I have a friend who owns these speakers with an amplifier of the same brand (the low-end series)
The first thing that surprised me is his lack of huge potato fishing!
Though I push it (test the evening before) but nothing, even the pregnant Grandpa sends more decibels!
Then the sound, naze naze home. No sound detail. The sound was cold, lacked a lot of treble. The medium ... if you can say it was the medium of this forum. And finally the low stifled.
At this price, is not surprising to have a pregnant pourrite.
I advised my friend to change the speakers and put the kit GC7-112k B-String. But he said it was too expensive for him (€ 150 a pair ...)
A strongly discouraged even for beginners!
