hey i have my eclipse SW8102.4 10 inch sub in a crappy best buy q logic single tiny box.... my bass sounds like crap..... only thing that sounds good is rap but when it comes to rock it just sounds like an earthquake.... i cant hear the kick all i hear is delayed deep bass.... could anyone tell me what kind of box i should use or where i can get a cheap one built. i could build one if i knew the measurements to use.....this is the subs specs....

What are your amp settings at?

You have the measurements...

 

what is the internal volume of the current box?

 

tell u the truth i dont know wat their set at. i have tried every possible setting and it still sucks. my amp is an audiobahn like a800t or some thing.... its crap ino.

ino i have the volume and stuff that i need for i dont know how to convert that into like length width and height form....

 

bcae1.com click on #110 that will help.

 

dont exactly know wat u mean by internal volume but it says .65cuft.....which now that i think about it is no where near as big as it should be.... but will that kill the sound?

 

Yes it would. If it's sealed your sub is effectively suffocating.

 

so should i build a ported box or just the right size sealed box.....




by the way i just have to mention that the red sox are winning 11-0 right now.... hadda throw that in for those that care lol

 

I'd build a nice big sealed box...

 

i think i shall.... im also using an 8g wiring kit.... since the sub is 500 rms and "supposedly" getting close to that with the amp would upgrade the wire have any benefits.... as you can tell i took the cheap way out of everything and now im sick of crappy bass

 

I would upgrade to 4 gauge but more importantly make a box thats air tight and the proper size.

 

small sealed box, and yet boomy bass response? check the xover frequency on your amp. it might be set a little too high.

 

yea.... i need to find someone in the rhode isalnd area to meet with me and listen and help me..... any volenteers?

 

hmm, it's easy to check. do you know the exact amp model you have? we can coach you to check from here if you know the model.

 

its the audiobahn (crap ino) a8002t.... i have a jvc 5100 (the one that plays dvds) and im using the bose speakers for now.... my problem is that i want the kick to be heard more so than it is.... all that comes out of my subs is like a delay kick and insane bass.... as i said for most rap songs it sounds good but i dont listen to just rap

 

alrighty...see "x-over" on the left part of the amp? set that to LPF. then on the dial right to that, is the **** to adjust the x-over frequency. where do you have it set to? turn that dial to about halfway...which is roughly 80hz.

 

I would reset the gains and crossover frequency. Its probably too high. Also if you have a bass boost setting, set it to zero.Get some polyfill if you haven't already and stuff that box.

 

polyfill won't help with punchy response...might actually make the situation worse by actually augmenting boomy bass response. smalled sealed enclosure should provide a nice punchy output. only thing i can think of is the xover is set way too high.

 

ok ill try this.... polyfill? lol care to elaberate

 

basically pillow stuffing. when used in a sealed box, it tricks the sub into thinking it's in a larger box, helping with the lower bass output.

 

it helps the sub sleep at night so it can be rested the next day to perform well.

 

Bwahah. Having fun?

 

any house hold items i can use in there instead.....

 

its like $2 a bag at walmart or rip apart a pillow you are using now.

 

lol.... alright.... ill give it a try

 

do it...it does work but don't expect miracles.

 

i have the same box from worstbuy, it's .65 but mine is dual... add the polyfill cause it does help a slight bit.. BTW what x-over freq. do you guys recommend as a "base" setting or does it just depend on the sound your looking for?

 

depends on your setup and how well it blends with each component. i have mine set at 80. no point IMO for the sub to play any higher where a decent component set should be able to reproduce.

 

yeah i agree, have mine set around 90-100hz

 

Just out of curiosity...why so high?

 

yeah, 100 hz a bit high imo...

 

80hz is a good setting.

 

I have mine set at 100. I find that I like the sound better. It may be me, but I have never had anyone sit in my car and say they could even tell.

 

Rich, could you tell I was set that high?

 

No and I honestly don't believe you. JK, however I believe your subs can handle it with ease. Next time you roll by I wanna really listen to see if I can tell.

 

Will do. Maybe Monday after class.

 

I dunno seemed like a good place to start, maybe i'll go down to 80hz with the new subs.... I don't like that high, vibrating my trunk bass anyway.

 

from my experiences...low freq does a hell of a lot more flexing on car panels thann higher bass frequencies.
