subwoofer crossover setting

[Crown_amps]

hello everybody ! i was wondering about what i should set my cross over at to cut out all the vocals from my subs, right now im getting my car set up ready so its running off a old school 4 ohm stable technics amp. SU8600 anyhow i have a pair of f mod cross overs set at 100 hz low pass ,,,,thing is i still get mad vocals on some songs and it sounds really really murky so should i get a pair of f mod 60 hz filters or get a cerwin vega cross over

i was thinking about getting this bad boy here

http://cgi.ebay.com/Cervin-Vega-Subwoofer-crossover-NOS-HT-210C-Audio-Bass_W0QQitemZ5871668674QQcategoryZ14993QQrdZ1QQcmdZViewItem

however thats rated for 8 ohms and im running 4 ohms x 2 off my amp should i find a crossover rated for 4 ohms? or will this do fine for home audio usage.

i have a 100 hz cross over currently and its just not doing the trick but then agian its just a harrison f mod low pass filter [ i hear they are mega lame] but it was a quick fix and now im looking for something a lil more beefy in my bass range and far less in the mid range which just makes it sound .....off.

current set up is

technics su 8600 > old school amp that can do 4 ohms safe its rated at 80 watts rms per channel [well i think like 76 to be extact] so it does do a wee bit of power i just went and boasted my cone area and got 3 subs to make up for the lack of all out power.

Woofers > two alpine type e's single 4 ohm coil 12''

Jl audio W0 single 8 ohm coil. 12''

the boxes are 1 sealed box at 1.3 cubic feet [ for the jl ]

one slot ported box at 2,0 cf tuned to 35 i belive and soon to build another ported box i have the plans and my wood is all cut i just have to get my arse down to my buddies shop.

this is all going in a smaller - medium sized room btw

once it's all done i hope it sounds better than now cuz the mid bass thing just kills me

are you running 2 type e's and the jl at the same time? //content.invisioncic.com/y282845/emoticons/nono.gif.eca61d170185779e0921b0faa9704973.gif

not at the moment i have the jl running at 8 ohms and one running at 4 ..

its a 4 channel amp 2 @ 4 -8 ohms and 2 @ 8-16 ohms .

still i dont think running 2 different brands of subs at the same time is good.

why would it matter if its getting the proper impedence?

 

[Crown_amps]

i would think most folks would say something about the 2 kinds of boxes...and about that i unplug the wires to my sealed box for music and use it to add on to the richness in films thats it i dont use it with my music at all.

Different drivers, different response curves, diffferent performance.

thats true indeed but for daily use its just the alpine soon to be dual alpines when that box gets done.

so will it be a performance prob or just have the sound all fu#@ed up?

 

[Crown_amps]

ok back on topic which would you use on this amp if only using the pair of alpines ? at the 4 ohm outs so i was thinking of getting new harrison labs "f mod" low pass 50 hz or 60 hz cross over [ 29.99$ for the pair]http://www.streetprices.com/Electronics/Consumer/Automotive/Car_Stereo/Crossover/SP2213764.html

or i can go the route of cerwin vega subwoofer crossovers like the one i showed above off ebay

me hate when ppl "let" the drums of a song play through the subwoofer..unless the producer of the song meant for the drums to be accompanied by subsonic frequencies.. my xover is set to 52 hz biatches!
