Would you say you are missing the "punch" of a kickdrum and the like? How are your midbass's installed? I would also cross your subs over a bit higher, around 80hz. Tuning at 32 hz will lead to a big hump in your response regardless, but a good install of your midbass's (/midranges) should pick up the higher bass notes fine

lol i have no problem wid midbass just that when i cross too high it sounds really punchy and not to my taste i like to sounding smooth low and blend with the music even with a seal box sounds identical but ported box gets lower in my car. Example since i cant bypass my amp lpf i turn it to the fullest which is 110 hz and use the deck lpf which is 80 hz @ 18 db and set gains and it sounds punchy doesnt really blends with the music and the low end isnt that noticable. On the other hand if i use a 24 db crossover and set lpf @ 45 low notes sounds amazing and sounds much cleaner but all the punch is gone i just wish i can get a smooth bass responce in car a balance between the too.

Sounds like you dont like your box, I'd try either tuning lower, or go sealed (what I would do)

well i tried it sealed but it doesnt make a big difference i think my best bet probly is to keep it cross low till i can figure out the problem

maybe you need to turn the gain down some when ur setting the lpf higher?? i use to have my x-over at 50.. but i was kinda missing some higher sub-notes and was getting anal about it.. so i now have it set at 82.. i EQd my components so that it has a little peak around 90 hz.. so it blends a little better for me with my higher xover point.

how big is your ported box and whats it tuned to?

 

[bassaholic 10+ year member]

it is the recomended ported box jl specs for the 12 w6 v2 tuned @ 32 hz

 

[bassaholic 10+ year member]

I just came from outside and i used the lpf on the deck which is 80 hz @ 18 db and it sounds down right crappy the notes sound like if they are clashing with one another (jumbled) and im hearing a hint of voice when i go close to the sub

 

[nauc 10+ year member]

use your deck crossover OR your amp crossover

not both

and set your gains right

test tones here, under downloads ----> http://www.realmofexcursion.com/main.html

somethins not right, you shouldnt hear vocals

 

[bassaholic 10+ year member]

i cant bypass the amp crossover and to me the amp cross over sucks cause even if i cross it fairly low i still notice a hint of vocals comming from the sub and the bass sounds crappy //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

are you using a dedicated subwoofer output or just a front or rear set of rca's off of your deck? i agrre with using only one or the other instead of both.

 

[bassaholic 10+ year member]

i use the sub out of the H/U well wat imma do is use this 24 db crossover i have and adjust it till i get a good mix of loud and low end.

 

[bassaholic 10+ year member]

What you got your Subs lpf at and with what slope? im not comparing im just curious
