no bass boost?

[Hydrastas 10+ year member]

I've seen in numerous posts that bass boost should be off, however i can't seem to find a thread that says why that is... Whats up with that? I know that if i turn down the low on my hu that i can get more volume out of the speakers before distortion, but why no bass boost for the subs?

bass boost will boost a certain frequency (usually 45hz) and it'll clip the shit out of the amp, and blow your sub hella quick.

it's also known as the "sub killer"

why is it even put on amps then? I've been using it for a month now since i bought my amp and i've heard no clipping, and the subs seem to be just fine. Im only running 360wrms though, maybe it has something to do with the 1k+amps?

Im also using sealed boxes, should i listen closer to check if it's clipping or what?

yeah you can use it conservatively, but at higher volumes it'll clip alot. if you do decide to use bass boost, then set it to where you want, THEN set the gains so you won't be clipping the amp. at lower power, it'll last longer cuz it's not pushing the sub as hard thermally like it is at higher volumes.

so is bass boost like running more amps through the sub? Could you get the strongest possible signal from an amp without using the bass boost?

Like if an amp is rated at 250wrms x 1 @4ohms, is that with the bass boost or without it?

no. the signal comes from the HEADUNIT. teh bass boost BOOSTS a certain frequency (usually 45hz) so the output of the sub will increase but at the expense of possibly damaging a woofer if you don't kno what you're doing.

it doesn't provide more "power". it intensifies a certain frequency for higher output response at that frequency.

which makes the woofer act like it is getting more power than it should... sometimes causing it to go beyond it's thermal abilities... aka, it blows...

bass boost = newbs

if it isn't loud enough, get more power! //content.invisioncic.com/y282845/emoticons/thumbsupwink.gif.129404938effda6ad9cca39e7f4b58a3.gif

how is that possible without more power, thats confusing. Does it just take what power it has and focuses it on that frequency or something?

 

[dkguitarist 5,000+ posts]

it amplifies that signal. yes. thus it causes the amp to clip because it's overworking itself to keep up with the demand. i've blown 2 or 3 subs like that (entry level rf subs).

but what if im using 2 subs that have 350wrms each, onto an amp that is only giving them 180wrms a piece? If a woofer acts like it's getting more power than it should, wait a minute, how can something act like its getting more power?
