Re: QSC KW181 stacking (placement) - NEED ADVICE!


The KW181 has a low pass filter that it uses internally and QSC states the frequency response to be 38 - 124 Hz.  The KW 181 does not have a crossover or high pass filter for routing mid/high audio to the tops.


I have 4 of the KW 181 subs and 2 of the KW 153 tops.  I stack two of the subs and put a 153 on top of each stack. 


The 153s are set to "External Sub" and the system nicely fills any indoor or outdoor venue where we may play.
