Last december a made a small modification in my sound package.
1-The main sound syst. still is a Peavey powered mixer,two JBL speakers and a small Yamaha MS60S for feed back (with a loop system developed by UD)
2-Then I introduced more one amp(100W) with a small crossover connected in a Bazooka(Sub woofer 12'')only for very low frequency.
Now I can set my mixer with a treble ajustment and still have a nice loud sound.
