Is 200Hz LPF for a subwoofer too low? Would 300Hz make a difference?

[s*****[email protected]]

Hi guys, I have a subwoofer amp (1000watts @ 2 ohms) that has a
variable LPF built in. The LPF only goes up to 200Hz.

With certain songs, parts of the beat are pretty quiet, but low parts
of the beat (below 200Hz I assume) rattle my teeth loose. It sounds
horrible.

I'm considering selling this amp at a considerable loss to get a
similar amp that has a variable LPF that goes up to 320Hz (1300watts @
2 ohms, if it even matters). Do you guys think that this will fix the
problem? Is it just certain low frequencies that cause extra rumble?

I'm not sure what 200-300Hz sounds like... is it more or less
impossible to get a thump in that freq range, in which case I should
blame my music for being defective and having beats in freq ranges
that are unable to cause thump?

Another thing I plan on doing is replacing my factory 8" door woofers
with something more serious and have a 200-350Hz band pass filter on
them, so they can complement my 15-200Hz thumper in the back. My
worry is that they will not create the follicle-massaging bass to
match the rear amp/sub.

Thanks in advance to any help you guys may have to offer.

sounds like your sub can't handle low frequency's very well, and most
subs you don't really want to run that high, lp around 80 is more
common.

edit: lookin over your post again, is your box ported, do you have a
subsonic filter?

I have an Alpine Type-X (SWX-1243D) 1000watt 12" sub set to 2ohms.
I'm powering it with an Alpine PWX-1.1000 1000watt@2ohms amp.
Subsonic filter is set at 15Hz. Box is sealed, not ported. I was
just noticing that certain bass notes sound alot louder than other
bass notes... I figured it was a fault of the amp.. and maybe I needed
an LPF set higher than 200Hz... to 300Hz? Maybe it's just my music?

Any ideas?

Thanks.

Unless you're one of those ghetto people who know nothing about sound
quality and only use a sub that rattles their whole car to pieces.
