I bought a pair made in china 2 years ago and contrary to what some may say, it works hard and is indestructible.
Pushed up to broadband and with at least 6 dB in the bass, it does not decrease even after 48, 72 or 96 hours.
I have even one who has fallen from 1.50 meters and there is not a problem of great stuff.
My only complaint: a major a bit short, but after EQ is all just falls into place and go.
Much better stuff in my opinion that many of powered speakers that are sold on the market.
