since nobody replied to my last thread im gonna ask again. is a set of 30hz FMODs capable of protecting my sub from over excursion? my jbl bp1200.1 only has a LPF, so i need something for the lows. my box is tuned 32.4hz, and it will hold my new Q. are FMODs the way to go?
You will need a subsonic filter at around 25hz. this is essentually a high pass filter set @ 25hz. This will allow anything above the 25hz mark to pass to your subs. Set you LP dependant on what music you like at around 80hz. I listen to a lot of sloppy bass and jump from presets on my amp from either 65hz-75hz on the LP. A subsonic filter just keeps your sub in check and protect against any types of recording errors (pops) and is generally used in ported enclosures where overexcursion can be a problem. Polo..
it goes from 4v to 250mv. if i turn it all the way down to 4 nothing comes out, so i just cranked it to a good sounding level and left it. i will adjust with a dmm later.
if that were the case brad, why would it get louder when i turned it toward 250mv? lol, the amp is 4v - 250mv, the HU is what puts out 5v. im gonna use the subwoofer tools suggestions on amp tuning once i get my Q. pics will be posted as well. merry christmas and shitty holidays. peace
