lowpt Posted July 1, 2011 Report Share Posted July 1, 2011 What frequency it is set will depend on what frequencies you want the sub to play. You want some overlap in the freq. the sub plays and the freq. the midbass speakers play. Quote Link to comment Share on other sites More sharing options...

MrSkippyJ Posted July 1, 2011 Report Share Posted July 1, 2011 (edited) if you use a DMM, the voltage will drop above your LPF setting. If you play a 68hz tone and get your max voltage reading(ie. 34volts) then at 69hz it reads less (like 31volts), you know that is where your LPF is set at. EDIT: sorry I didn't really read what he wrote. What he is saying is to set your amp to the desired voltage output, play a test tone where you want your LPF to be set at. Turn your filter adjustment down until the voltage starts to go down and then you know where your LPF is set.
