Subsonic Filter

Is there a slope on it? -12 or -24db? If so set it at -24dbs. and if your box is tuned to 34hz set it at 30hz the subsonic has a variable bandwidth in it. so setting it at 34hz is no good because it may start to drop Power at 38hz so set at 30hz. always put it 4hz below you're tune for vented. below your tune you're subs will start to xmax very very easily And as you know this can damage them. allot of people tune there subsonic to the fs of there sub. witch in a sealed box is fine. but vented this can be dangerous! i Hope this Helps.

note. if yyou can adjust the center or q of your bass boost make sure that your q isn't to low andbcentered at your box tune at 34hz. say your q is at 1.2 and your boosting +6dbs at 34hz. with that set up you are inturn boosting 30hz at 1+dbs of boost. hope this helped pm me if you want some more help. i run the jl /v2 amps and it took me a long time to truly understand what all the settings do And how they can effect oneanother

Why do you think no one helps you? You claim to know things that are obviously above your skill level and then turn around and ask questions like this. After this response dont be surprised if the few who gave quality advisce as you call it dont bother either.

I play full tilt way below tuning, like 20hz when i am tuned around 33hz, if i hear coil hitting the back plate i turn up the ssf till it stops.
