I have a pair of your QSC KW153 speakers, paired with the Bins and i am having some problems with them. When i am using the speakers KW153 with the bins i have them set to EXT-SUB. This sounds great but on certain tracks I'm playing at volume i am hearing a distorted sound which seems to come from the mid-range. It also seems to happen when i use the microphone also
This is not a problem i have heard before but does concern me. The speakers are never used in a clipping state so not driven hard. They are used for Dj work so northing heavy. I first heard this sound when i played a song by 'the contours - do you love me' from the film dirty dancing. In the song when it does like a chorus part of a drum being hit about 7-10 times per second, it seems like the mid range driver breaks up.
The speakers i brought around 10 months ago now. I did have an issue with them previously where one of the top speakers made a very loud sound, like a needle being pulled across vinyl, and then all the power went as the speker manage to trip a 32amp supply. The speaker was repaired but i have concerns of something similar happening again which gives me doubts about the products.
I have thought about buying a pair of the kw152 cabs to cut out the mid-range driver, would this help or should it not happen full stop?
I hope you can shed some light on this issue I'm having with the distorted sound. Its very similar.
