I use them for 5 months now. I bought used in June 2004 to 250 pice and they seemed to have a lot dj served. they are 250 watts RMS into 8 ohms.
I use them for singing in my band, and for small concerts, both say that since I have, I use them extensively and trs I did not falter once seen, they are nickels, and as its name suggests they Pulse, while perfectly restoring the sound spectrum and providing a powerful dimension to the sound, in short it's not cold, it's not ugly, it's not drooling! rather it is warm, round, strong!
