When using the gizmo without a sub are you just supposed to boost the bass level in order to defeat the 100hz crossover? :no clue:
edit: I ended up setting the bass boost to one position below max by ear, but still would be curious how it works.If there is no subwoofer in your setup, the bass have been designed to give a boost that matches the roll off down to about 48 Hz . At max setting, it will give about a 2-3 dB bump at 48 Hz, relative to 100 Hz. So, with or without a subwoofer, the Gizmo will provide real-world performance.
