super .. I've read reviews rather complimentary about these speakers .. but I had no idea they were really as powerful ... a real treat to travel to listen to my ipod in the whole room really for .. that price ..I wonder why I did not buy them earlier .... good one regret about the sound that tends to pull too much on the treble .. but it's really not super annoying. ... finally go quiet .. there is a very good buy amazon ..and as always are the best in quality delivery and serious ....
