Occasional use since April 2014 This is my first pair of speakers in this category, but I could hear the difference between brands and models in the showroom: there's no picture!
Without being an expert, it is a very good product with good deep bass, treble not garish, and balanced medium. Excellent workmanship, sturdy and simple.
Used in mobile disco, they adapt to all styles of music, with a preference for current trends such as electro, house etc. ... It is very dynamic and when you push it hits hard without saturating without vibrate without busting eardrums. Everyone tells me "wow you got a great sound" and I say "I know!" ...
A big plus, boost the bass is exceptional for certain uses.
Regarding the price, although it is not cheap and there are less expensive but also less well. I think the price is suitable for manufacturing quality and rendering.
I repeat that choice 1000 times if necessary!
