I will not dwell on the description and the resulting sound of these speakers, the photo alone says a lot ... (See Boost, Mc Charlow, etc ...)
on the other hand I find it absolutely unacceptable that companies supposedly professional entertainment uses such material, making still pay the customer a benefit that is not at all proportional to the quality of equipment.
Whether one buys it for mumuse in his garage with some friends I can understand, that buys amateur DJ to start happening again limit, but not professional anyway! There products more affordable and widely style Yorkville YX Series or the new range which I think Alto is the minimum that we can require such providers ...
