I recently purchased my first real rig. Swr 750x (750 watts 4 ohms) and a goliath senior cab (6x10 1000 rms). After rehearsing a few times I am concerned with the lack of "headroom" I have. From 0-5 I have low volume, from 5 to 7 on the master I have decent volume and from 7 to 10 I have great volume. Is it mormal to run this kind of set up at 3/4 power? To tell the truth I expected not to go past 5 ( this stuff wasnt cheap). I appreciate any help.
