for 1 year and I really very satisfait.ces following speakers are equipped with technology Direct / Reflecting (mixture of reflected and direct sound) so they are equipped with a tweeter in the back and it gives a realism sound.
course for those interested in trance or techno drop bose but otherwise you can go there, I used to men hifi speaker or possibly for occasional evenings and they are doing no problem!
they are pregnant that I recommend for those interested in sound quality, of course they are expensive but I find the price well justified with a good amp because they are from hell!
