    Icon32 Subsonic filter needed when tuning low?

    I'm considering tuning low for SQ reasons. Not sure exactly what hz to shoot for, but I know some of the music I listen to has bass notes as low as 25 hz.

    So if I go 25, can't it play a few hz loewr and still be ok? I believe I've seen some bass tests with 20 hz, would that be ok? If I understand correct, a box tuned to say 40 that plays a 25 hz note would be the big no no, right?

    I was trying o figure out what size box to build with Winisd program, but it doesn't seem to be working too well. Are there any other resources for building the right box? I don't mind learning new things, definitions, calculations.....in fact that's exactly what I wanna do

    Thanks

    winISD shows you cone travel and it might be a good reference to see if you need a SSF filter at all, and if yes, what the value should be.

    just make usre you input power going to the subs.

    Your box will be fine up to a half-octave below it's tuning frequency.....so if you had it tuned to 25, you should experience no problems with frequencies as low as 19 or so. You can tune the box to 30hz and theoretically you should be fine with those 25hz bass tests without a SSF.

    Cool, I'll play around with the winISD some more.

    I doubt I'd hit anything below 19 hz, so that sounds good

    I doubt you'll find too many tracks below 19Hz, nevermind it being audible. Of course, if you like pipe organs and sick bass test-tone CD's, then a SSF would be a wise safety option.

    there is no set frequency, but on average, it'll hit between 40~50Hz, I'd imagine. Rap doesn't really have THAT low a frequency(except specific songs that dip to about 30~35Hz.

    Just don't play any bass test CD's that are supposed to go down to 18Hz.

    If you really want to go for SQ, make a sealed box. As someone said, don't underestimate the sealed box.
