-How long do you use them: but never tested for in-store, if I was a night with this stuff, I'll make the room turned illico, I have too much respect for people who agree to inflict such horror.
- The most and the least: whereas most, good firewood to light the barbecue or careful the glue is toxic, less, well, uh the list is too long.
- Trial price / quality: a great scam, piezo tweeter 2 = 5 euros, a so-called piezo medium (a medium that piezo n'exite not and it will never happen) = 4 euros, a 38cm hp type pressed steel bowl a thickness of 2/10eme mm (take the quiz take the hp and give it a flick with your finger, it sounds a max hp must have a good sound as close to the clong ding) = 25 euros, a crate AGLO low-end 16mm = 15 euros, and finally a terminal audio plastoc = 2 euros which gives us a total of 51 euros if you make this crap yourself.
-Is what I would do this choice? : Well I am not so c * n to balance the money out the window, I do not even recommend it to a beginner in any event there is at least one person who knows more or less the sound, if you do not want not do a single evening take another brand (word of mouth is key to a dj, the more we talk about him much will be required for evenings, mixing is not everything must be pleasant sound the ears of people to dance if it is dégeulasse they go as far as possible the speaker to rest their little eardrums.
You can find it for a few euros more for behringer or Wharfedale.
It's just a board for you to provide personal time and it's been 12 years since I assure parties without gear boost.
