LSC Posted August 1, 2019 Report Share Posted August 1, 2019 Sooo here we go.. As the title suggests I've somehow managed to fry my first pro audio speaker... Not really proud of it but I thought I'll make it a new topic so me and others can learn from my mistake and maybe some of the more experienced members here can give us a lil rundown on how to set the limiters right. So let me describe what happened: I was having a lil snooze around 4 at night when someone came up to me and said that the dj requests some help... I went and had a look at the amp rack to find my NX6000 turning on and off because of protection mode.. I couldn't believe it but after sticking my nose into the vents of my skram I had to face the reality that my beloved 21ds115 which seemed so indestructible had burned it's coil x( I fully deemed this impossible as the NX6000 puts out 1.8-2kW sines and it was a techno night, so no prolonged sinewaves like you'd have with dubstep or bass music in general... Butttt; now I know better and I suppose it was just getting hotter and hotter as the night passed by and thermal build-up was getting too much at some point?! Or could it be that steep filters are just better than the 12db BW I was using as high pass filter? Could it be that the DJ made the signal clip and the DSP somehow produced a harmful signal? Now to the prevention of this happening again.. Does it make sense to add a temperature sensor to the magnet of the driver which can be read by a handheld thermometer or perhaps even an arduino to monitor the temperature and adjust accordingly? Can someone please explain how to set limiters in the right way so nothing can get hurt but no bass resources gets wasted? ...I already thought of running sines, measuring them at full amp throttle and set the limiters according to the RMS rating of the driver but that seems (seemed haha) like overkill.. Please share your thoughts and tips fellow bass lovers so I can assess what went wrong and how to avoid it next time as this was a quite traumatizing thing to happen on the second occasion I had my skram out and about..
