I use these speakers for almost 2 years for services up 250 people.
Good power handling (it seems to me more than 300W, the Samson SX 1800 rsistant of 2x400W / 8ohms, bumper clip!).
There is indeed a serious lack of prsence in spite of legalization that the spectrum appears quite small in homognes config.
The finish is relatively average strength level but good for the price ...
I am considering an enhancer / exciting for the sx1800 derrire low but, I admit that it scares me, so I will wait to be reassured on this point by returning expriences user.
I certainly would do much better choice because it is a vulgar piezo speaker in the same price range!
