If you can localize your bass, it's simply because you have your sub crossed over to high. A subwoofer is supposed to play sub-bass. Sub-bass is anything 60 hz and below. When you start having your sub play high frequency stuff, it makes the music sloppy and allows you to localize the origin of the bass.

Did you try the suggestions I made earlier? Disable all the headunit crossovers and use your amp crossovers at the frequencies I suggested. If it doesn't work, then oh well, but I'd almost put money down that it will fix your problems.

I listen to primarily rock / hard rock / acoustic stuff myself. You don't want your sub playing 100 hz sections of music. It sounds like ass.

Maybe its out of phase?

Make sure you dont have the + & -'s mixed up...

i dont have any rear speakers right now..just fronts...

im a little worried about setting my bass at 60hz because the majority of what i listen to is rock...will 60hz and under pick up bass drum and bass guitar etc? My CDT's arent anything special when it comes to midbass..they are clean hitting but not necessarily made to keep up with a xxx.

one thing i cant really figure out: the sub sounds so distance...it sounds like i can tell where the bass is coming from, and it sounds sort of far away. With my PG's it wasnt really like this, it was more "surronding" so to speak. Why is that?

i had the sub at like 75 and it didnt seem to pick up enough frequencies...like on songs with 3bass notes it'd pick up only the last 2


this sounds very familiar, and i have had this problem with 2 out of my 3 sub set ups, my problem was that 2 of my boxes would pick up the lower notes and the upper notes would be silient like if they were not there, they werent really high like 80hz because my speakers would hardly play em so ive been left with a big gap in the bass, this happend with boxes prefabed of custum built, the ONLY time my sub played frequencies very nicely all around was with my my alpine type R that came preloaded in a box built my alpine, but youre case can be difirent, IM me ill send you some songs and ill see if you got the same problem i do.

If you say so.... :)

I'd probably disagree with you if I listened to it, but its your system, so you should have it tuned to your liking. It's probably a good bit louder than if you had it crossed at 60 though. Keep this in mind, most people interpret louder music as better sounding music. It's not true, but a lot of people think that way at first.

I can explain exactly why you should crossover your subs low, and how it works with your front stage for a sound quality application, yadda yadda yadda, but I'm at work right now. So anyway, perhaps I can type up a little article later on explaining it.

I have my sub crossed at 125 or somthin like that maybe 100, it sounds great...

by Dustin from Huntsville » Fri Dec 17, 2004 7:14 am

Just use the crossovers on your amps and disable the head unit crossovers. Try to run your front componets crossed over as low as they can without distortion. Hopefully they can make it to atleast 60 hz. Then run your sub below that. You want the front components playing as much midbass as possible to keep the overall base sound to the front of the vehicle. Plus I find that anytime a subwoofer is playing 80 hz or higher, that the bass sounds extremely sloppy. I try to set LP filters on my subs around 40 to 60 hz.

This advice is given based on trying to acheive the best sound quality with a given system. If you re more interested in SPL, then setting the LP filter on the sub higher would be more likely to acheive the results you'd want, but at a greatly decreased level of sound quality.

What comps are you using in the front? IMO rear fill is a waste of time & money because the subs will drown that out (in my Xcab truck anyway).
I have my comps at 80Hz as well as my subs (but I also have a 24dB slope on them)

by Ryan from Ohio » Fri Dec 17, 2004 6:21 am

I would use the Head unit to cross over the sub amp at 80 Hz

The highs you would be better to use the crossover on the JL amp.

IMO for the fronts around 150 Hz the rear fill aroun 90 Hz 12 dB roll off.

by progrocker » Fri Dec 17, 2004 3:08 am

I would turn the high pass on your HU off and use the 95Hz you have set from your amp. Leave the sub at 80Hz from the HU and try to set the same on the amp.
