I use it for 8 months and it is pure sound (bass RFLEX)
I use it in visional 100,300 people in live outdoors Maxi (fair) and it spreads across the room or in the city.
the only weak point it tilt so quickly enough to be monitored during the night.
if not buy, it is a good can CHRE but the quality that is priceless.
FYI I hatchet another.
