[QUOTE="squeak9798, post: 512724, member: 555320"] Subsonic filters and crossovers don't just kill the frequencies below or above the SSF/crossover point (a subsonic filter is nothing more than a highpass crossover with really low crossover points). What SSF and crossovers do is [I]attenuate[/I] the frequencies above/below the crossover point at a given slope (the slope should be stated somewhere in the owner's manual). For example, if your SSF has a slope of 24db/octave, then it attenuates the frequencies below the selected frequency at 24 decibels per octave. If it has a 12db/octave slope, then it attenuates the frequencies below the selected frequency at 12 decibels per octave. EDIT: **** boys, we all three posted at the same time.....good work [IMG]//content.invisioncic.com/y282845/emoticons/handclap.gif.0c301076f534e244f0460706894f19e0.gif[/IMG] [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] [/QUOTE]
