what does this mean

[bigarsenal]

okay on my head unit it has sw-phase you can set normal or reverse what does it mean reverse im lost :-[

[andym85]

i believe when u set the subwoofer phase to reverse it acts as though you have invertedly mounted your sub..mine actually sounds a bit louder set to reverse, hardly noticeable though

[AI James]

i thought phase had to do with pos neg inputs rather then inverted or not.

i thought phase had to do with pos neg inputs rather then inverted or not.

from what ive read, it does. when you sync both amps on one sub, you can select 180 degrees on the amp with the negative. on the head unit, if you feel a delay in bass, you select that and somehow itll compensate i believe.

cause i got them set reverse and they sound good

[andym85]

dont you wire subs backwards when u invert them? if so...aren't me and accordman saying basically the same thing...or am i just wrong, as usual...lol

[AI James]

ive never ran inverted so i cant call you wrong, i just see speakers out of phase that are mounted normally, soi always thought phase had to do with the wiring

[andym85]

yea...thought phase related to wiring too...u are saying wired backwards, im saying mounted inverted (which implies wiring backwards imo)...so its all the same i guess...idk :-[

You guys are pretty much there!

Phase IS talking about how the subs (or any speaker for that matter) is/are wired.

Why it's important-

1: when you want your mids to play together (and thus louder) they should both be pushing in and out at the same time on bass notes even if it's midbass/midrange Hz.

Also-for the correct "stage" or "imaging" like if you have a track that fades left to right or front to rear etc. If your mids are out of phase (one wired +pos to +pos from amp and -neg to -neg from amp, and the other flipped +pos to neg from amp and -neg to +pos from amp) they will be working AGAINST each other, not only sound funny but be less loud.

2: Same goes for subs-especially imortant since we all need face smashing bass or as much as we can get-phase is important.

An out of phase sub will work AGAINST a sub wired in phase they will be "180 degrees" out of phase (exact opposites) and likely cancellation will occur=bad.

THIS happens a lot in setups where more than one sub is used and only one or SOME of the subs are inverted because one sub is pushing forward (cone out of basket and away from box), while another INVERTED is pushing forward (cone out of basket INTO box) and instead of compressing the air in the box it's actually just equallizing it -one woofer cone pushed in (-1) and one pushed out (+1)..-1+1=0..zero bass is no fun (this is assuming it's common airspace not divided for each woofer).

I've never had any issues since i either run all inverted or all standard mounting, and I'd venture to say as long as you wire it reversed for an inverted sub along w/ your regularly wired standard mounted subs OR VICE VERSA you shouldn't need to use the phase button...So really i dont know why that button is there unless its for lazy bastards who dont wanna re-wire anything after they screw up the pos/neg on a set of spealers/subs...and ALL the signal would be effected by one deck button so i dont understand for sure what good that would do either...unless it were subs in relation to mids being out of phase and you needed to sync the 2 systems?

Thats as much of an explaination as I can give right now since I should eb awirting a damn midterm paper... if I'm wrong on any of that I'm sure some O.G. member will flame me down into my rightfull noob place and correct it.

~My 2 cents hope that helped.

im so lost so me putting my phase on reverse is saying my subs are inverted. they do sound different on reverse but my subs are mounted normally
