I "buy" these speakers yesterday with someone (in fact, we go back to the store 1 hour later).
These speakers produce sound awful, the horrors are pizeo is screaming at shou, brouillion, dirty, ugly, in short. They were part of a Master audio amplifier design DL400 was a horror (although this amp is good qualitée) Anyway ..
It's just good for teens who want to make small parties with friends.
